Hi guys,
just wondering if someone could advise...
I'm running a small citrix xenserver pool with 4 servers and some 20 or so virtual machines. Currently I am using a TS253 with 2 1TB hard drives (RAID-1) and NFS4 for the virtual machines' disk storage. However, the disk storage is actually a bottleneck. The So I'm thinking of getting a new server using SSDs in a RAID configuration.
My question is now related to the particular access pattern for a virtual machine... The virtual machine disks are obviously simply huge files which get once allocated and then change, possibly many times on the same block, does a normal consumer SSD handle such a pattern correctly? Can a 2 disk solution with RAID-1 provide enough redundancy or would I best go for a RAID-6 4 disk solution?
Thanks,
Andres
