Hi, I'm looking to build a virtualized web hosting server environment accessing files on a hybrid storage SAN. I was looking at using the Sun X-Fire x4540 with the following configuration:
- 6 RAID-Z vdevs with one hot spare each (all 500GB 7200RPM SATA drives) - 2 Intel X-25 32GB SSD's as a mirrored ZIL - 4 Intel X-25 64GB SSD's as the L2ARC. - De-duplification - LZJB compression The clients will be Apache web hosts serving hundreds of domains. I have the following questions: - Should I use NFS with all five VM's accessing the exports, or one LUN for each VM, accessed over iSCSI? - Are the FSYNC speed issues with NFS resolved? - Should I go with fiber channel, or will the 4 built-in 1Gbe NIC's give me enough speed? - How many SSD's should I use for the ZIL and L2ARC? - What pool structure should I use? I know these questions are slightly vague, but any input would be greatly appreciated. Thanks!
