The Background Tasks pane displays all long-running tasks that are 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 3-33 shows an example of a FlashCopy Operation.

## 3.3 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 an 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 lists the extent sizes.
