The following figure shows the storage system resources that can be configured and managed 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 displayed as physical capacity in one of the following units: KB (kilobyte), MB (megabyte), GB (gigabyte), or TB (terabyte).
Pools
Pools for thin provisioning are virtual areas in a storage system that are associated with multiple drives. 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 a snapshot is created, differential data from the original volume is stored in the pool. Snapshots can also be used 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 by VSP One Block Administrator. For cluster configurations, all of the servers (nodes) that make up a cluster are managed as one server.
