I'm in the middle of testing this controller on an ES40 (4 CPU Alpha).
I should get some numbers next week.  So far with a 4+p RAID 5 I'm
seeing about 17MB/s write performance with a single chain.  I think
these are only 7200 RPM drive.  I don't really care about read
performance but that was up around 30MB/s.  Next week I should be
testing with 2 cards per server with 3 chains on one and 2 chains on
another.  I'm trying to reach 100MB/s write performance on a single
server.  I really doubt I'll get that with this card, I'm nearly
certain I'll have to go with an external Fibre Channel solution with a
smart enclosure.
