My HP, purchased in June 2012, died on Saturday. I was working in recently installed Photoshop, walked away from my computer to answer the phone and when I came back the screen was blank. When I turned it on, I got a Windows Error Recovery message. The computer was locked and wouldn't let me move the arrow keys up or down and hitting f8 didn't do anything.
I'm not happy with HP. Any suggestions?

We’ve recently announced the changes to the BT Infinity service and thought it was a great chance to get our Infinity experts on to the community to tell you a bit more about that and answer any Infinity related questions you may have.
Our experts Charles and Martin will be chatting with you on Tuesday 15th May at 7pm.
The format is pretty simple – simply come back here on that date and the box you see below will turn into an area where you can submit your questions. Enter your email address in the reminder section so you don't miss any of the chat.
BT Infinity Expert Chat Transcript
(05/15/2012)
7:00
KerryG:
Hi Everyone, let’s get the chat started! Welcome to our live discussion with our BT Infinity experts.
7:01
KerryG:
Today we are joined by Charles and Martin from the Infinity team. Welcome everyone!
7:01
KerryG:
Today’s chat is tech focused on BT Infinity, so if you have any individual service queries, we can’t answer them during the chat, sorry. Those queries can be raised in the forum as normal. This chat is focused on the Infinity service itself, all comments will be moderated and the usual forum terms apply.
7:01
Charles:
Hi everyone!
7:02
KerryG:
We have our first question...
7:03
Comment From GedGed:
my wired infinity speed is 54 kps but I can only get 20 when wireless - any way I can improve the wireless speed - Thanks
7:04
KerryG:
We're typing up the answers, so bear with us as we get the answers through to you...
7:05
Charles:
Hi Ged
• Upgrade your computer to ‘N’ standard wireless hardware. If needed, buy a suitable N wireless adaptor from BT atwww.bt.com/nwireless
• Keep your computer streamlined eg. by running our ‘PC Healthcheck’ app (part of BT’s Desktop Help software atwww.bt.com/desktophelp)
• Reserve wireless for mobile devices, use Ethernet for main computer
• Consider powerline adaptors for longer ranges

