Should Data Center WAE point to GLBP IP address?

I will be connecting a Data Center WAE-7341 to a distribution layer made up of two 6509s. The 6509s currently have a /30 L3 connection between the two of them on routed ports. I plan on changing that to a /29 SVI connection (changing the ports to switchports) and connecting the 7341 to one of the 6509s' ports configed in the same vlan. (Eventually I'll connect a second, redundant 7341 to the other 6509, same vlan, for redundancy.)
Should I make the connection between the two 6509s a GLBP config, and have the 7341's gateway the virtual IP - but still config WCCP router-list to point to the real IP address? Or should I keep GLBP out of the picture by not configuring it, and pointing the 7341's gateway to the IP address on the 6509 it is connected to - the same as the router-list IP?

Registration
Do NOT use a virtual gateway address (HSRP, VRRP, GLBP)
If you dont specify an IP in the router list is will use the default gateway by default.
If you do use the VIP as the default route, you may see a negative influence when the edge fails over. The DRE cache will be lost as the connection gets reset and initiated on the 2nd WAE. unless your connected to both A and B side routers from Each WAE.

WAE inline or WCCP on data center

Hi all,
Is WAE(674)inline mode fine for data center or should I go for WCCP?
Any idea about throuput of inline adaptor?
Thanks

Hi Nomair,
I usually start with WCCP in the DC due to the fact that you are limited to intercepting on 2 links with the inline card currently and most DC scenarios have requirements of using more then 2 links (or routers).
Thanks,

Windows Server is Windows, but the Server OS. SharePoint runs on top of supported Windows Servers editions (see http://technet.microsoft.com/en-us/library/cc262485.aspx).
SharePoint Server is 64-bit only (trial:
http://technet.microsoft.com/en-us/evalcenter/hh973397.aspx), although Designer does have a 32-bit edition (full product:
http://www.microsoft.com/en-us/download/details.aspx?id=35491).
You will need the capability to run 64bit VMs. Minimum recommended all-in-one VM for SharePoint is to allocate 24GB of RAM, but you can get away with as little as 12GB (I wouldn't go below that). Because of this, it generally rules out 32bit OSes as a virtual
machine host.

Remember that you can continue the conversation in the Data Center Community, under the subcommunity Unified Computing, shortly after the event. This event lasts through August 1, 2014. Visit this forum often to view responses to your questions and the questions of other Cisco Support Community members.

Hi Ramses,
I have dozen questions but will try to restrain myself and start with the most important ones :)
1. Can cables between IOM and FI be configured in a port-channel? Let me clarify what I"m trying to achieve: if I have only one chassis with only one B200M3 blade inside, will the 2208 IOM and FI6296 allow me to achieve more than 10Gbps throughput between the blade and the Nexus 5k? Of course, we are talking here about clean ethernet environment.
B200M3 --- IOM2208 --- 4 links --- FI6296 --- port-channel (4 links) --- Nexus5548
2. Is it possible to view/measure throughput for Fibre Channel interfaces?
3. Here is one about FlexPod: I know that in case of vBlock there is the company that delivers fully preconfigured system and offers one universal support point so customer don't have to call Cisco or VMware or storage supports separately. What I don't know is how it works for FlexPod. Before you answer that you are not sales guy, let me ask you more technical questions: Is FlexPod Cisco product or is NetApp product or this is just a concept developed by two companies that should be embraced by various Cisco/NetApp partners? As you obviously support Datacenter solutions, if customer/partner calls you with are FlexPod related problem, does it matter for you, from support side, if you are troubleshooting fully compliant FlexPod system or you'll provide same level of support even is the system is customized (not 100% FlexPod environment)?
4. When talking about vCenter, can you share your opinion about following: what is the most important reason to create the cluster and what will be the most important limitation?
5. I know that NetApp has feature called Rapid Clones that allows faster cloning than what vCenter offers. Any chance you can compare the two? I remember that NetApp option should be much faster but didn't understand what is actually happening during the cloning process and I'm hoping you can clarify this? Maybe a quick hint here: seems to me it will be helpful if I could understand the traffic path that is used in each case. Also, it will be nice to know if Vblock (i.e. EMC) offers similar feature and how it is called.
6. Can I connect Nexus 2000 to the FI6xxx?
7. Is vBlock utilizing Fabric Failover? Seems to me not and would like to hear your opinion why.
Thanks for providing us this opportunity to talk about this great topic.
Regards,
Tenaro

