What is a storage pool?
A storage pool is capacity aggregated from disparate physical storage resources in a shared storage environment.
Admins can provision pools to include any amount of capacity and use any combination of physical storage space in a storage area network. In virtual server environments, admins can use dedicated pools to store virtual machines to ensure critical VMs can access the proper amount of storage.
Vendors often provide the capability for admins to provision storage pools through a management interface. For example, the Storage Spaces feature in Microsoft Windows Server provides pooling capabilities. Tools such as IBM Tivoli Storage Manager and Google Cloud Backup and Disaster Recovery Service also enable this type of provisioning.
