RE: [OT] SCSI drive question

[Paul Bunn <paul ultrabac com>]

This is normally true.

However, I've just got a killer new SCSI card from Tekram that has a Symbios
53C895 chip that handles the LVD/Ultra2 SCSI bus, but also has a Symbios
53C141 isolation chip that allows the card to be connected simultaneously to
an UW and LVD bus.  On the card for internal connections it has an LVD
connector, UW connector and 50pin narrow connector -- the LVD connector and
one of the other connectors can be used at the same time.  The external
connector is always LVD (connecting a UW device to this connector I would
assume would disable LVD to the internal LVD bus too).  Great card --
haven't tried it with Linux, but I assume it should work...

The drive will run at the maximum speed of either the drive / controller
(whichever one is slower)
so for example if you take an U2W drive and put it on a UW controller it
will run at 40MB/s

you can mix drive speeds on anything but U2W / LVD
if you put non LVD drives on the LVD channel the whole channel will run just
at UW (non LVD) and will slow the U2W drives down to UW