hi all
7:06
KerryG:
Hi gooch - thanks for your question, but this is an Infinity tech chat so we need to keep it on topic if you post in the Phones board there's lots of helpful community members that will help you out with your query
7:07
Comment From Neil Potter
How soon after an exchange goes live with Infinity will BT allow other providers to sell Fibre To The Cabinet services from that exchange? My existing ISP is waiting to announce pricing details to me so I can make an informed choice. Thanks
7:08
KerryG:
Hi John Good to see you on the chat - who else is here?
7:09
Comment From Chris
Hello world.
7:10
Comment From Helen
hi all.
7:11
Comment From Paul
Are we able to get fastpath on BT infinity,or will this ever be available ?
7:12
Martin S.:
i Neil. When Openreach enables an exchange for fibre, all internet service providers are able to use that service equally - so other ISPs should be able to offer their fibre products at the same time as BT Retail's Infinity product
7:12
KerryG:
Thanks for all the great questions coming through guys... answers being typed as we speak!
7:13
Charles:
Hi Paul, We don't support Fastpath on BT infinity at the moment, I'm afraid.
7:13
Comment From Helen
I've recently upgraded to Infinity 2. The ethernet connection is fine, but the wifi is constantly dropping. I have an old Homehub 2 , which we had for total broadband, will it work, so I can test the wifi.
7:14
Comment From Simon
Hi all
7:15
Martin S.:
Neil - also its worth remembering that when an exchange is enabled for fibre, this does not automatically mean that all cabinets and lines connected to that exchange are also enabled, which might explain if your exchange has been enabled but your line is not appearing as eligible yet
7:16
Comment From Kevin
Whats the upgrade path from fttc to fttp does it mean a new contract or can we just expect it to migrate?
7:17
KerryG
Out of interest...are those on the chat existing Infinity customers or people thinking about it?
7:18
Charles
Hi Helen, your wireless should work ok on your Hub 2, though our more recent Hub 3 is better. If you're expereincing drop outs, it's usually a sign of radio interference. Have you any powerline adaptors you could use instead?
7:18
Comment From Neil Potter
Thanks Martin - Workmen recently dug up the path outside my driveway to install FTTC so I know it's there  My exchange goes live on 30th June - I can't wait!I have another question: I'm in the process of consolidating my TV, Telephone and Broadband into one bundle. The "BT Vision Unlimited" looks ideal.
7:19
Comment From Paul
Is there a estimated date that fast path will be available ?
7:19
Martin S.
Hi Kevin - Due to the structure of how fibre has been deployed, your line will either be FTTC or FTTP; there is no way to change your technology type. If you mean 'how do you move to the faster 80mb product (on FTTC)?', this can be done using the links on BT.com
7:19
Comment From Helen
I'm an existing customer.
7:19
Charles
No, 'fraid not, Paul.
7:19
Comment From Neil Potter
thinking about re-joining BT just for Infinity product(s)
7:19
Comment From Paul
existing customer here
7:20
Comment From Chris
I've recently ordered my Infinity package, installation is due the 22nd.
7:20
KerryG
Great to see you all on here... roll on the 22nd for you Chris
7:20
Comment From Kevin
Why are you fitting 2 separate items a modem and a wireless router? cant we have a combined unit, without the need for 2 adaptors and sockets its not the tidiest install
7:21
Comment From Chris
Regarding the Infinity installation, is it mandatory for the BT O/R Engineerer to have access to your PC?
7:22
Martin S.
Hi Chris - It is not mandatory, but we recommend allowing the engineer to show you on your own equipment your fantastic new speeds!
7:22
Comment From Simon
hi, im trying to setup port forwarding to my old draytek, as it has more powerful wirelelss capabaility then the bt homehub, is it possible
7:23
KerryG
Hi Simon - that sounds like a great question for the forum boards, the Draytek is not a BT product so we can go into detail here in this chat, but there will be lots of people who i'm sure can help in the forum.
7:24
Charles
Evening Kevin, for BT Infinity is based on thecurrent FTTC product offered by BT Openreach, which comprises the VDSL modem provided by Openreach and the Home Hub 3 provided by Retail. If/when Openreach move to supporting a single box solution, then we would look to moving to that. Openreach will shortly be trialling this.
7:24
Comment From Helen
I've already checked there's nothing interfering with the Hub.
7:24
Comment From Helen
I don't have a Hub3, both the one that is currently connected, and the old one I have in the box are Hub 2.
7:25
Comment From Chris
Yes, going from 3mb to an estimated 50mb+ is quite the upgrade, I would even be happy if it was merely a 10MB upgrade. - If I remember correctly FTTC is around(if not the same) price as standard broadband these days.
7:26
Charles
Helen - could you post your issue in the Bt Infinity forum and one of our mods will look into this for you.
7:26
Comment From Kevin
My install is planned for the 28th May my question is i have my master socket downstairs directly below the room i want my fttc modem installed is it possible to have the modem upstairs with the extension cable ?
7:27
Comment From Mike B
I have an istalation question. I understand that the modem for Infinity needs to be sited close to the BT phone socket. Am I right in thinking that the modem is then connected via a Cat 5/6 cable to the wireless router situated elsewhere in the house? Does this impact on the speed?
7:27
Comment From Helen
Ok charles, I will do..
7:28
Comment From Neil Potter
On the subject of Powerline Adaptors (PA's) - I have a unique setup here at home whereby I would need to utilise 4 x PA's. Are there any known performance issues sharing data, experiencing latency or dropped packets from Desktop PC's all connected via PA's at the same time?
7:28
Martin S.
Kevin / Mike B: The engineer can use an extension cable up to 30m long to help position your equipment where you want it - this should not affect your speed.
7:29
Comment From Eric Simpson
I have bt broadband .. I am currently getting 3M download. I have two "estimates" from the BT site. One says I should get between 10-17 ... the other which does some sort of check/diagnostic (and appears to be the real thing) says I should get between 1-4. We are meant to get Infinity next month. How would that impact me?
7:31
Charles
Hi neil - good question. I've found from experience that powerline performance is very much dependent on the adaptor manufacturer and your home environment, specifically how 'clean' your electrical spectrun is. All I can say is give it a try. That said, i would always recommend an Ethernet connection for the fastest and most stable speeds.
7:31
Martin S.
Hi Eric. You can find your predicted BT Infinity speed (if it is available on your line) at bt.com/infinity and entering your number into the availability checker
