Small Computer System Interface (SCSI) Controllers The HP Kayak XU PC Workstation has two SCSI controllers: an Ultra-wide (16-bit) SCSI and a narrow (8-bit) SCSI. AIC-7880 Ultra-wide (16-bit) SCSI controller The Adaptec AIC-7880 Ultra-wide SCSI PCI controller is integrated on the HP Kayak XU PC Workstation system board. Data is transferred at 40 MB/s on 16-bit wide, single-ended bus. The controller is fitted with a 16-bit SCSI flat cable with five connectors, plus a SCSI termination device; so a maximum 20
