Order Number	System Disk
DS-RZ1CF-VW	4.3 GB 7200 RPM UltraSCSI disk
DS-RZ1DF-VW	9.1 GB 7200 RPM UltraSCSI disk
DS-RZ1EF-VW1	18.2 GB 7200 RPM UltraSCSI disk

1. 18.2GB disk drives are not supported on KZPAC-xx PCI-based RAID controllers

Select two SCSI ports Mandatory

Two SCSI ports are mandatory to support internal storage:

-Internal removable media devices are supported on KZPCM-DA and KZPBA-CA adapters only. Internal removable media devices are not support on KZPAC-AA/CA/CB RAID controllers.

-Internal StorageWorks seven disk shelf requires one SCSI port when configured in single-bus mode1 System includes SCSI cable(s) to connect SCSI adapters/controllers to internal storage.

1.To configure StorageWorks disk shelf in split-bus mode one addition SCSI port is required.

The requirement of two SCSI ports can be fulfilled by ordering:

One KZPCM-DA two port UltraSCSI single-ended adapter, or

￿Two KZPBA-CA one port UltraSCSI single-ended adapter, or

One KZPBA-CA one port UltraSCSI single-ended adapter and one KZPAC-AA/CA/CB UltraSCSI RAID controller.

Order Number	SCSI Adapter
KZPCM-DA	PCI-based two port UltraSCSI Single-ended adapter and 10/100 Mbit Ethernet Combo adapter
KZPBA-CA	PCI-based one port UltraSCSI Single-ended adapter
KZPAC-AA	PCI-based one port UltraSCSI RAID controller
KZPAC-CA/CB	PCI-based three port UltraSCSI RAID controller

Select one Ethernet Adapter Mandatory

Note: Ethernet adapter is not required if KZPCM is selected as the SCSI adapter.

Order Number	Network Adapter
DE500-BA	PCI-based 10/100 Mbit Fast Ethernet adapter UTP
DE504-BA	PCI-based 10/100 Mbit Quad Channel Ethernet adapter
