Ultra160 SCSI ports
Your server has an integrated dual-channel Ultra160 small computer system
interface (SCSI) controller. This controller supports two independent Ultra 160/m
SCSI channels, both internal. Each of these channels supports up to 15 SCSI
devices. In addition, this controller uses:
v
Double-transition clocking to achieve high transfer rates
v
Domain-name validation to negotiate compatible data transfer speeds with each
device
v
Cyclic redundancy checking (CRC), instead of the usual parity checking, to
significantly improve data reliability
v
An active terminator on the system board for SCSI bus termination
A SCSI cable connects the SCSI channel A connector to the hot-swap drive
backplane. If you obtain an additional SCSI cable, the SCSI channel B connector is
available for connecting non-hot-swap SCSI drives in the 5.25-inch bays.
If you install a SCSI adapter in your server, you can use its SCSI connector to
connect different types of small computer system interface (SCSI) devices.
Note:
If you install a PCI RAID adapter to configure and manage the internal
hot-swap drives, you must move the SCSI cable from the system board SCSI
channel A connector to an internal channel connector on the RAID adapter.
SCSI cabling requirements:
If you plan to attach external SCSI devices, you must
order additional SCSI cables. To select and order the correct cables for use with
external devices, contact your IBM reseller or IBM marketing representative.
