In a disk array, put multiple physical disks together to set up a virtual medium to compose RAID, and
partition the space in the virtual medium to make logical disks. Data on the logical disks is stored into
the areas of physical disk associated with the partitions on the virtual medium in which the logical disks
are composed.
The virtual medium is called a pool or RANK, and it supports different logical disk configurations
depending on the disk array.
• Pool
<Supported disk array>
S400/S1400/S2400/S2800
In the disk array indicated above, multiple physical disks put together to make up a virtual medium
for RAID is called a pool. The logical disks usually belong to one pool, and the required amount of
space is assigned from the pool.
• RANK
<Supported disk arrays>
Other than S400/S1400/S2400/S2800
In the disk arrays indicated above, multiple physical disks put together to make up a virtual medium
for RAID is called RANK. Areas on RANK are controlled by using a continuous address space.
There are two types of pool available as described below. They function in different manners.
