I have an EISA server built by Unisys, and I have some
very nice SCSI
cards for it built by Adaptec and Buslogic. The only Adaptec card for
Microchannel is based in the 1540 series (ISA) and is only good for
5megs/sec, just like the ISA version. My EISA SCSI cards are good for
10 or 20megs/sec depending on the card. I wish Adaptec would have made
a 32-bit Microchannel card based on the 7800 series Adaptec chip, like
the EISA cards. Microchannel SCSI cards from Buslogic must be very
rare.... I haven't seen a single one on Ebay since I have been looking.
I haven't really looked into the IBM Fast/Wide because I really want a
differential card, and the Diff version seems to be RS6000 only.
I suggest you have a look at Louis Ohland's pages at
http://webpages.charter.net/ohlandl/. He's got info on just about every MCA
card available, and just about every variation, too.
Besides it uses funky connectors and the cables seem to
be quite rare.
Well, that's true, but at least it's got a narrow header (all right, I don't
think that there's any official card-edge SCSI connector, but IBM uses it, of
course).
