Thank you for the reply.
I posted the message looking for input from others who might have consolidated in this way. Everything you said are good points and those are all things I've considered.
Yes, I'll have backup hardware of course and backups of the VM's as well. However, you're right, I should have mentioned that these are individual ESXi blades and in different network LAN's. Doing separate LAN's on the single box is not a big deal and all of the VM's perform wonderfully off of the FC. Since everything is AMD based, it should not be a problem moving from one to another.
One thing I wondered is something you mentioned, that this number of VM's might not perform well on local disk. While I can run as many VM's as the box could handle, I think you are right that I would have to keep them on FC storage in order to continue getting good performance.
I guess you've confirmed everything I was wondering about. I just wanted a little input to know if I covered that bases.
Thanks.