7:31
Comment From Simon
hi, really I'm just asking a tech question - can the bt home hub port forward?
7:32
Comment From Eric Simpson
Does my question pop up only when it comes up the queue?
7:33
KerryG
Hi Eric - Yes, they will flow in as they get answered - it helps to make the chat easier to read as the Q & As flow in a reasonable order.
Great questions coming through... lots more to get through...been a quick 33 mins!
7:33
Charles
Hi simon - I'm assuming you're talking about the Hub 3 (our latest Hub). Yes, it does support port forwarding. You can set this up via the configuration menu in your Hub. See instructions in your Hub user guide for how to do this.
7:33
Comment From Glynn
Will BT Retail be selling fibre-on-demand at an affordable cost for home users?
7:35
Comment From guilbo
Hello folks. I have a question. We often see on the Vision forum that users start having problems with their service on Infinity that they weren't having with ADSL. Do you know of anything that would cause this?
7:35
Martin S.
Hi Glynn, we are currently reviewing Fibre on Demand and have not yet announced any pricing or availability details.
7:36
Comment From Chris
How reliable is that checker by chance?
7:37
Comment From Paul (Heanor)
Also I am booked for installation on 22nd May
7:37
KerryG
Nice one Paul  You'll be enjoying super fast speeds then too
7:38
Charles
HI guilbo - I'm not aware of any technical issues for Vision customer regrading to Infinity. We have hundreds of orders go through each week. If the problem persists, I would suggest customers contact the Infinity helpdesk.
7:38
Comment From Neil Potter
Thanks for your reply Charles - If I could ask, the PA's you supply with the current BT Vision boxes are manufactured by Simpler Networks - would I need to purchase identical PA's from the same manufacturer for extending my network? Will BT Retail sell me these as an additional extra? This will be my last question - I feel I have been fortunate to have two answered already
7:39
Martin S.
Hi Chris - The speeds estimated in the checker are a very good indication of actual speeds, but we can only know the exact speed once installed.
7:39
Comment From Eric Simpson
it says not available yet. I am just frustrated because I get faster speed from my little Android phone using it as a hotspot. If there is a bottleneck somewhere in the system, would fibre really make a difference
7:41
Comment From Kevin
I have been given the estimate of 59.4Mb download 20.0Mb upload will this be accurate?
7:42
Charles
Hi neil - yes you should always stick to the same model for all your PA's. I am pretty sure that additional Vision PA's can be bought from the BT Shop, and these should be fine. I have had 70mbps out of mine! seewww.bt.com/shop
7:43
Martin S.
Eric - Generally fibre can make a very significant difference to overall speeds, though individual increases can't be guaranteed. If / when it becomes available on your line, the checker will tell you how much of a difference it could make to you.
7:43
Comment From Chris
I'm assuming it's based on the length of copper from my house to the Green Cab. - The exchange is 2miles~ away from me and the said Cab. Will this also effect my speed?
7:45
Charles
Hi Kevin - our estinmates are as accurate as we can make them, but your actual speed will depend on your underlying phone line speed. We will only know your true speed once Infinity is live - it will then train to your optimal line speed, which should be approx as shown by your prediction.
7:45
KerryG
Glad to see you all keeping Charles and Martin busy here... keep the questions coming in, we're in the last 15 mins now...
7:45
Martin S.
Chris - Yes, your speed is primarily affected by the total amount of copper between you and the exchange. With FTTC fibre products, the old copper between the exchange and the cabinet is replaced by fibre, meaning less copper overall and faster speeds.
7:45
Comment From Lewis
Why does DLM take so long to take interleaving off?
7:45
Comment From Neil Potter
Thank you very much for your time this evening Charles / Martin / Kerry. It's nice to see these types of events becoming more accessible to your customers and I for one feel I've got a lot from joining you all this evening
7:46
Martin S.
Thanks Neil - you're welcome!
7:46
KerryG
Great stuff Neil.... glad you've found it useful.
7:46
Comment From Chris
The Cab is 500-600 metres away from me, and according this graph the the BT estimated speed is just right on that.
7:47
Charles
Hi Lewis - DLM will apply interleaving only if it detects an ustable line. It will not apply interleaving unless it is warranted.
7:47
Comment From Kevin
I guess when i get my infinity installed a lot of sites and links will still be on dsl or adsl+ or even slower and the speed my end wont improve the speed there end ie my speed will depend on the site i visit and there upload speed for my download speed?
7:48
Comment From Dom
I am moving to BT infinity, but I had to order my line and then wait for it to be activated before ordering infinity. Is this a technical issue or a process at BT issue?
7:49
Charles
Evening Dom. It's a process issue - we can only provide Infinity once a Retail line is up and running.
7:49
Comment From William Sinclair
Hi guys. I've upgraded to Infinity 2 with an estimated max download of 49.5 Mbps however my IP profile hasn't budged from the Infinity 1 value of ~30. Any thoughts?
7:50
Comment From Dom
Thanks - this is a great service BT, keep it up!
7:51
Martin S.
Hi Kevin - yes, some websites that you visit may not be able to keep up with your superfast speeds! We aim to give you the best speeds at your end, but sadly there may sometimes be bottlenecks in the wider internet.
7:51
Charles
HI William - sorry for the delay in responding. Best thing to do is to reboot your Hub, then it should pick up the new speed. If not, contact the Infinity forum.
7:51
Comment From Lewis
What would cause an unstable line?
7:53
KerryG
@wiesiek @ Martin (not S) thanks for your questions, but as they're individual issues we can't pick them up as part of this chat. Please post in the forum and we can help.
7:53
Comment From guilbo
Apologies in advance for my ignorance. If Infinity is installed does the 'phone continue to use copper all the way to the exchange or does this also go over fibre?
7:54
Charles
Hi lewis - the most common cause is interference on your phone line, in which case DLM will moderate your BB speed until the line stablises. There'smore lot of info on this at the Infinity FAQs on BT.com
7:54
Martin S.
Hi Guilbo - good question - yes, the phone still uses the copper.
7:54
Comment From Paul (Heanor)
Will downloading from such as Xbox market place or apple store as examples max out the connection?
7:55
Comment From Kevin
Thanks to Martin, Kerry, and Charles for all your answers to the questions very much appreciated and a credit to BT Kevin
7:55