Layer 2 connect - data center web hosting

hi, i need your help!!
i have data center with the nexus 7000 , i have servers connecting to the cisco 7000 with web servers. my company do hosting for customers.
the poing that we have shared resources like vmwares on blades and so on.. mean that the ports of the blade are connecting physically to the nexus 7000 with trunk and vlans for every customers.
my nexus connecting to FW than to WAN stiches than to Routers connecting to the internet so if i asked to to hosting from the internet its easy.
the problem is now i have cusomer that wants to connect his switch over the wan directly to his area at my datacenter.... we make for him servers that are the same like his servers with the same subnet and he makes replications...
he dont have router, he connect his switch over wan provider at layer 2 to me..
should i connect him direcly to my nexus??? with his vlan?? should i need other solution like eompls??? what is the safest way to connect him with layer 2.. and i repeat the problem that our servers are shared between many customers - the same nexus ports, please help!!

Hello,
1.PIX is the precursor to the ASA so at this point the ASA is probably a better choice since it'll be around longer plus I'm sure they have beefed up the base hardware compared to the pix.
2.Your external router is dependant on how much traffic your going to be dropping into your hosting site. A 7200 series router is a fairly beefy router and should be able to handle what you need if your looking.
3.One of the nice things about the 6500 is you can put a FWSM and segment all your different hosting servers to provide a more granular network control.
I don't have any case studys but will look around and post them if I find some.

Single CAS NameSpace in Multi-Data Center Model With Exchange 2013

Hi
We are in process of transitioning from Exchange 2007 to Exchange 2013. Our Exchange 2007 infrastructure is as follows:
2 Data centers (DC 1 and DC 2). Both with active user population. Both have their own direct Internet Connectivity
Standalone Exchange 2007 mailbox servers in each data center
Load Balanced CAS (HT co-located) servers using Hardware Load Balancers in each data center. Load balancers are configured with VIP and FQDNs (LoadBalancer1.Com and LoadBalancer2.com)
Currently No access allowed from Internet except ActiveSync (No OWA or OA)
Outlook anywhere is disabled in Exchange 2007 organization but once mailboxes will be moved to Exchange 2013, OA will definitely be used – we will provide OA on Intranet as well as Internet
All the internal URLs including Autodiscover point to VIP (Load Balancer IP)
Autodiscover is not currently published on Internet, but we have a plan to publish it now once Exchange 2013 is introduced
We want to keep a single CAS NameSpace BYOD.ABC.Com for our ActiveSync and OA (and not going to allow OWA) access from Internet. We want to have Split-DNS for our new Exchange 2013 infrastructure due to
the simplicity it brings. So we are going to use one name BYOD.ABC.Com from the Internet. We have GSLB that provide Fault Tolerance and Geo-Load Balance to external requests coming from Exchange clients, between two data centers. When we will
install new Exchange 2013 servers, they’ll be part of new VIP so:
In a 2 data center model, can we name our internal VIPs same in both data centers (i:e BYOD.ABC.Com) as we have decided to go with Split-DNS? Do you see any caveats to this strategy
If the above strategy will not work, what are the alternate approach(es).
If we configure same names for the VIPs in both data centers, it will mean that the Autodiscover SCPs for all the Exchange 2013 CAS objects (and Exchange 2007 CAS objects during co-existence) will point to BYOD.ABC.Com. This should not be a problem for
AD joined systems as they’ll find and contact Autodiscover endpoints in their own sites (based on Keywords attribute that tells which AD site SCP belongs to) –
Please correct me if this is wrong.
If we configure same names for the VIIPs in both data centers, this also means that we have to configure BYOD.ABC.Com on External as well as Internal URLs on all the Exchange 2013 servers across both the data centers – Wouldn’t that be a problem – in terms
of loops during CAS-CAS Proxy/Redirection?
If we configure different names of the VIPs (say BYOD1.ABC.Com and BYOD2.ABC.Com), how will the Outlook Anywhere requests be handled in both data centers. The OA requests from DC1 will expect the Certificate Principle Name to be BYOD1.ABC.Com and requests
from DC2 will expect the Certificate Principle Name to be BYOD2.ABC.Com. How to get this stuff working. As far as I know, OA expects CPN to match with it’s name.

