Our Budget is Max $25k, at the moment we have 3 x VMware ESX Servers
with each hosting 6-8 VM's. In the near future we would like to add a
dedicated box for Xen VM's as well, the rest of the rack consists of 4
Linux servers and 2 Windows (exchange + Blackberry). IMHO we are not
running any really IO intensive applications on any of our VM's at the
moment, but we do have a plan to create an additional Linux VM as a
secondary mail server running exim, clam, mailwatch, mailscanner, and
writing all to a MySQL Database, our current load on the mail is around
15 000 - 20 000 messages a day.
Our requirements are:
1 - Enable running virtual machines to be stored on storage device with
adequate performance between host server and storage device.
2 - Ability to move running VM's off a Baremetal ESX/Xen Server onto the
storage device temporarily should an ESX server need to be brought down
for maintenance or fail etc.
3 - Serve as a backup device for remaining servers in rack.
4 - As much bang for the buck! disk storage capacity as possible that
5 - would be nice if solution could scale easily as demand for capacity
