Boot from iSCSI w/MPIO & iSCSI Initators in Windows.
Sparks more of my interest in Nimble Storage.
The extreme complexity of iSCSI boot compared to “simplistic” SAN boot, still gets an F- from RealWorldUCS. Would do iSCSI over physical drives or the SD’s that come in M3 blades now.
M3 Blades come with an optional SD Card
A blade with a personality offers short term gain followed by exactly the opposite.
