Menu path

Fields

RAID type

The supported or available RAID types (for example, RAID 5 and RAID 10). This field is required.

Create an 8 disk array

The checkbox that you select to make the array an 8-disk array.

Array sites for arrays

The available array sites for creating arrays. You must select at least one array site from the table, and no more than half of the available array sites. This allows you to have enough space to configure a second array site. The table columns are defined as follows:

Select

Allows you to select an array site.

Array Site Number

The identifying number for the array site (for example, S1123).

DA Pair

The device adapter (DA) pair number which identifies the DA pair that is associated with the array (for example, 11).

DDM capacity

The specified capacity in gigabytes (for example, 146 or 300).

RPM

The revolutions per minute (for example, 15 000).

Class

The disk class, either enterprise or near-line. Enterprise is a high end disk drive and has the highest reliability and near-line is a lower end disk drive that has lower reliability than enterprise disk drives. Near-line storage is a compromise between online storage (constant, very rapid access to data) and offline storage (infrequent access for backup purposes or long-term storage). Near-line storage is for applications that require quicker random access, but do not require the continuous, instantaneous access that is provided by online storage.
