Agreed, LSI based HBAs are all pretty reliable. These chips can be
found on motherboards, LSI branded HBAs, as well as IBM, Intel, and
other branded HBAs. The multi-lane Adaptecs are good as well.
Honestly, I've only really heard of serious problems with the mvsas
driver and the Marvell SAS 88SE64xx based HBAs, most often the
Supermicro, but also the Highpoint 2600 family. There may be others.
