Fibre Channel: A transport protocol that provides a mechanism for accessing block-level storage resources.
File System: A file-level storage resource that can be accessed over SMB and/or NFS protocols. A NAS Server must exist on the system prior to creating an SMB, NFS, or Multiprotocol File System.
Internet SCSI (iSCSI): An IP-based transport protocol that provides a mechanism for accessing raw block-level storage resources over network connections.
LUN: A logical unit of storage provisioned from a pool. A LUN can either be a Thin LUN or a Thick LUN.
NAS Server: A file storage server that can be enabled to support SMB and/or NFS protocols to catalog, organize, and transfer files within designated shares. A NAS Server is required to create file-level storage resources such as SMB, NFS File Systems, and VMware NFS Datastores.
Network File System (NFS): An access protocol that enables users to access files and folders over a computer network. Most usage of NFS involves computers running Linux or UNIX operating systems.
Pool: A collection of drives configured with particular storage attributes. The storage attributes are defined by the type of drives used to provide storage and the type of RAID configured on the drives. Dell Unity supports unified pools that include both block and file storage resources.
Server Message Block (SMB): An access protocol that enables users to access files and folders over a computer network. Most usage of SMB involves computers running Microsoft Windows.
Snapshot: A read-only or writable point-in-time state of a storage resource’s data. Users can recover files from snapshots or restore a storage resource from a snapshot and revert it to the particular point-in-time state.
Storage Processor (SP): A hardware component that provides computing resources for storage operations including the creation, management, and monitoring of storage resources.
Unisphere: The graphical management interface for creating, managing, and monitoring Dell Unity systems storage resources and related features.
Unisphere CLI (UEMCLI): The command-line interface for managing storage systems.