Data Center Network Design

I'm looking at a couple options for a small network in a data center. I seem to be getting hung up on all the different options. One of the options I'm looking at is end or row using both 2960Ss and Blade Center chassis switches with each physical server dual homed into a 2960, each ESX server dual homed into a blade switch and each of the switches with a Layer 2 10Gb uplink (20 total with etherchannel) to one of two 4900Ms. The 4900Ms would then have a layer 2 uplink between them to accomodate VLANs that span the access layer switches. This would be an inverted U topology. That's simple enough, and maybe that is where I should leave it, but there is the now available stacking feature of 2960s that has me wondering if there is another option available with dual homing a stack. Is there such a beast? Would it be better to stack 2960s, or even 3750s, so as to make each end of row with 2 redundant switches appear as one logical stack, and then uplink that stack to an aggregate multilayer switch such as a pair of 4900Ms? Or might that limit me to keeping VLANs within a stack and end or row?
thank you,
Bill

Hi Bill-
First, I personally would not use the 2960S for the data center, no matter the size. That switch was purposely built for user access and has some limitations. Also, depending on what you need to accomplish will determine your design. I recently did a design similar to what you are describing. We ended up putting 3750X's at the top of rack as a stack. This allows for etherchannel to your servers with both server NICs being active. From there we uplinked to a pair of 6509's in VSS. From a layer 2 point of view this was about as simple as it gets; 1 switch connected to another switch connected to a server. No spanning tree! If you can't afford stackable switches, you may want to look at routing at the top of rack. However you will lose functionality like moving VLAN's between racks, relying on server NIC software for active/passive links and the moving of VM's could be limited.

The beautiful curve drawn by LDPC code caught my eyes, but several points hardly built up user confidence.Some details should be submitted carefully, especially comparison with BCH codes. In my opinion, X-axis is exact error bit count and Y axis is frame error rate. Then, BCH comparison is a theoretical vertical line. LDPC code will be well described in a group of points.
Moreover, can Xilinx provide more codes with different rate to support flexible design?

Deploying Cisco Overlay Transport Virtualization (OTV) in Data Center Networks

Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about how to plan, design, and implement Cisco Overlay Transport Virtualization (OTV) in your Data Center Network with Cisco experts Anees Mohamed Abdulla and Pranav Doshi.

Hi Dennis,
    All those Layer 2 extension technologies require STP to be extended between Data Centers if you need to have multiple paths between Data Centers. OTV does not extend STP rather it has its own mechanism (AED election) to avoid loop when multiple paths are enabled. It means any STP control plane issue, we don't carry to the other Data Center.
    OTV natively suppresses Unknown Unicast Flooding across the OTV overlay. Unknown unicast flooding is a painful problem in layer 2 network and difficult to troubleshoot to identify the root cause if you don't have proper network monitoring tool.
   It has ARP optimization which eliminates flooding ARP packets across Data Center by responding locally with cached ARP messages. One of the common issues I have seen in Data Center is some server or device in the network sends continuous ARP packets which hits Control plane in the Aggregation layer which in turn causes network connectivity issue.
The above three points proves the Layer 2 domain isolation between data centers. If you have redundant Data Centers with Layer 2 extended without OTV, the above explained layer 2 issue which happens in one Data Center carries the same failure to the second data center which creates the question of what is the point of having two different Data Centers if we can not isolate the failure domain.
OTV natively supports HSRP localization with few command lines. This is a very important requirement in building Active/Active Data Center.
Even though your question is related to L2TP, OTV deserves the comparison with VPLS and those comparison will also be applicable for L2TP. The below link explains in detail...

