<FONT COLOR="#000000">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. </FONT><BR>

<FONT COLOR="#000000">Our requirements are: </FONT><BR>
<BR>
<FONT COLOR="#000000">1 - Enable running virtual machines to be stored on storage device with adequate performance between host server and storage device.</FONT><BR>
<FONT COLOR="#000000">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.</FONT><BR>
<FONT COLOR="#000000">3 - Serve as a backup device for remaining servers in rack.</FONT><BR>
<FONT COLOR="#000000">4 - As much bang for the buck! disk storage capacity as possible that budget allows.</FONT><BR>
<FONT COLOR="#000000">5 - would be nice if solution could scale easily as demand for capacity grows. </FONT><BR>

<FONT COLOR="#000000">What product are you using for virtual machines ?</FONT><BR>
<BR>
<FONT COLOR="#000000">I would suggest if you are "small budget" then a FC SAN is pretty much out so for VM's that leaves you ISCSI or NFS, both will give you good performance over GigE however (depending on the storage you decide to go with) NFS may give you some more flexibility at the filesystem level. </FONT><BR>

<FONT COLOR="#000000">Thanks for the advice and the link you provided. The inquirer url shows the exact device we have been quoted on, the given price includes 1 x 100GB and 6 x 750GB Seagate SATA Drives. At the moment we are undecided on the SAN VS NAS, what is your opinion on both considering we want to run virtual machines on them. Also if we went for the "Intel Storage Creek 2" what OS flavor would you recommend? </FONT><BR>
