Lefthand will also sell you their software without hardware - SAN-IQ. Don't know the IOPS rating for their stuff either, but we bought our two Lefthands before HP bought them - they're Dell 2950's with 6x750gb each. They work just fine for the load we put on them, which is mostly our 2tb file server, which a Win2k3 box we virtualised on ESX3.5
