ATTO Technology S-Class manual Examples, Unique serial number for each LUN

Page 27

Examples

JBOD mode uses 24 LUNs. Each LUN is equivalent to one physical drive. The array will operate with several sleds missing, but the empty sled(s) will be treated as offline and will not be configurable.

RAID Level 0 (QuickRAID0 [n]) With a fully populated array, RAID 0 may be configured as 1, 2, 3, 4, 6, or 12 LUNs. As QuickRAID0 1, all 24 physical drives are configured as a single stripe group or LUN. You may also configure two LUNs of 12 drives each, three LUNs of eight drives each, four LUNs of six drives each, six LUNs of four drives each and 12 LUNS of two drives each. (See Exhibit 6.2-3in RAID Level 0 on page 53). The command assumes there are 24 drives available to configure the specified number of LUNS.

RAID Level 1 (QuickRAID1) has no options: the array will be configured into six groups, LUNs 1- 6, with each LUN containing two physical sleds; each sled in the LUN will be a mirror image of the other sled in the LUN.

RAID Level 10 (QuickRAID10) The QuickRAID10

command first creates six mirrored groups, then stripes them into groups of one, two or three RAID 10 groups. Each group is a LUN. Issuing QuickRAID10 2, the 12 physical sleds are

configured as six mirrored pairs, then striped into two LUNs.

RAID Level 5 (QuickRAID5) with a fully

populated Array may be configured as 1, 2, 3 or 4 LUNs. As QuickRAID5 1, all 24 physical drives are configured as a single RAID 5 LUN. You may also configure two LUNs of 12 drives each, three LUNs of eight drives each, or four LUNs of six drives each. RAID Level 5 parity will reduce the usable capacity of each LUN by the equivalent of one drive sled.

Unique serial number for each LUN

Each LUN in a system has a unique 24-character serial number which is updated when a system configuration changes. It is stored in a Device Association Table on each drive.

When a drive or sled is replaced in QuickRAID configurations that allow for hot swap, a new serial number will be computed and will in turn be stamped onto all member drives of the RAID group. The CLI command LUNInfo or the ExpressNAV interface page Logical Units will display the serial number for each drive.

Format of the 24 characters is defined in the chart below:
