Volumes overview

A volume is an identifiable unit of data storage that exists on a storage medium, such as a disk or a hard drive. The C: drive, for example, is a volume space that contains the operating system functionality. You can create other logical drives (partitions) using the remaining space on the storage medium, but do not modify the C: volume itself.

Each logical drive (partition) has its own function and parameters, and operates independently. You can create a volume in a partitioned space, and then format the volume using the NT File System (NTFS) or the Resilient File System (ReFS) to store directories and files. For a detailed description of NTFS and ReFS see, the Microsoft NTFS overview and ReFS overview. Do not create more than 23 volumes.

The maximum volume size is 64 TiB. You can only increase the size of the volume. You can create less volume in size, and then increase the size of the volume as required.

The HPE StoreEasy management console supports both snapshots and deduplication of volumes. You can create a snapshot (a copy) of a volume at a particular point and time using either the scheduling feature, or the automatic snapshot feature. For more information on snapshots, see Snapshots.

Deduplication works for the entire volume, locating and caching duplicate copies of information to reduce the use of storage space and increase performance on large, heavily used volumes. For more information on deduplication, see Deduplication on a volume.
