Best practice for configuring virtual drive on UCS

Hi,
I have two C210 M2 Server with LSI 6G MegaRAID 9261-8i Card with 10 hard drives of each 135GB. When I tried the automatic selection for the RAID configuration, the system has created one virtual drive with RAID 6. My concern is what the best practice to configure virtual drive? Is it RAID 1 and RAID5 or all in one drive with RAID6? Any help will be appreciated.
Thanks.

Since you are planning to have UC apps on the server, Voice applications have specified their recommendations here.
http://docwiki.cisco.com/wiki/Tested_Reference_Configurations_%28TRC%29
I believe your C210 server specs could be matching TRC #1, where you need to have
RAID 1 - First two HDDs for VMware
RAID 5 - Remaining 8 HDDs as datastore for virtual machines ( CUCM and CUC )

Best Practice for configuring ZS3 storage

Hi Team
Can someone help me with the best way to configure data profile for a ZS3-2 storage which is mainly going to be used for oracle database and EBU application.
If we are planning to install ldoms os on storage lun then what data profile should be the best one.
Regards
AB

Without knowing more I would do the following, being very conservative;
Create too pools, with pool0 on controller0 and pool1 on controller1. This is to take advantage of both controllers DRAM, for better performance. Regardless of RAIDZ or RAID 1+0, I would do this.
I am assuming both trays are the same HHDs ( 900G?)
Make the first pool RAID 1+0, with 2 write SSDs and one READ SSD. I would use this pool for redo logs, and database files. Mounting via OISP or dNFS.
Make the second pool RAIDZ, with 2 write SSDs and one READ SSD, I would place my RMAN mount here, and any binary mounts and archive logs. Maybe DB files, if using partitioning. HCC is a great technology to use if you application will benefit from it.
Now for the relaity check!
9 times out of 10 method...
Realistic... just use RAIDZ on both pools. In reality RAID 1+0 generates more IOPS in the array and leads to more DB I/O wait time! It's true!
If you are headed to ECO I'll sit down and explain. short version, RAIDZ does less writes, which means better database performance.

Best practices for configure Rogue Detector AP and trunk port?

I'm using a 2504 controller. I dont have WCS.
My questions are about the best way to configure a Rogue Detector AP.
In my lab environment I setup the WLC with 2 APs. One AP was in local mode, and I put the other in Rogue Detector mode.
The Rogue Detector AP was connected to a trunk port on my switch. But the AP needed to get its IP address from the DHCP server running on the WLC. So I set the native vlan of the trunk port to be the vlan on which the WLC management interface resides. If the trunk port was not configured with a native vlan, the AP couldn't get an address through DHCP, nor could the AP communicate with the WLC. This makes sense because untagged traffic on the trunk port will be delivered to the native vlan. So I take it that the AP doesn't know how to tag frames.
Everything looked like it was working ok.
So I connected an autonomous AP (to be used as the rogue), and associated a wireless client to it. Sure enough it showed up on the WLC as a rogue AP, but it didn't say that it was connected on the wire. From the rogue client I was able to successfully ping the management interface of the WLC.
But the WLC never actually reported the rogue AP as being connected to the wired network.
So my questions are:
1. What is the correct configuration for the trunk port? Should it not be configured with a native vlan? If not, then I'm assuming the rogue detector AP will have to have a static IP address defined, and it would have to be told which vlan it's supposed to use to communicate with the WLC.
2. Assuming there is a rogue client associated with the rogue AP, how long should it reasonably take before it is determined that the rogue AP is connected to the wired network? I know this depends on if the rogue client is actually generating traffic, but in my lab environment I had the rogue client pinging the management interface of the WLC and still wasn't being picked up as an on-the-wire rogue.
Thanks for any input!!

