Freenas is FreeBSD based software appliance (iso distrubution) and will not be on Centos. You mentioned Xenserver 6.2 and KVM which one? Both are hypervisor software, you cant use both ( technically yes, recommended no) you also have 100 Mbps nics which will cause some performance issues. Freenas is using ZFS file system which needs to be tweaked heavily for NFS to work with, (legacy file system UFS is also available but they will drop supporting it in near future) you mentioned XCP I assume It is Citrix Cloud Platform and it is not a hypervisor, CS management server needs 4 GB memory 500 gig hd and thats all you need, no need for performance or ssd hds on that machine, I dont understand the need for iscsi hds for CS mgmt server, nothing happens on that server. Primary freenas will need more than 2 nics given that you have 10 tb space assuming you will need more than 160MBps bandwith ( 80MBps each with MPIO with ISCSI and not using NFS which is not capable of MPIO, but bonding is available for NFS)
There are a lot of things wrong with your setup here, you cant deploy Freenas with ZFS using NFS unless you turn off syncing for that NFS dataset otherwise it works but you get 10MBps write speed which is ridiculuous really and if you turn off syncing you better have some good UPS connected to it otherwise you may end up with corrupted file system ( Not ZFS itself but NFS dataset may get corrupt) You said high on IO for primary server but if you dont have the bandwith? with 2 Nics what good is it? even one of your hd may fill that bandwith really quickly... Big or small you cant deploy this...
