- Sun does assert that SCSI disks are not supported on the 4/490
- or 4/690 servers. The fact is, the 4/690 *is* a 4/670 with a larger
- VME backplane, mounted in a non-standard 19" rack. Both use the same
- system board. Basic rule of thumb: If it works on a 4/670 it will
- work on a 4/690. The 490 and 690 are not sold by Sun with SCSI, so
- the decision not to support this is a marketing one.
-
- We bought our 4/490 as an upgrade from a 3/280 and so it came diskless.
- We have three VME SCSI boards, each with from two to four 1.2GB Seagate
- ST41200N (CDC Wren VII) drives. (By the way, the Wren VII is NOT SCSI-2,
- but it does synchronous transfers > 4MB/sec).
-
- We recently purchased the 690MP upgrade, along with two of the SBE
- (SCSI/Buffered Ethernet) cards you described. We have also purchased
- the SBus Prestoserve board. All will be installed this Thursday
- evening... I will be posting the results here.
