What HW RAID controller to use with Dell Optiplex 330 running vmware esxi 4? I found e.g Adaptec RAID 2405 is ESXi 4 compatible but I'm not sure whether it will work in PCIe 16x slot as I red sometimes desktop PCIe are "graphic card only". Thanks
I've never heard of Desktop PCI-E slots being "graphics only". We've got some "servers" at work that are built with desktop boards, and we've put Adaptect cards into them with no issues.
You can pick up a cheap server, I've got a Proliant ML 115 G5 (Quad core Opteron at 2.1GHz, 4GB ECC DDR2), which I bought a year ago for £200 total. With a decent controller (like Adaptec), it could be a nice little virtualisation box.
