3.3.5 Background Task
Use the Background Tasks page to view and manage current tasks that are running on the
system. The Background Tasks page displays all long-running tasks that are currently in
progress on the system. Tasks, such as volume synchronization, array initialization, and
volume formatting, can take some time to complete. The Background Tasks page displays
these tasks and their progress. After the task completes, the task is automatically deleted
from the display. If a task fails with an error, select Monitoring → Events to determine the
problem. Figure 3-32 shows an example of a Flash Copy Operation.

3.4 Pools menu
A pool or storage pool is a collection of MDisks that jointly contain all of the data for a
specified set of volumes. All MDisks in a pool are split into
extents of the same size. The size
of the extent defines the maximum usable capacity of a IBM Storwize Virtual System. An IBM
Storwize Virtual System can address 2^22 extents. This enables you to address a maximum
of 32 PB with 8192 MB extents. Table 3-1 shows the extent sizes.
