The following figure shows the storage system resources that you can configure and manage using VSP One Block Administrator.
Drives
Drives are hardware composed of storage media, and devices for reading and writing to the storage media. Drive capacity is shown as physical capacity in one of the following units: KB (kilobyte), MB (megabyte), GB (gigabyte), or TB (terabyte).
Drive groups
Drive groups (also called parity groups or RAID groups) are collections of physical drives that make up RAID in the storage system.
Pools
Pools are virtual areas in the storage system that are associated with drive groups. Thin provisioning provides virtual volumes to a server and uses the actual capacity from a pool when a server makes a write request.
Volumes
Volumes are virtual storage areas attached to the server.
Snapshots
Snapshots are images of volumes at a specific point. When you create a snapshot, differential data from the original volume is stored in the pool. You can also use snapshots to create backups.
Ports
Ports are interfaces for connecting storage systems with servers.
Servers
Servers are units for managing business servers that use a storage system managed by VSP One Block Administrator. For cluster configurations, VSP One Block Administrator manages all of the servers (nodes) that make up a cluster as one server.
