(1) S400/S1400/S2400/S2800
S400/S1400/S2400/S2800 disk array allows the user or the system engineer to bind logical disks.
1. Specify the capacity of one logical disk in units of 1 GB*1.
2. Now you can select a recommended capacity (already used in the 3000/4000 series disk array)
from a pull-down list.
The table below shows the recommended capacities. (A logical disk’s capacity smaller than
0.1 GB*1 is shown rounded*2 on the configuration setting summary display.):
3. On S400/S1400/S2400/S2800 disk array, you can bind logical disks of the same capacity
regardless of pool type and RAID configuration. (On the 100/1000/2000 series disk array
(not including S400/S1400/S2400), capacities of logical disks you can use are different
depending on the RAID configuration.)
4. The real capacity of each logical disk includes additional 2 MB region for disk control, which
makes it available for the user. On S400/S1400/S2400/S2800, binding a pool may cause the
capacity assigned to a pool (pool used capacity) to exceed the capacity of the logical disks.
*1: iSM handles 1024 KB as 1 MB.