#what's the autonomous AP's(as Rogue AP) Wired and Wireless MAC address?
it has to be +1 or -1 difference. If Wired MAC is x.x.x.x.x.05 and the wireless mac should be x.x.x.x.x.04 or 06. It is not going to detect if the difference is more than + 1 or - 1.
#Does the switch sees the Rogue AP's wired MAC on its MAC table.
Rogue Detector listens to ARPs to get all the Wired MAC info and forwards to WLC, It compares with Wireless MAC, if there is a +1 or -1 difference then it will be flagged as Rogue on wire. And the client that connected to it is also marked as found on wire.
Regards to Trunking, Only Native vlan matters per trunk link, just configure the right vlan as native and we're done.
It is not mandatory to keep the Rogue detector on Management vlan of wlc. It can also be on L3 vlan also as long as it can join the WLC to forward the learnt wired MACs.
So if we don't have +1, -1 difference on Rogues then you've to use RLDP which will work with your existing setup to find Rogue on wire. there's a performance hit when we use this feature on local mode APs.
Note: For AP join - AP can't understand Trunk, meaning if AP connected to Trunk it'll only talk to its native vlan irrespective of AP mode, however rogue detector listens to the Trunk port to learn MACs via ARPs from different VLANs and forwards to WLC using native vlan.

Best Practices for configuring ICMP from the outside

Question,
Are there any best practices or best recommendations on how ICMP should be configured from the outside? I have been cleaning up the rules on our ASA as a lot were simply ported over years ago when we retired our PIX. I noticed that there is a rule to allow ICMP any any and began to wonder how this works when the rules above are specific IP addresses and specific ports. This in thurn started me looking to see if there was any documentation or anything to help me determine a best practice. Anyone know of anything?
As a second part how does this flow on a firewall if all the addresses are natted? It the ICMP traffic simply passed through the NAT and the destiantion simply responds?

What are best practices for back up drives when they become full?

I've got an external hard drive that is now full. What do I do? Delete the oldest files on it, right? If so, do I delete the full backup and ALL the incremental backups since then? Do I have to do this manually now; isn't there a way to automate this?

The "usual" procedure is to move the oldest incremental backups from the hard drive to permanent storage media such as DVD.
However, if your backup drive is the same size as your main drive, then you could do incremental backups that delete files on the backup druve that have been deleted from the source drive. This prevents the drive from filling up with old and out of date files. However, if you need to maintain archives of even the incremental backups, then move the oldest to permanent storage media and delete them from the backup drive to free space.
Visit The XLab FAQs and read the FAQ on backup and restore for more information.

What is the best practice for formatting ext drives to be used by both Mac and PC users?

I have scanned what is available in the community about this issue and wondering if anyone has anything new to add. I need to create backup drives of department files (large photo and video) that both we Mac and the other PC users can access. The only consistent rec I see is FAT32, but that seems to have size limitations. Any other suggestions? Thanks.

The problem with FAT32 is that 4 GB or bigger files can't be stored. In this case, and as you have a Mac OS X version that supports it (10.6.5), you can use exFAT, compatible with Windows XP, Vista, 7, 8 and Mac OS X (10.6.5 and later).
To format a drive with exFAT, do this on a PC. If you do it on a Mac, a PC won't be able to read it. Apart from this, you will be able to store the files you need onto external drives, as exFAT hasn't got the limitations that FAT32 has.
Another option is to use NTFS, but you will need a third-party application on your Mac to be able to write on your external drives

Best Practices for Configuring Windows Server 2012 R2 for VM Performance

Good afternoon,
I've been told that VMWare has written a document or article on how to get the most performance out of an instance of Server 2012 R2 as a virtual machine. I was told this magical article has things like a checklist of features or services that can be turned off (such as tablet features) that will increase the performance/low overhead on the VM.
Can anyone help me find such an article?
Thanks,
Johnathan

Hello there,
There is no upgrade path from Server 2012 Essentials to R2. R2 is not an upgrade, it is a new build. Essentials does not upgrade easily, you will want to perform a migration of the server. This will require additional hardware. You
can possibly backup the 2012 Essentials, build a temp server on workstation hardware just to do the migration from, restore the backup to the new server and then perform the migration to R2.