Hi everyone
Just a reminder that we have our Infinity Expert chat this evening at 7pm. If for any reason you can't make the chat, you can PM me your questions in advance and we'll try to include them. There will also be a replay available of the chat here on the same post after the event.

JacquiBT:
Hello everyone.
Thank for you joining our ‘Ask the Experts’ Live chat. I would like to introduce Dave, Sam and Emma who are our hub 4 experts and will be answering your questions tonight. I would like to invite you to ask your questions now.
7:03
[Comment From imjolly imjolly : ]
why are there no adsl stats available on the HH4
7:04
[Comment From DS DS : ]
evening all. Are the antennae omni directional?
7:05
Sean Donnelly:
Thanks for the question, Emma will respond
to that question Imjolly
7:05
JacquiBT:
Thanks DS, Dave will respond to your question now
7:05
Dave:
Hi DS, yes they are
7:05
[Comment From Steve Steve : ]
Are there any plans for new firmware on the hub 4 to bring new features?
7:06
JacquiBT:
Thanks Steve, Dave is answering that question for you
7:07
Dave:
Hi Steve - yes there are. There will be more information available about this - and any new features - before each firmware drop.
7:07
[Comment From Steve Steve : ]
why can you not opt out of BT WIFI on the home hub 4?
7:07
Dave:
Hi Steve - you should have no problem doing this through the Hub Manager
7:09
JacquiBT:
Some great questions coming through, the experts are typing up responses now
7:09
[Comment From DS DS : ]
Personal testing - Why is the 2.4GHz range less than the HH3 when at a distance from the hub, but better close up than the HH3?
7:10
JacquiBT:
Thanks DS, Dave is answering this now for you
7:10
[Comment From George George : ]
Will the 'Home Network' page show a HH4 instead of the Current image of the HH3?
7:11
JacquiBT:
Thanks George, Sam will answer that for you
7:11
Sam:
Hi George, the HH4 image will be displayed in place of the HH3 in the next firmware release
7:12
Dave:
Thanks again DS - you shouldn't find that, but this can depend on a lot of different factors in the home. I've found mine to be a bit better actually! But it should be pretty much the same for most customers.
7:12
Sean Donnelly:
Did you know the Hub 4 has Smart Setup?
Easy set up in just a few minutes. No CD or computer needed, it's all online and works on any device. Set up your Hub 4 router and access all your free extras like BT Cloud and BT Family Protection in just a few clicks.
7:12
[Comment From DS DS : ]
Is it possible for BT to allow us to move the BTWifi SSID's to another channel, leaving our own SSID on a less congested channel?
7:12
Dave:
Hi imjolly, sorry for the delay, Emma asked me to reply on her behalf. We have made the stats in the Hub manager simpler for customers to understand, we were reacting to feedback that it was too general for the wide range of customers and tech understandings.
7:12
JacquiBT:
Hi DS, Sam is replying to you now
7:14
[Comment From JamesS JamesS : ]
What speeds can I achieve over wifi, assuming I'm connected to 5ghz? Thanks.
7:14
Sean Donnelly:
Did you know the hub offers Easy Wireless?
Connect wirelessly by selecting your BT Home Hub connection on any compatible device and just push a button on the Hub and you're connected. It's that simple. No passwords needed.
7:14
JacquiBT:
Hi JamesS. Dave will reply to your question
7:14
Emma:
Hi imjolly, we have made the stats in the Hub manager simpler for customers to understand, we were reacting to feedback that it was too general for the wide range of customers and tech understandings.
7:15
Sam:
Hi DS, moving BT Wifi SSID's to another channel is not possible on the HH4. However, we are looking closely at the wi-fi SSID's the hub broadcasts to see whether we can improve this experience.
7:15
Dave:
Hi James, 5GHz maximum data transfer rate of 300Mb/s; this will tend to translate as an optimal actual speeds of up to 100 Mb/s - depending on lots of factors in your home
7:15
[Comment From George George : ]
Why did you remove the built in plastic wireless info tab with a card?
7:15
JacquiBT:
Hi George, Dave is going to reply to that question
7:16
Dave:
Hi George - this was part of the design process, we've tried to make it even easier for customers to find their wireless information. Now it's not integrated it's a little bit more accessible.
7:16
[Comment From thebennyboy thebennyboy : ]
I currently have the HH3 and would like to know what noticable difference it will make having a HH4 over a HH3? We use the ethernet ports and the wireless.
7:17
JacquiBT:
Hi Bennyboy. Emma is going to reply to that question.
7:17
[Comment From Paul Paul : ]
