Notes Notes: 1. The Requested Space default value is calculated as the maximum logical drive size available for the RAID level assigned. 2. The Requested Space must be between 2 MB and the maximum available. 3. The actual logical drive size that appears might be slightly different from what you type in the Space Requested field. The size of a logical drive is determined by the RAID level and the number of hard disk drives. For example, a disk array consisting of three, 1 GB hard disk drives with a requested RAID level 0 logical drive of 1000 MB will actually contain only 999 MB because the data is striped across all three drives, with 333 MB on each drive. 6. Click on OK to create the disk array. 7. You must initialize all new logical drives before storing data in them. See "Initializing logical drives" on page 36. Note All new RAID level 5 logical drives are automatically synchronized when you initialize them. Deleting Disk Arrays Deleting a disk array deletes all logical drives that are defined in that array. All data and programs in the disk array are lost during this procedure. Note For some operating systems, deleting a disk array and its associated logical drives will change the drive letters that are assigned to the remaining drives when you restart the system. Attention Before proceeding, ensure that you have backed up any data and programs that you want to save. To delete a disk array: Netfinity 5500 - Type 8660 33
