IBM Storwize V5000 Gen2 organizes storage into pools to ease storage management and
make it more efficient. All MDisks in a pool are split into extents of the same size and volumes
are created from these available extents. The extent size is a property of the storage pool and
when an MDisk is added to a pool the size of the extents that composes it will be based on
the attribute of the pool to which the MDisk was added.
Storage pools can be further divided into sub-containers named as
child pools. Child pools
inherit the properties of the parent pool and can also be used to provision volumes.
Storage pools are managed either through the Pools panel or the MDisks by Pool panel. Both
panels allow you to run the same actions; however, actions on child pools can be performed
only through the Pools panel. To access the Pools panel browse to Pools → Pools, as shown
in Figure 4-19.