How much faster is the processor in the home hub 4, compared to previous versions? how will this effect my online experience?
7:18
JacquiBT:
Hi Paul. Sam will answer that for you
7:18
Sam:
Hi Paul, the processor is a staggering 3x faster compared to the HH3
7:19
[Comment From Guest Guest : ]
Although opted out of BT wifi the hub still shows as being active
7:19
JacquiBT:
Hi Guest, could we ask that you post this on the community so the moderators can pick this up
7:19
Sean Donnelly:
Did you know that the hub 4 offers Dual band frequency which makes for a more reliable wireless connection?
Smart dual-band technology reduces wireless interference and drop out’s giving you a reliable connection for all your devices.
7:20
[Comment From Guest Guest : ]
When you opt out of BT WIFI it appears to only opt out on the 2.4ghz channel and not the 5ghz channel. Are you looking into this?
7:20
JacquiBT:
Hi Guest. Dave will reply to your question
7:21
Dave:
Hi - thanks for this feedback, we'll definitely look in to it for you
7:21
Sean Donnelly:
Excellent questions coming through folks
7:21
Sean Donnelly:
Our experts are typing answers so please keep them coming
7:22
[Comment From Josh Josh : ]
Is it a known issue that the HomeHub 4 has problems identify the Xbox 360 as a media center extender when connected through a wired connection?
7:23
JacquiBT:
Hi Josh. Sam is replying to your question
7:23
[Comment From Winston Winston : ]
How much power does the home hub 4 use?
7:24
JacquiBT:
Hi Winston. Dave will respond to your question
7:24
Sam:
Hi Josh, we are aware of this issue. This is a problem with the Xbox rather than the HH4 but something we are reviewing together.
7:24
Emma:
Hi the bennyboy, the main advantages of the hub 4 are the faster processor (3 x faster) and 5 GHz wifi. There is no interference with 5GHz so you get better performance and as the range isn't as wide you dont have to share the bandwidth with neighbours etc. the hub still has 2.4 GHz so you still have the range you have withhub 3 too!
7:24
Dave:
Hi Winston, I am afraid there's no simple answer as it really depends on what features are in use. But the Hub 4 meets the latest Broadband Equipment Energy Code of Conduct targets for energy consumption.
7:25
[Comment From Mel Mel : ]
Why did you ignore your existing customers loyalty by charging them for a new hub, don't they pay enough already in their monthly fees?
7:25
JacquiBT:
Hi Mel, Dave will reply to your question
7:25
[Comment From Winston Winston : ]
How long did it take you to design and develop the home hub 4?
7:26
JacquiBT:
Hi Winston, Emma will reply to your question
7:27
[Comment From George George : ]
Will we get manual power save back?
7:27
JacquiBT:
Hi Gerorge. Sam will answer your question
7:28
[Comment From Jade Jade : ]
Does the home hub 4 support ip6 through a future upgrade?
7:28
Emma:
Hi Winston, It was about 2 years when we first started the project with the first ideas and concepts
7:29
JacquiBT:
Hi Jade. Emma will reply to your question.
7:29
Emma:
Hi Jade, thats something we are working on so yes something for the future
7:30
Sam:
Hi George. With regards to the manual power save feature, we have looked to make this automatic for all of our customers. However, you are able to change the brightness of the lights as an additional step.
7:30
Dave:
Hi Mel - we've made a lot of changes for our existing customers since the launch of the Hub 3 a couple of years ago. Our customer offer for the Hub 4 only £35 - a really big discount compared to the full price of £109! We've also created a range of recontracting deals that contain a Hub 4 for only the cost of delivery. If you're out of contract or in the last 3 months, you could take advantage of those offers as well. We really want all of our customers to be able to take advantage of these options!
7:31
Sean Donnelly:
Did you know the Hub 4 has a faster processor? Inside the BT Home Hub 4 router is our latest Broadband processor – the brains of your Hub. It allows you to pass information between connected devices quicker than ever. So if you are transferring files from one computer to another or watching a film streamed from another device, the BT Home Hub 4 won't slow you down.
7:31
[Comment From thebennyboy thebennyboy : ]
Our house has very thick stone walls and the wireless is weak in certain rooms. We have a few devices in our house that support 5Ghz Wi-Fi. Does the HH4 also work ok with home plugs that use your power cables to provide network connectivity?
7:32
JacquiBT:
Hi thebennyboy. Sam will respond to your question
7:32
[Comment From Calvin Calvin : ]
What future developments are in the works for home hub 4?
7:33

