I have an x346 server with 3 x RAID 5 73GB U320 HDD's running ESXi with 2 VM's on it.
1 VM is an exchange server running IIS and SQL2008. The other is an applications VM running IIS.
I have another 3 x 36GB U320 HDD's and want to put these into the server as more storage, possibly on RAID 5.
What is the best way to add these drives? Is it possible to have 2 RAID 5 disk arrays? I've not had a play yet with putting the drives in.
As the 36GB drives will be used for storage which will be backed up off-site, which RAID option would be the best? I would like redundancy, but as this will be file storage ONLY (no DB, OS etc.) a backup may be sufficient.
