Ultra Wide SCSI - 30

 

There are three SCSI buses on the WS 9650: SCSI-3 Ultra 

Wide (68-pin); SCSI-2 Fast (50-pin); and SCSI-1 Slow 

(50-pin). This section describes these three SCSI buses and  

how units are configured at the factory.

All internal hard drives in the WS 9650 are connected to the 

68-pin Ultra Wide SCSI cable, which attaches to the Ultra 

Wide JackHammer•SE PCI card. This is known as the SCSI-3 

Ultra Wide bus. A maximum of four devices can be attached 

on this SCSI bus, and the maximum data transfer rate is 40 

MB/s.

The CD-ROM drive and optional tape drive are connected to 

the 50-pin, SCSI-2 Fast bus. A total of seven drives can be 

attached to this bus, which transfers data at a maximum rate 

of 10 MB/s.
