Throughput correction

I got my math VERY wrong for the new LSI HBA card, because I thought it was based on an onboard port expander. It is not. The card has two, four-lane 6G SAS connectors, for a total throughput of 48Gbit/sec. Divide that total throughput by the 24 attached drives, and you get a maximum theoretical throughput of 2Gbit/sec (200Mbyte/sec) per attached drive.