Please shed some light on Data Center design

Hi,
    I want you guys to recommend what the design should be. I'm familiar with HP blade system. Let me clarify the existing device.
1. HP Blade with Flex Fabric. It supports FCOE.
2. MDS SAN switch for the storage
3. Network Switch for IP network.
4. HP Storage.
    HP Blade has 2 interface types for IP Network(Network Switch) and Fiberchannel(SAN).
   What is the benifit for using Nexus switch and FCOE for my exising devices. What should be a new design with Nexus switch? Please guide me ideas.
THX
Toshi

Hi, Toshi:
Most of these chat boards have become quite boring. Troubleshooting OSPF LSA problems is old news. But I do pop my head in every now and then. Also, there are so many other companies out there doing exciting things in the data center. You have Dell, Brocade, Arista, Juniper, etc. So one runs the risk of developing a myopic view of the world of IT by lingering around this board for too long.
If you want to use the new B22 FEX for the HP c7000 blade chassis, you certainly can. That means the Nexus will receive the FCoE traffic and leverage its FCF functionality; either separate the Ethernet and FC traffic there, or create a VE-port instantiation with another FCF for multihop deployments. Good luck fighting the SAN team with that one! Another aspect of using the HP B22 is the fact that the FEX is largely plug and play, so you dont have to manage the Flex Fabric switches.

URGENT: QoS Design on Data Center MPLS - MediaNet Question...

Hello,
I am posting this in hopes I can get some guidance from anyone who has done this in the field. We have a large enterprise customer with 21 sites all around the world, they have Verizon MPLS and are experiencing QoS related issues on their WAN regarding Video/Voice. We have proposed remediating their network acccording to the Enterprise QoS SRND 3.3 and the new MediaNet SRND to account for Video and TP QoS (
http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND_40/QoSCampus_40.html )
Here is the problem/question that was proposed in our presales meeting and I honestly don't know where to look for an answer... I am not asking for anyone to design a solution for me, just merely point me in the right direction:
The Data Center has a ~40MB MPLS Connection ( full mesh ) into the cloud ( Verizon )
Site A has a 8MB connection
Site B has a 4MB connection
I know on the Service policy and the interfaces at SiteA and SiteB I can assign "Bandwidth xxxx" and use ~95% of the bandwidth to do queuing and shaping/policing ect. I am not concerned with SiteA and SiteB, that I think I can handle...
Question was posed from the customer, "How can we ensure at the DataCenter level the 40MB MPLS is "chopped" up so that only 8MB of the total speed goes to SiteA ALONG with an attached QoS policy designed for that specific site, as well as ensure only 4MB goes to SiteB with an attached QoS policy.
So I am looking for a way to allocate bandwith per site on the DC 40MB connection going into the cloud ( so that SiteB cannot use more than 4MB ) and attach a MediaNet specific QoS Service policy to that site. The customer does not have seperate MPLS circuits for each site, they all come into the DC on 40MB shared ethernet connection ( no VC, or dedicated circuits to other sites ).
Any thoughts on if this is possible?
Thanks!
Alex

It would be greatly appreciated if someone can correct this or improve it as I am still learning.
Please see the netflow graph from one of our routers using a similar policy as above.

Data Center Aggregation/Access SW Nexus

i have a design scinario for backup email data center, some difficulties faced when trying to match the requirements to Boxes.
the design required a Nexus 5548UP with addition to 2x Virtualized Data center switches, also it required 12 x CPU license for VM Virtual Network Switch. i suggested to add Nexus 1000 series but the consern is can i use it without adding Nexus 2k . if i have to use N2k and N1k what is the best configuration scinario?

Hi Shakeeb,
I don't understand your question very well, but I will try clarify some points.
You don't need a Nexus 2000 if you have enough ports available in your Nexus 5500, even if you will use nexus 1000v.
In this scenario what I recommend to you is connect the both Nexus 5548 each other and create a vpc with upstreams routers and downstream blades and storage.
