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. -- Stan
