Adaptec SCSI RAID 2120S/2200S Software User’s Guide

■Revision—The version number information stored on the device.

■Data Rate—The data transfer speed negotiated between the controller and this device.

■SCSI ID, LUN—For devices on a SCSI channel the SCSI ID and LUN of the device are reported. These do not apply for ATA and Serial ATA devices and will always return 0.

Capacity Tab

The Capacity tab appears only for disk drives and when selected, displays a summary view listing the reserved, used, available, and total capacities of the drive.

The capacities are reported in both the number of 512-byte blocks (shown in both decimal and hexadecimal values) and capacity in kilobytes, megabytes, or gigabytes.

Selecting the detailed option shows information for all segments on the drive. In this view, the following information is displayed for each segment:

■Number of the segment

■Start and end blocks

■Segment size and type

Type indicates how the segment is used. The first and last segments are always reserved. The beginning of the drive is where the controller stores the RAID signature. The end of the drive is where the capacity is rounded down to the nearest 100 MB.

If this segment is a component of an array, type indicates the array level the segment is used in. If the segment is not used in an array, and is not a reserved area, it will be shown as available.

Detailed view defaults to displaying the numbers of the start and end blocks of each segment in decimal values. A drop-down list is provided to allow you to display these numbers in either hexadecimal or capacity.