Best practices for implementing OIM

We plan on putting OIM servers behind LB (hardware). When I develop OIM client I am required to specify OIM endpoint(s) via property java.naming.provider.url. In case of LB I'd specify a virtual host there. The question is what is the best practice for configuring LB - timeout, persistence, monitoring? I don think LB vendor is relevant, but just in case, I have a choice of F5 BigIP and Citrix Netscaler.
My understanding is that Java class tcUtilityFactory is supposed to be instantiated once (in a web client) and maintain the connection, but LB will close the connection after timeout is exceeded. So another question is if I want to use LB I have to take care of rebuilding connection when it is expired, or open/close connection every time tcUtilityFactory is needed. Any advice will be appreciated.
Thanks,
Alex

No i was not going to sync timeouts - just let it close connections after say, 5 min of inactivity. The reason is that performance data is horrible - from my desktop environment, initialization takes almost 9 sec, while reading data from OIM - only 150 milliseconds. I can't afford more than .5 sec on the whole OIM operation, as we are talking about customer experience.
Thanks,
Alex

Networking "best practice" for setting up a farm

Hi all.
We would like to set an OracleVM farm, and I have a question about "best practice" for
configuring the network. Some background:
- The hardware I have is comprised of machines with 4 gig-eth NICs each.
- The storage will be coming primarily from a backend NAS appliance (Netapp, FWIW).
- We have already allocated a separate VLAN for management.
- We would like to have HA capable VMs using OCFS2 (on top of NFS.)
I'm trying to decide between 2 possible configurations. The first would keep physical separation
between the mgt/storage networks and the DomU networks. The second would just trunk
everything together across all 4 NICs, something like:
Config 1:
- eth0 - management/cluster-interconnect
- eth1 - storage
- eth2/eth3 => bond0 - 8021q trunked, bonded interfaces for DomUs
Config 2:
- eth0/1/2/3 => bond0
Do people have experience or recommendation about the best configuration?
I'm attracted to the first option (perhaps naively) because CI/storage would benefit
from dedicated bandwidth and this configuration might also be more secure.
Regards,
Robert.

Option #4 (802.3ad) looks promising, but I don't know if this can be made to work across
separate switches.It can, if your switches support cross-switch trunking. Essentially, 802.3ad (also known as LACP or EtherChannel on Cisco devices) requires your switch to be properly configured to allow trunking across the interfaces used for the bond. I know that the high-end Cisco and Juniper switches do support LACP across multiple switches. In the Cisco world, this is called MEC (Multichassis EtherChannel).
If you're using low-end commodity-grade gear, you'll probably need to use active/passive bonds if you want to span switches. Alternatively, you could use one of the balance algorithms for some bandwitch increase. You'd have to run your own testing to determine which algorithm is best suited for your workload.
The Linux Foundation's Net:Bonding article has some great information on bonding in general, particularly on the various bonding methods for high availability:

Best practice for running multiple sites on 1 CF install?

Hi-
I'm setting up a new hosting environment (Windows Server 2008 Standard 64 bit VPS configuration, MySQL, IIS 7, CF 9)
Has anyone seen any docs or can anyone suggest best practices for configuring multiple sites in this environment? At this point I'm thinking simple is best, one new site in IIS for each client (domain) and point it to CF.
Given this environment, is anyone aware of any gotchas within the setup of CF 9 on IIS 7?
Thank you in advance,
Rich

There's nothing wrong with that approach. You can run as many IIS sites as you like against a single CF install.
As for installing CF on IIS 7, I recommend that you do the following: install CF 9 without connecting it to IIS, then installing the 9.0.1 upgrade and any hotfixes, then connecting CF to IIS using the web server configuration utility. This will keep you from having to install the IIS 6 compatibility layer that's needed with CF 9 but not with CF 9.0.1.

