I'm considering a setup for a client.
Here's the hardware I'm considering:
I need to run two VM's for MS SBS 2008 Premium. For those who don't know it, that means DC, AD and Exchange on one server and SQL 2008 along with a custom intranet system on IIS on the other server.
From what I've read, NFS should serve as an acceptable solution, thus enabling me to simply have the vmdk's placed on the NFS file shares.
I would run one VM on each PowerEdge, and then one ReadyNAS for each server, with maybe 1 TB allocated to each server and then 1 TB extra for snapshots.
I plan on using the the snapshot facility on the readynas to simply backup the vmdk's, and then have those snapshots be copied to some external USB-harddrives that can manually be transported off site.
I want the setup to be prepared for HA with ESX SMB Edition so each NAS would need to have two shares, that would each be mounted as datastores in VMware AND I'm thinking I could use rsync to replicate between the NAS'es so that each would always have a copy of the other NAS.
OK let me try and illustrate.
[VM-Host1].VM1 --runs from--> [NAS1].Share1 --rsync to--> [NAS2].Share2 [VM-Host2].VM2 --runs from--> [NAS2].Share1 --rsync to--> [NAS1].Share2
I'm also considering a Dell PowerVault NF500 with WSS2003R2 and an Iomega Storcenter IX4-200d or maybe the NetGear ReadyNAS PRO Business with 6 x 1 TB disks in 3 x 1 RAID 5, 2 x 1 RAID 1 and one spare. With essentially two spindle sets in each NAS I could maybe separate some stuff inside the VM's, maybe with page file on one spindle set and sql-db or exchange-db file on the other.
Would this work as I hope? Anyone with some hands on experience, could you maybe offer some advice. Would be much appreciated.
