I'm looking at virtualising some of our infrastructure in order to allow for more resiliance and future expandability.
We have successfully virtualised on single servers with Direct Attached Storage and are now looking for a more future proof solution using a high powered host (or two) and a SAN (or two).
I'm thinking that the host machine will probably be an HP ProLiant DL360 G7 (all of our exisiting infrastructure is HP).
Unfortunately, I am new to the world of SANs. From what I can see, the Buffalo Terrastation III is all I would need in order to setup an iSCSI SAN for VMWare to use. However, I'm a little reticent to go that way as it's a bit too "entry level" for my liking. In particular I would be very keen for more redundancy, power, networking, etc. I'm also very aware that you "get what you pay for".
Therefore, can anyone reccommend equivalents from the big boys? HP/IBM? I have searched high and low on the HP site and seen many options but am struggling to work out if it is all the hardware I will need. Some options appear to need separate controllers from disk enclosures, etc.
