I haven't tried Promise recently, but last time I did I determined that
they got the name because they "Promise" the Linux driver for your card
will be available real-soon-now. Actually got strung along for a couple
months before calling my supplier and telling him to swap it out for a
3ware. The 3ware "just works". I currently have a couple dozen Linux
servers, including some PostgreSQL machines, running the 3ware cards.
Cheers,
Steve
