Chapter 8 Disk Array Configuration Setting
(S100/S1100/S1200/S1300/S2100/S2200/
S2300)
This chapter describes how to set the configuration of the disk array in S100/S1100/S1200/S1300/S2100/S2200/S2300. For
configuration setting in S400/S1400/S2400/S2800, refer to Chapter 7.

The RANK is bound by specifying the physical disks and the RAID type for binding RAID from the physical disks
installed on the disk array. Then, for the RANK thus bound, logical disks can be bound by binding logical disks.
When extending physical disks, logical disks can be bound for the extended physical disks in accordance with the same
procedure, thus not affecting the logical disks on other RANKs already in use. Even when new logical disks are
additionally bound for the same RANK, they do not affect the already bound logical disks.
Regarding LD binding, selections can be made from the following configurations, thus making possible a different
configuration for each RANK.
Logical disk configuration: RAID1 (1+1)
RAID5 (2+P)/(3+P)/(4+P)/(5+P)/(6+P)/
(7+P)/(8+P)/(9+P)/(10+P)/(11+P)/
(12+P)/(13+P)/(14+P)
RAID0 1/3/5/10/15
RAID10 (2+2)/(3+3)/(4+4)/(5+5)/(6+6)/(7+7)
* Only Windows and Solaris can specify RAID0. However, do not use RAID0 in a highly reliable system (e.g.,
cluster environment) because RAID0 has no redundancy.
Logical disks are bound for the 3000/4000 series disk array when it is initially installed.
