Hi guys;
I had an AIO w/ZFS on ESXi 5.1 a little while ago, then split it up into a fileserver machine running on bare metal and a XenServer 6.2 VM machine. All VMs were stored on the filesever, along with everything else for the business.
Now I need to move back to a single machine. I do remember reading somewhere on [H] - a post by Gea perhaps? - that XenServer wasn't well suited to an AIO setup due to really poor I/O performance due to the VM I/O being routed through the dom0, or something like that. I can't find reference to it now.
I'd like to stick with XenServer if possible as I don't really want to convert 20-odd VMs back to ESXi... but if the performance delta is huge I will. I also simply prefer XenServer 6.2, but performance is more of an issue than preference here.
Anyone have any input?
