I'm curious about Lefthand SAN solutions from HP. People from Dell have told me that Lefthand SAN's require at least two nodes and data must be mirroring between them so capacity is a half less compare to other SAN technology (e.g.Equal Logic). Is it true? Can a HP lefhand SAN be used as a stand-alone storage server with full RAID function (1, 10, 5)?

TIA, -giobuon
