Check recent issues of Linux Journal.  I recall seeing a vendor with boards
up to 8 channels of UDMA, though it was a raid solution.  They were also at
Linux World earlier this year.

And dang it, I can't remember the name :(

Subject: UDMA Cards and HD CRC Checks


I need to select a multi-port (8) UDMA UltraATA board for a set of disks
attached to each node of a Beowulf, and then write something to get the CRC
periodically to check integrity (we will not be using RAID for various
amoung other checks.  I have been looking at 'hdparm'.

Can anyone suggest a good board for this, and tell me where to look re
CRC info out of a disk (aka md raid like commands)

TIA, I will summarise
