Emulex OneConnect OCe 10100 and VMware 4.1iU2

I have checked the HCL, forums, Emulex site and cannot find any information on thw Emulex OneConnect OCe 10100. My dilema is that the customer has many Dell 710 with this card. I cannot find it on the HCL, it causes VM and host lockup in the hardware iSCSI persona, but works with software iSCSI. The upgrade path to vSpere 5 may have issues, and if it is not on the HCL, VMware will not support.

I got a response from Mike Brown referencing http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1027206. Points go to Mike Brown for the first and quickest response.

I also got an explanation from Andreas about the OCe 10100 being a device family rather than a specific card and also referencing this link http://downloads.vmware.com/d/details/dt_esxi50_emulex_be2net_413340/dHRAYndld3diZHAlJQ==

I think I will have an answer to this in a few days and will post the results.

HCL Issues, VMware Update Manager, and Migrating a vDS switch when using etherchannel

Not much going on this week, chasing down a HCL issue with a CNA card in a Dell server. Gathering information to determine if the server was shipped that way, or if was a third party install. Basics and best practices have to be known to establish a baseline, else you do what you want and who knows what you get.

Also a great blog on VUM at http://www.anotherdayinit.com/2012/02/21/vmware-update-manager-patching-a-vsphere-host/

and Migrating to a VDS switch when using etherchannels from Duncan Epping at http://www.yellow-bricks.com/2012/02/21/migrating-to-a-vds-switch-when-using-etherchannels/

Passed VCP 5

I passed the VCP 5 on Monday evening. I started preparing in November 2011 and planned to take the test in December, but I was on R&R from Afghanistan and I got busy with family stuff. I started preparing again the middle of January 2012. My take on the exam, was that you had to know your performance and troubleshooting, as well as the new features. Most of it was vSphere 4 knowledge. If you know the 4 product well and how to work with it, plus learn the new features and how they work, you should be fine. I have not worked with the vSphere 5 product, but have a lot of experience with the,2,3,and 4 versions. Read the blueprint, read all of the vSphere 5 pdfs, brush up on the networking, performance and troubleshooting, new features, and be ready for the scenarios. Great exam.

vCenter Design Considerations with VUM, SQL, and SRM, Your thoughts?

So I was having a discussion with a few fellow VMware dudes, and we were discussing the vCenter installation methods. One train of thought is to install vCenter, VUM, SQL 2008,, and SRM on 1 VM with 2 vCPUs, 4 GB of memory an a 100 GB drive, Monitor for performance and adjust as required by analyzing the performance data. I have alwbeen doing installations this way lately without issue. I have also done installations on dedicated SQL boxes \ VMs. I have gotten good performance out of the environment with having all services on a single VM. In larger environments of 20 or more hosts and 300 + VMs, I have used a dedicated SQL server. The SRM documetation recommends a separate server for the SRM installation, but I have not seen any issues with it on the same box, and there was not any performance degradation in an environment of less than 200 VMs.

Also in many environments, there is not a DBA to manage the SQL box, and I have had to become the resident expert on-site. Some customers feel more comfortable with single instances. Another train of thought was to separate SQL, VUM and SRM on separate VMs, and while I am not opposed to that, I would like to know what you have been doing in real world scenarios throughout your experience in the industry.

I know what documentation states, but sometimes we have to think outside the box and push the envelope. I remember in the ESX 2 days, some thought that it was too much to put all your eggs in one basket, and the thought of virtualizing SQL and Exchange, much less vCenter was a crime.

So what do you say based on experience and time in the field?
