Volume properties

The following table describes the field names shown in the HPE StoreEasy management console status screen for a selected volume. You can configure some of these items when you create a volume. You can add or modify others when you edit a volume. Other properties provide information only and are not modifiable by the user under volumes.





Volume name.

Volume names can include the following special characters: `~!@#$%^&*()_-+={[}]|\:;'<,>.?/

The double quote (") is the only restricted character.

Total Size

Represents the total size of the volume, indicating the amount of space allocated for storage within that volume. Measured in Mebibytes (MiB), Gibibytes (GiB), or Tebibytes (TiB). You can choose custom values for these settings, or use the maximum available capacity for the volume.

Free Space

Free space indicates the amount of available space left on the volume after deducting the amount of space already used. The calculation is the difference between the total allocated space for the volume and the total used space on the volume. This is an informational setting that provides detail at a glance so administrators can monitor the volume usage and space requirements.

File System

NT File System (NTFS) or Resilient File System (ReFS) file system used to format the volume. NTFS, developed by Microsoft for the Windows NT operating system, stores and retrieves files. ReFS, also developed by Microsoft, provides additional capabilities to support current storage and retrieval requirements. For more information, see the Microsoft NTFS overview and ReFS overview.

Drive Letter

Drive letter of the file system on which the volume is mounted. The assigned drive letter becomes a unique property of the volume. You cannot use the same drive letter for more than one volume.

Allocation Unit

The allocation unit defines the smallest unit of space that data uses on the file system. For example, if you have an allocation unit of 8 KiB and you want to store a 1 KB file, the file consume 8 KiB on the volume. Because the system reads data from the volume in blocks, you can use this allocation unit to optimize reads and writes. For system running sequential workloads, the larger the allocation unit, the better. If you have very large volumes and a small allocation unit, you won't efficiently use the full capacity of the volume.

However, if you have a random workload and small files, a larger allocatiom unit lowers performance because the system read larger chunks of information from the disk you actually need, which is an inefficient use of capacity.

Hewlett Packard Enterprise recommends leaving this setting at the default value so that the system determines the appropriate allocation unit based on the volume size.

Logical Drive

If you review the architecture section that Deb has provided, it might become clear. Volumes are created within logical drives. A user has to select in which logical drive the volume shall be created. Layer by layer, StoreEasy adds functionality to the storage from physical drive to file share.

File Shares

This setting indicates the number of file shares provisioned on a volume, provided for information purposes only.


Deduplication Modes

Data deduplication optimizes volume space by looking for duplicated information on the volume, storing it once, and (optionally) compressing it. This process frees up space on a volume and saves money by reducing the need to purchase additional storage. You can enable deduplication for different purposes. HPE StoreEasy supports deduplication for general use across the file server, or you can enable deduplication on a virtual server used by remote desktop users or for a virtual backup server (see, Microsoft Data Deduplication Overview).

The HPE StoreEasy management console supports deduplication for NTFS only. If your volume uses ReFS, the management console does not provide deduplication options.

Minimum File Age

Determine the number of days that should pass before a file becomes eligible for deduplication. Deduplication of files that users no longer access regularly provides a more efficient use of deduplication resources.

Excluded File Types

By default, HPE StoreEasy excludes certain file types from deduplication. You can specify additional file types to exclude, but you cannot change the default file types. The excluded file types depend on the mode of deduplication you choose.

HPE StoreEasy management console excludes certain file types to prevent performance issues by deduplicating files where dedupliation has not real benefit (for example, where the deduplication effort would not save space). You can add your own files to this list when you know those files won't deduplicate well. This might include encrypted files, can cause deduplication issues.

Saved Space

Shows the difference between the actual size of the files on the volume and the size of the logical drive after deduplication. Savings you see using deduplication depend on the data stored and the workload usage on the volume.

Unoptimized Size

Indicates the total size on the disk without deduplication.


Indicates the total volume size and a bar graph that shows how much of total space is used.

Snapshot Schedules

Displays the list of scheduled snapshots, if any. Displays additional information, such as date and time of the snapshot, depending on the schedule type (see, Adding a snapshot schedule using HPE StoreEasy management console)


Lists the existing snapshots for the selected volume.
