The virtual storage pool serves as a container in which required resources (physical disks) for creating a virtual disk are collected. Creating a virtual storage pool enables a clear separation between physical disks for the virtual world and those for conventional operation in the real world.
The virtual storage pool is one of the most important components of virtual storage operation.
Virtual Storage Conductor (VSC) determines the appropriate range of control regarding the virtual storage pool for each virtualization switch. Therefore, when creating a virtual storage pool, it is necessary to clearly define the relationship between the virtual storage pool and its controlling virtualization switch.
The virtualization switch for controlling a virtual storage pool must have a redundant configuration.

A virtual disk is created from physical disks that are registered in the virtual storage pool. Thus, we recommend that you create a virtual storage pool that is appropriate for each arbitrary purpose. Examples of such purpose types are as follows:
For each storage
For each RAID group
For each transaction group
You can delete any virtual storage pool that will no longer be used. However, you cannot delete a virtual storage pool that has a physical disk in it. You must release all registered physical disks from the virtual storage pool before deleting the virtual storage pool itself.
