The following table provides definitions for some of the terms that are used in this document.
Table 1. Terminology
Term | Definition |
Appliance | Term used for solution containing a base enclosure and any attached expansion shelves. The size of an appliance could be only the base enclosure or the base enclosure plus expansion enclosures. |
Cluster | Multiple appliances in a single grouping. Clusters can consist of one appliance or more. |
File system | A storage resource that can be accessed through file sharing protocols such as SMB or NFS. |
NAS server | A virtualized Network-Attached Storage server that uses the SMB, NFS, or FTP/SFTP protocols to catalog, organize, and transfer files within file system shares and exports. A NAS Server, the basis for multi-tenancy, must be created before you can create file-level storage resources. NAS servers are responsible for the configuration parameters on the set of file systems that it serves. |
Network File System (NFS) | An access protocol that enables users to access files and folders on a network. NFS is typically used by Linux/UNIX hosts. |
PowerStore Command Line Interface (PSTCLI) | An interface that allows a user to perform tasks on the storage system by typing commands instead of using the UI. |
PowerStore Manager | The web-based user interface (UI) for storage management. |
PowerStore Q model | Container-based storage system that is running on purpose-built hardware. This storage system supports unified (block and file) workloads, or block-optimized workloads. The PowerStore Q model supports Quad-Level Cell (QLC) NVMe SSDs for data storage. |
PowerStore T model | Container-based storage system that is running on purpose-built hardware. This storage system supports unified (block and file) workloads, or block-optimized workloads. The PowerStore T model supports Triple-Level Cell (TLC) NVMe SSDs for data storage. |
Representational State Transfer (REST) API | A set of resources (objects), operations, and attributes that provide interactive, scripted, and programmatic management control of the PowerStore cluster. |
Server Message Block (SMB) | An access protocol that allows remote file data access from clients to hosts on a network. This is typically used in Microsoft Windows environments. |
Snapshot | A point-in-time view of data stored on a storage resource. A user can recover files from a snapshot or restore a storage resource from a snapshot. |
Storage resource | The top-level object a user can provision, associated with a specific quantity of storage. An example of a storage resource is a volume, volume group, or file system. All host access and data protection activities are performed at this level. |
Thin clone | A read/write copy of a volume, volume group, file system, NAS server, or snapshot that shares blocks with the parent resource. |
Volume | A block-level storage device that can be shared using a protocol such as iSCSI or Fibre Channel. |
Volume group | A storage instance which contains one or more volumes within a storage system. |