(Request for:) Best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC

Could you please share your best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC, that will be running on a new WinSrv 2012 r2 host server. (This
will be for a brand new network setup, new forest, domain, etc.)
Specifically, your best practices regarding:
the sizing of non virtual and virtual volumes/partitions/drives,
the use of sysvol, logs, & data volumes/drives on hosts & guests,
RAID levels for the host and the guest(s),
IDE vs SCSI and drivers both non virtual and virtual and the booting there of,
disk caching settings on both host and guests.
Thanks so much for any information you can share.

A bit of non essential additional info:
We are small to midrange school district who, after close to 20 years on Novell networks, have decided to design and create a new Microsoft network and migrate all of our data and services
over to the new infrastructure . We are planning on rolling out 2012 r2 servers with as much Hyper-v virtualization as possible.
During the last few weeks we have been able to find most of the information we need to undergo this project, and most of the information was pretty solid with little ambiguity, except for
information regarding virtualizing the DCs, which as been a bit inconsistent.
Yes, we have read all the documents that most of these posts tend point to, but found some, if not most are still are referring to performing this under Srvr 2008 r2, and haven’t really
seen all that much on Srvr2012 r2.
We have read these and others:
Introduction to Active Directory Domain Services (AD DS) Virtualization (Level 100),
Virtualized Domain Controller Technical Reference (Level 300),
Virtualized Domain Controller Cloning Test Guidance for Application Vendors,
Support for using Hyper-V Replica for virtualized domain controllers.
Again, thanks for any information, best practices, cookie cutter or otherwise that you can share.

Best Practice for SSL in Apache/WL6.0SP1 configuration?

Is it:
Browser to Apache: HTTPS

A getScheme should return HTTPS if the client is using HTTPS or HTTP if it
is using HTTP.
The option for the plug-in to use HTTP or HTTPS when connecting to Weblogic
is up to you but regardless the scheme of the client will be passed to
WebLogic.

Best practice for server configuration for iTunes U

Hello all, I'm completely new to iTunes U, never heard of this until now and we have zero documentation on how to set it up. I was given the task to look at best practice for setting up the server for iTunes U, and I need your help.
*My first question*: Can anyone explains to me how iTunes U works in general? My brief understanding is that you design/setup a welcome page for your school with sub categories like programs/courses, and within that you have things like lecture audio/video files and students can download/view them on iTunes. So where are these files hosted? Is it on your own server or is it on Apple's server? Where & how do you manage the content?
*2nd question:* We have two Xserve(s) sitting in our server room ready to roll, my question is what is the best method to configure them so it meets our need of "high availability in active/active mode, load balancing, and server scaling". Originally I was thinking about using a 3rd party load balancing device to meet these needs, but I was told there is no budget for it so this is not going to happen. I know there is IP Failover but one server has to sit in standby mode which is a waste. So the most likely scenario is to setup DNS round robin and put both xserves in active/active. My question now is (this maybe related to question 1), say that all the content data like audio/video files are stored by us, (We are going to link a portion of our SAN space to Xserve for storage), if we are going with DNS round robin and put the 2 servers in Active/Active mode, can both servers access a common shared network space? or is this not possible and each server must have its own storage space? And therefore I must use something like RSYNC to make sure contents on both servers are identical? Should I use XSAN or is RSYNC good enough?
Since I have no experience with iTunes U whatsoever, I hope you understand my questions, any advice and suggestion are most welcome, thanks!

2) having a multiple small serverpool consisting of less of number of guest vm I prefer option 1, as this gives me the greatest amount of resources available. I don't have to worry about resources in smaller pools. It also means there are more resources across the pool for HA purposes. Not sure if this is Official Best Practice, but it is a simpler configuration.
Keep in mind that a server pool should probably have up to 20 servers in it: OCFS2 starts to strain after that.
