Advanced Deduplication | A dynamic deduplication algorithm which reduces storage consumption by eliminating duplicate 8KB blocks of data within a storage resource. |
All Flash Pool | A Pool which contains only Flash Drives. An All Flash Pool can be a Traditional Pool or a Dynamic Pool. |
Asynchronous Replication | A replication method which allows you to replicate data over long distances and maintain a replica at a destination site. Updates to the destination image can be issued manually, or automatically based on a customizable Recovery Point Objective (RPO). |
Block Storage Resources | LUNs, LUNs within a Consistency Group, and VMware VMFS Datastores. |
Compression | A data reduction method which reduces the physical amount of storage required to save a dataset. |
Consistency Group | A storage instance which contains one or more LUNs within a storage system. Consistency Groups help organize the storage allocated for a particular host or hosts. Data protection configurations, such as replication and snapshot settings, on a Consistency Group affect all the LUNs contained in the group, providing ease of management and crash consistency if the LUNs are dependent on each other. |
Data at Rest Encryption (D@RE) | The process of encrypting data and protecting it against unauthorized access unless valid keys are provided. This prevents data from being accessed and provides a mechanism to quickly crypto-erase data. |
Deduplication | A data reduction method which reduces the physical amount of storage required to save a dataset. |
File Storage Resources | File Systems (NFS, SMB) and VMware NFS Datastores. |
Flash drive (SSD) | A Flash based storage device used to store data. |
Hard Disk Drive (HDD) | A storage device based on spinning platters used to store data. |
Hybrid Pool | A Pool which does not contain only Flash Drives. A Hybrid Pool typically contains more than one type of drive technology, such as Flash, SAS, and NL-SAS. |
LUN | A block based storage resource which a user provisions. It represents a SCSI logical unit. |
Pool | A set of drives that provide specific storage characteristics for the resources that use them, such as LUNs, VMware Datastores, and File Systems. |
REST API | An application programming interface that utilizes familiar HTTP operations like GET, POST, and DELETE. REST architecture includes certain constraints that ensure that different implementations of REST conform to the same guiding principles, thereby allowing developers the ease of application development when working with different REST API deployments. |
Snapshot | A snapshot also called a Dell Unity Snapshot, is a point-in-time view of a storage resource. When a Snapshot is taken, the snapshot is an exact copy of the source storage resource and shares all blocks of data with it. As data changes on the source, new blocks are allocated and written to. Dell Unity Snapshot technology can be used to take a snapshot of a Block or File storage resource. |
Storage Resource | An addressable and configurable storage instance associated with a specific quantity of storage. LUNs, File Systems, and VMware Datastores constitute storage resources. |
System Cache (DRAM Cache) | Dell Unity software component which leverages DRAM memory to improve host read and write performance. |
Thin Clone | A read/write copy of a Thin Block storage resource (LUN, Consistency Group, or VMware VMFS Datastore) that shares blocks with the parent resource. |
Unisphere | A web-based management environment used to create storage resources, configure and schedule protection for stored data, and manage and monitor other storage operations. |
Unisphere CLI (UEMCLI) | The command line interface for managing Dell Unity storage systems. |
