2.14. PCI SCSI-3 Ultra/Wide RAID SE Adapter - DPT (CKTG068 and CKTG075)

The PCI SCSI-3 Ultra/Wide SE Adapter is a Dual ported Ultra (20 MHz) and wide (16-bit wide) SCSI
PCI Adapter that can provide synchronous SCSI bus data rates of up to 40 megabytes per second on
each port. The PCI SCSI-3 Ultra/Wide SE Adapter provides high performance attachment to internal
Single Ended SCSI disks. The maximum data rate depends on the data rate of the attached devices.
The PCI SCSI-3 Ultra/Wide SE Adapter has two internal Single Ended ports. One of these ports is also
available on the external connector. Each port is capable of addressing up to 15 Single Ended devices.
The number of physical devices attached is limited by SCSI bus cabling restrictions. The external port
of this adapter supports 8-bit or 16-bit devices via a 16-bit connector.
The PCI SCSI-3 Ultra/Wide SE Adapter supports RAID functionality (RAID 0, RAID 1 and RAID 5
mode) and is designed with 16 MB cache upgradable to 64 MB.
It provides SAF-TE and "Storage Works" capabilities (fault detection and management).
This adapter is used with the internal disks.
