This week I almost bought a second-hand SAN for my two ESX servers I run here – nothing fancy just a MSA1000. Unfortunately, the system was purchased a while back when HP/Compaq were using Emulex Cards. It took a while for the seller to get back to me with their version numbers. With all this “re-badging” of SAN kit that goes – its very difficult to work out what type card you actually have what with a combination of Emulex code numbers and HP/Compaq code numbers. It turned out that they were HP versions of Emulex cards – and VMware does NOT support them. So its back to the drawing board I guessâ€¦ From what I gather from the support forum Emulex cards do not have a great reputation in the VMware communityâ€¦
Anyway, in my research I stumbled across a useful document – that goes beyond the normal what’s supported/not supported – it also covers the intricacies of SAN Booting. Previous versions of ESX did not support booting from the SAN – indeed it was a install recommenedation to disconnect from the SAN if you intention is to install to local drives. That recommendation still stands – but SAN booting is now an option in 2.5. I think its geared up for people who have gone down the Server Blade route and wish not have anything installed locally to the Blade for ease of recovery/cloning. Anyway, you might find this document interesting:
Meanwhile, I am very close to finishing my guide on VMware’s P2V. I’m up in Glasgow, Scotland teaching Citrix this week – so that is on hold. When I come back I am going to add a quick over of LeoStream’s P>V. As of yet I have no success in obtaining an evaluation version of PlateSpin.
When I finished the P2V guide I will post it to my website – and let you all know. That will more or less end the development on VMware ESX/vCenter/P2V – from then on I will be refining/tidying/updating my documents.
I hope shortly to have a second co-teach arrange and finally get signed off as a certified instructor for VMware. I didn’t think it would take this long – but politics has played a major part in some of the delays
