The following table provides definitions for some of the terms that are used in this document.
Term | Definition |
Appliance | Solution containing the base enclosure and any attached expansion enclosures. |
Base enclosure | Enclosure containing both nodes (node A and node B) with 25 x NVMe drive slots in the front. |
Cluster | One or more appliances in a single grouping and management interface. Clusters are expandable by adding more appliances to the existing cluster, up to the allowed amount for a cluster. |
Expansion enclosure | Enclosures that can be attached to a base enclosure to provide additional storage. |
NVMe over Fibre Channel (NVMe/FC) | Protocol used to perform Non-Volatile Memory Express (NVMe) commands over a Fibre Channel network. |
NVMe over TCP (NVMe/TCP) | Protocol used to perform Non-Volatile Memory Express (NVMe) commands over an Ethernet network. |
Fibre Channel protocol | Protocol used to perform Internet Protocol (IP) and SCSI commands over a Fibre Channel network. |
File system | Storage resource that can be accessed through file-sharing protocols such as SMB or NFS. |
Internet SCSI (iSCSI) | Provides a mechanism for accessing block-level data storage over network connections. |
Network attached storage (NAS) server | File-level storage server used to host file systems. A NAS server is required to create file systems that use SMB or NFS shares. |
Network File System (NFS) | Access protocol that allows data access from Linux or UNIX hosts on a network. |
Node | Component within an appliance that contains processors and memory. Each appliance consists of two nodes. |
PowerStore Q | 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 | 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 | Set of resources (objects), operations, and attributes that provide interactive, scripted, and programmatic management control of the PowerStore cluster. |
Server Message Block (SMB) | Network file-sharing protocol, sometimes referred to as CIFS, used by Microsoft Windows environments. SMB provides access to files and folders from Windows hosts on a network. |
Snapshot | 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. |
VMware vSphere Virtual Volumes (vVols) | A VMware storage framework which allows VM data to be stored on individual Virtual Volumes. This ability allows for data services to be applied at a VM-level of granularity and according to SPBM. Virtual Volumes can also refer to the individual storage objects that are used to enable this functionality. |
