Hardware Specifications and Features
Note:
Compatibility refers only to how data and RAID configuration information are written to
the hard disks. Compatible controllers have the same data file format.

Configurable Disk Drive SCSI Parameters
When a SCSI hard disk drive is initialized the first time by the RAID controller, its SCSI
parameters are automatically set to their optimal settings. Most settings are set
automatically and can not be configured manually. To view or configure disk drive SCSI
parameters from the Storage Console, choose Advanced Setup

Description
Synch.

Automatic
This setting when enabled allows the controller to
operate in synchronous transfer mode
Synch.
Transfer Rate
Speed
(MB/sec)
Automatic
Allows for the setting of the speed for the SCSI
hard disks (up to 320 MB/sec for U320 drives).
No matter the setting, the SCSI bus will negotiate
the fastest speed up to this setting. Lowering the
setting will force the disk drive to transfer at the
lower speed.
