We are torn between a LeftHand SAN and and a Compellent SAN and wondering if anyone had any thoughts either way. The lefthand solution was all iSCSI (of course) and consisted of a SATA box(x2) and a SAS box (x2) for geographic redundancy. The Compellent SAN consisted a one enclosure outfitted with both SAS and SATA drives (x2)... I like the Compellent feature set but their software maintenance is HEAVY.. The lefthand san is great especially the network RAID but that all affects storage.. I guess just looking for thoughts either way.. Thanks..
