Hi.
I have a MTI Stingray SCSI HSC. I.e. a 3 U 19" rack mount box that has a
VAX CI (4 x Coax) interface on one side and a (HVD) SCSI interface on
the other side. It appears on the CI as single cluster node with several
attached disks, like a real DEC HSC.
Together with the HSC come four SCSI drive canisters. Each of it can hold
at least two SCSI disks. The SCSI drive canisters also contain some
electronic to convert the 8 bit single ended SCSI bus of the disks to the
8 bit HVD SCSI bus of the Stingray HSC.
There is also rack mount stuff for the drive canisters. So you can get a
complete CI HSC with 7 SCSI disks in 9 U 19" rack space.
I have a MTI CIQBA Qbus to CI adapter also. Yes, a Qbus to CI adapter.
It needs special (VMS) drivers that you can get from MTI.
There are no disks in the canisters. I had to leave the disks at the
company where I got this machinery. There where some Seagate and
Micropolis disks in the range from 2 to 4 GB in the canisters.
I suspect that 7 x 4 GB is sufficient for a small home VAX cluster. ;-)
Unfortunately I don't have any cables, so I can't test this. All I did
was to plug in a MMJ cable to the console of the Stingray SCSI HSC and
play with its firmware.
I would like to trade SCSI HSC + drive canisters + CIQBA for some other
nifty equipment, preferably DEC, but I am interrested in any *ix stuff.
(Even if it is younger then 10 years. Special Interrest: SGI Octane CPU
mudule > 300 MHz R12k or Vpro GFX or HP9000 Cxxxx. ;-) )
