Chapter 8. Storage pools 359
8.3 Working with storage pools
Storage pools act as a container for MDisks and provision the capacity to volumes. They are
comparable to MDisk Groups in IBM SAN Volume Controller or an array or a group of disks
managed by a storage controller. IBM Flex System V7000 Storage Node organizes storage in
storage pools to ease storage management and make it more efficient. Storage pools and
MDisks are managed in MDisks by Pools window. You can access the MDisks by Pools
window by clicking Home Overview and clicking the Pools icon. Extended help
information for storage pools is displayed, and if you click Visit Pools, the MDisks by Pools
window opens. It was shown previously in Figure 8-23 on page 335.
The other way to access the Pools window is to click the icon to the left that shows a physical
hard disk, the Pools icon.
The
MDisk by Pools window (Figure 8-60) allows you to manage storage pools, both internal
and as external. All existing storage pools are displayed row-by-row. The first row contains the
item
Not in a Pool, containing all unmanaged MDisks, if any exist.

Tip: When using IBM Real-time Compression volumes, it is recommended to use separate
storage pools for compressed and non-compressed volumes. To achieve the best results,
compressed and non-compressed volumes should NOT be part of the same MDiskgrp
(storage pool). For more details on the best practices to follow, see Real-time Compression
in SAN Volume Controller and Storwize V7000, REDP-4859.
