Installation

Fast Wide SCSI Mode

Several possible configurations exist for the CR8e in the Fast Wide SCSI mode: dual-bus with one or two enclosures, single-bus with one or two enclosures, and one dual-bus enclosure with two single-bus enclosures connected.

When configuring a dual-bus enclosure subsystem with an AM RAID Controller, one channel on the controller connects to Channel #0 on the I/O Interface card and the other channel on the controller connects to Channel #1 on the I/O Interface card – each channel addresses either the upper (right) or lower (left) bank of drives. When configuring the single-bus enclosure with an AM RAID Controller, one channel on the controller connects to the right or upper channel (Channel #1) connector on the I/O Interface card and addresses both banks of drives.

From the front, the drives slots are divided into two banks. The left or upper four front drive slots, which are connected to “Channel 1” on the I/O Interface card, and the right or lower four front drive slots are connected to “Channel 0” on the I/O Interface card.

Single Dual-Bus Enclosure

With the Single-Bus module is installed, all of the disk drives in the CR8e enclosure are on the same SCSI bus. With this configuration you will have a total storage capacity of up to 145 GB (using 18 GB disk drives) per subsystem enclosure and have access to the drives independently or as a single large array.

The SCSI IDs of the drives are set by the SAF-TE card defaults to IDs 0, 1, 2, and 4, from the front beginning with the drive located on the right or lower slot of each bank. The SCSI IDs can be manually changed from the OCP, if required. Both banks of drives will normally use the same sequence of SCSI ID numbers when the Dual-Bus module is installed.

NOTE: SCSI ID 3 is reserved for the SAF-TE card processor.

CAUTION: Ensure that the power switch is in the OFF (O) position for both the host system and the CR8e subsystem before connecting any cables.

1Connect one end of a one meter data cable to the Channel #1 connector on the AM RAID Controller.
