Terminology

Also known as a storage pool. An array is a group of physical drives in one or more drive enclosures combined with controller software, that represents disk storage capacity as one or more logical drives.

A read-only copy of data copied to media, such as hard drives or magnetic tape, for data protection. A full backup involves copying of all the data to the media. An incremental backup copies only the data that has changed since the last full backup. Backups provide data protection if the system fails as the data is copied and stored on a separate media.

Customer Self Repair (CSR) indicates that the system can be repaired by the customer. No OEM-trained technician intervention is required.

Distributed File System Namespace (DFS-N) is a service that allows grouping of shared folders on several distributed file servers into one or more namespaces. Each namespace appears to an end user as a shared folder with a series of subdirectories.

DFS-N also allows the definition of primary and secondary datapaths that allow redirection of users to redundant file servers. If the primary path fails, users are automatically redirected to one of the standby file servers. This is used in combination with DFS-R.

Distributed File System Replication (DFS-R) is an application that enables organizations to use synchronized folders for HPE StoreEasy Storage systems on networks that have a limited bandwidth.

It also allows administrators to asynchronously replicate folders between two file servers that are joined to the same Active Directory domain. Used for recovery purposes and in combination with DFS-N to enable a transition between primary and secondary file servers.

Initial Configuration Tasks (ICT) provides a list of actions that must be performed during the initial setup and configuration of an HPE StoreEasy Storage system.

Logical drive (LDEV) allows you to partition arrays into one or more logical segments. This is done to logically group data or to limit capacity usage for specific use cases. A logical drive is also referred to as a virtual disk.

Logical Unit Number (LUN or LUNs) results from mapping a logical unit number, port ID, and LDEV ID to a RAID group. The size of the LUN is determined by the emulation mode of the LDEV and the number of LDEVs associated with the LUN.

LUN may span all physical drives within a Storage File Controller subsystem, but cannot span multiple storage controller subsystems. The multiple storage controller subsystems could indicate multiple controllers or external enclosures.

A host file system path or directory name where a host volume (device) is accessed.
