This section explains disk array specifications and software specifications, according to which the
capacities of logical disks of this disk array series are to be determined. The section mainly explains
the capacities of logical disks which are to be bound in a non-recommended RAID configuration. Use
“Individual Setting” of Configuration Setting (GUI) to bind logical disks in a non-recommended RAID
configuration.
(1) Disk array specifications
This disk array series requires that the capacity of a logical disk of the RAID type (RAID0,
RAID10, or RAID5) using the striping feature is a multiple of “striping size × number of data
disks*”.
The striping size for of this disk array series is defined as 128KB. Thus, “128KB × number of
data disks” is the capacity unit of logical disks to be bound, as shown in Figure D-1.
Figure D-1 Capacity Unit in Binding
*: A data disk is a physical disk, which is used to save data in RAID configuration. The
number of data disks is 1 in configuration of RAID1(1+1); it is 4 in configuration of
RAID5(4+P). In other words, if a RAID configuration is expressed as RAID5(n+P) or
RAID10(n+n), “n” is equal to the number of data disks.