DS wrote:
Not many of my Q's are showing either. Could be busy I guess......
yeah I can tell, I know your quesitons are pretty good but if you notice that JacquiBT is deliberately choosing the questions she wants to go through. The whole chat is based around the fact that they have added 5ghz. I am appauled as I was hoping to at least ask one question.

Visit this forum often to view responses to your questions and the questions of other community members.

OOPS !!
I will repost the whole messaqge with the correct external URL's:
In general, the Trustsec design and deployment guides address the specific support for the various features of the 'whole' Cisco TS (and other security) solution frameworks. And then a drill-down (usually the proper links are embedded) to the specifc feature, and then that feature on a given device. TS 2.1 defines the use of ISE or ACS5 as the policy server, and confiugration examples for the platforms will include and refer to them.
TrustSec Home Page

I find this page very helpful as a top-level start to what features and capabilities exist per device:

The TS 2.1 Design Guides

DesignZone has some updated docs as well
http://www.cisco.com/en/US/netsol/ns982/networking_solutions_program_home.html#~bng
As the SGT functionality (at this point) is really more of a router/LAN/client solution, the most detailed information will be in the IOS TS guides like :

Ask the Expert: Single-Site and Multisite FlexPod Infrastructure

With Haseeb Niazi and Chris O'Brien
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Single-Site and Multisite FlexPod Infrastructure with experts Haseeb Niazi and Chris O'Brien.
This is a continuation of the live webcast.
FlexPod is a predesigned and prevalidated base data center configuration built on Cisco Unified Computing System, Cisco Nexus data center switches, NetApp FAS storage components, and a number of software infrastructure options supporting a range of IT initiatives. FlexPod is the result of deep technology collaboration between Cisco and NetApp, leading to the creation of an integrated, tested, and validated data center platform that has been thoroughly documented in a best practices design guide. In many cases, the availability of Cisco Validated Design guides has reduced the time to deployment of mission-critical applications by 30 percent.
The FlexPod portfolio includes a number of validated design options that can be deployed in a single site to support both physical and virtual workloads or across metro sites for supporting high availability and disaster avoidance. This session covers various design options available to customers and partners, including the latest MetroCluster FlexPod design to support a VMware Metro Storage Cluster (vMSC) configuration.
Haseeb Niazi is a technical marketing engineer in the Data Center Group specializing in security and data center technologies. His areas of expertise also include VPN and security, the Cisco Nexus product line, and FlexPod. Prior to joining the Data Center Group, he worked as a technical leader in the Solution Development Unit and as a solutions architect in Advanced Services. Haseeb holds a master of science degree in computer engineering from the University of Southern California. He’s CCIE certified (number 7848) and has 14 years of industry experience.

