Hello,

Which MSA are you using, if it is a MSA500, MSA1000, 1500 then you can use that as shared storage. If you use a MSA30 or MSA50, then they can not do the shared storage thing for ESX. As for disk space, you need to consider the following:

size of VMDK + size of RAM + size of VMDK (snapshots) + 512MBs of sundry files

The above gives a good estimate of how much space each VM needs.

Best regards,
