If I enable multipath, do I get twice the throughput between my linux box and the array ? Or is multipath purely for failover. Additionally do I get twice the bandwidth anyhow since both HBA's see the same disk ? How can I tell if either one or the other or both hba's are being utilized... These are private loops being run in full duplex.