I would suggest you read this white paper which details the pros and cons of direct connect storage.
http://www.cisco.com/en/US/partner/prod/collateral/ps10265/ps10276/whitepaper_c11-702584.html   This paper captures all the major design points for Ethernet and FC protocols.
I would only add that in FlexPod we are trying to create a highly available solution and "flexible" solution; Nexus switching helps us deliver on both with vPC and unified ports.
NPV equats to end-host mode which allows the system to present all of the servers as N ports to the external fabric. In this mode, the vHBAs are pinned to the egress interfaces of the fabric interconnects. This pinning removes the potential of loops in the SAN fabric. Host based multipathing of the vHBAs account for potential uplink failures. The NPV mode (end-host mode) simplifies the attachment of UCS into the SAN fabric and that is why it is in NPV mode by default.
So for your last question, I will have to put my Product Manager hat on so bear with me.   First off there is no drawback to enabling the NPIV feature (none that I am aware of) the Nexus 5000 platform simply offers you a choice to design and support multiple FC initiators (N-Ports) per F-Port via NPIV. This allows for the integration of the FI end-host mode described above. I imagine being a unfied access layer switch, the Nexus team enabled standard Fibre Channel switching capability and features first. The implementatin of NPIV is a customer choice based on their specific access layer requirements.

Ask the Expert: Scaling Data Center Networks with Cisco FabricPath

With Hatim Badr and Iqbal Syed
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about the Cisco FabricPath with Cisco technical support experts Hatim Badr and Iqbal Syed. Cisco FabricPath is a Cisco NX-OS Software innovation combining the plug-and-play simplicity of Ethernet with the reliability and scalability of Layer 3 routing. Cisco FabricPath uses many of the best characteristics of traditional Layer 2 and Layer 3 technologies, combining them into a new control-plane and data-plane implementation that combines the immediately operational "plug-and-play" deployment model of a bridged spanning-tree environment with the stability, re-convergence characteristics, and ability to use multiple parallel paths typical of a Layer 3 routed environment. The result is a scalable, flexible, and highly available Ethernet fabric suitable for even the most demanding data center environments. Using FabricPath, you can build highly scalable Layer 2 multipath networks without the Spanning Tree Protocol. Such networks are particularly suitable for large virtualization deployments, private clouds, and high-performance computing (HPC) environments.
This event will focus on technical support questions related to the benefits of Cisco FabricPath over STP or VPC based architectures, design options with FabricPath, migration to FabricPath from STP/VPC based networks and FabricPath design and implementation best practices.
Hatim Badr is a Solutions Architect for Cisco Advanced Services in Toronto, where he supports Cisco customers across Canada as a specialist in Data Center architecture, design, and optimization projects. He has more than 12 years of experience in the networking industry. He holds CCIE (#14847) in Routing & Switching, CCDP and Cisco Data Center certifications.
Iqbal Syed is a Technical Marketing Engineer for the Cisco Nexus 7000 Series of switches. He is responsible for product road-mapping and marketing the Nexus 7000 line of products with a focus on L2 technologies such as VPC & Cisco FabricPath and also helps customers with DC design and training.

