We're looking for a commercial quality, heavy duty RAID unit that we connect into a DB server via fiber. More interested than anything to know who is making the highest end RAID units available in the market as of late.
High end, or at least well known is EMC. They make the the dual-controller EMC CLARiiON AX150. It runs over fiber of Gig in an iSCSI configuration. It works with all OS's with iSCSI initiators from MS and Linux, also supports VMware ESX 3.0.