Hi Sarah,
Thank you for your question.
Spanning Tree Protocol is used to build a loop-free topology. Although Spanning Tree Protocol serves a critical function in these Layer 2 networks, it is also frequently the cause of a variety of problems, both operational and architectural.
One important aspect of Spanning Tree Protocol behavior is its inability to use parallel forwarding paths. Spanning Tree Protocol forms a forwarding tree, rooted at a single device, along which all data-plane traffic must flow. The addition of parallel paths serves as a redundancy mechanism, but adding more than one such path has little benefit because Spanning Tree Protocol blocks any additional paths
In addition, rooting the forwarding path at a single device results in suboptimal forwarding paths, as shown below, Although a direct connection may exist, it cannot be used because only one active forwarding path is allowed.
Virtual PortChannel (vPC) technology partially mitigates the limitations of Spanning Tree Protocol. vPC allows a single Ethernet device to connect simultaneously to two discrete Cisco Nexus switches while treating these parallel connections as a single logical PortChannel interface. The result is active-active forwarding paths and the removal of Spanning Tree Protocol blocked links, delivering an effective way to use two parallel paths in the typical Layer 2 topologies used with Spanning Tree Protocol.
vPC provides several benefits over a standard Spanning Tree Protocol such as elimination of blocker ports and both vPC switches can behave as active default gateway for first-hop redundancy protocols such as Hot Standby Router Protocol (HSRP): that is, traffic can be routed by either vPC peer switch.
At the same time, however, many of the overall design constraints of a Spanning Tree Protocol network remain even when you deploy vPC such as
1.     Although vPC provides active-active forwarding, only two active parallel paths are possible.
2.     vPC offers no means by which VLANs can be extended, a critical limitation of traditional Spanning Tree Protocol designs.
With Cisco FabricPath, you can create a flexible Ethernet fabric that eliminates many of the constraints of Spanning Tree Protocol. At the control plane, Cisco FabricPath uses a Shortest-Path First (SPF) routing protocol to determine reachability and selects the best path or paths to any given destination in the Cisco FabricPath domain. In addition, the Cisco FabricPath data plane introduces capabilities that help ensure that the network remains stable, and it provides scalable, hardware-based learning and forwarding capabilities not bound by software or CPU capacity.
Benefits of deploying an Ethernet fabric based on Cisco FabricPath include:
• Simplicity, reducing operating expenses
– Cisco FabricPath is extremely simple to configure. In fact, the only necessary configuration consists of distinguishing the core ports, which link the switches, from the edge ports, where end devices are attached. There is no need to tune any parameter to get an optimal configuration, and switch addresses are assigned automatically.
– A single control protocol is used for unicast forwarding, multicast forwarding, and VLAN pruning. The Cisco FabricPath solution requires less combined configuration than an equivalent Spanning Tree Protocol-based network, further reducing the overall management cost.
– A device that does not support Cisco FabricPath can be attached redundantly to two separate Cisco FabricPath bridges with enhanced virtual PortChannel (vPC+) technology, providing an easy migration path. Just like vPC, vPC+ relies on PortChannel technology to provide multipathing and redundancy without resorting to Spanning Tree Protocol.
Scalability based on proven technology
– Cisco FabricPath uses a control protocol built on top of the powerful Intermediate System-to-Intermediate System (IS-IS) routing protocol, an industry standard that provides fast convergence and that has been proven to scale up to the largest service provider environments. Nevertheless, no specific knowledge of IS-IS is required in order to operate a Cisco FabricPath network.
– Loop prevention and mitigation is available in the data plane, helping ensure safe forwarding that cannot be matched by any transparent bridging technology. The Cisco FabricPath frames include a time-to-live (TTL) field similar to the one used in IP, and a Reverse Path Forwarding (RPF) check is also applied.
• Efficiency and high performance
– Because equal-cost multipath (ECMP) can be used the data plane, the network can use all the links available between any two devices. The first-generation hardware supporting Cisco FabricPath can perform 16-way ECMP, which, when combined with 16-port 10-Gbps port channels, represents a potential bandwidth of 2.56 terabits per second (Tbps) between switches.
– Frames are forwarded along the shortest path to their destination, reducing the latency of the exchanges between end stations compared to a spanning tree-based solution.
    – MAC addresses are learned selectively at the edge, allowing to scale the network beyond the limits of the MAC addr

Ask the Expert: One Management with Prime Infrastructure 1.2

With Tejas Shah
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions from Cisco expert Tejas Shah on One Management with Prime Infrastructure 1.2 Combining the wireless functionality of Cisco Prime Network Control System (NCS) with the wired functionality of Cisco Prime LAN Management Solution (LMS), Cisco Prime Infrastructure simplifies and automates many of the day-to-day tasks associated with maintaining and managing the end-to-end network infrastructure from a single pane of glass. The new converged solution delivers all of the existing wireless capabilities for RF management, user access visibility, reporting, and troubleshooting along with wired lifecycle functions such as discovery, inventory, configuration and image management, automated deployment, compliance reporting, integrated best practices, and reporting.

Raun, please see my responses inline:
Can you go over the licensing method with Prime Infrastructure 1.2 please?
Raun, you can check out the following link for ordering guide at
http://www.cisco.com/en/US/products/ps12239/products_data_sheets_list.html
I currently have NCS and do NOT currently have LMS. I know I can move to Prime Infrastructure through Cisco Product Upgrade Tool. However, what I am confused about is do I still have to buy LMS to have LMS functionality in Prime Infrastructure 1.2?
==> Not at all. The converged product will give you basic management capability for routers and switches that LMS provided in this release. Feature/Functionality will keep on growing with upcoming releases.
If not, do the licenses I transfer into Prime Infrastructure 1.2 from NCS also work for devices to work under LMS?
==> Licensing is different than NCS or LMS. You don't have to transfer the license. Each install of Prime Infrastructure will have a unique UID string on which the licenses are based. A new license will be applied to the product.
Mean, can my currently 350 licenses be used for AP's as in NCS and routers in the LMS portion of Prime Infrastructure 1.2?
==> I would recommend getting a total count of your wired and wireless devices and match the right SKU based on that.
Hope this helps.. Let me know if you have any further questions,
Tejas
