Storage architecture
Definitions about storage and data management including backup/recovery vocabulary, business intelligence terminology, storage area networks and database management.- TCP/IP - TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet.
- tebibyte (TiB) - A tebibyte (TiB) is a unit of measure used to describe computing capacity.
- Terabyte (TB) - A terabyte (TB) is a unit of digital data that is equal to about 1 trillion bytes.
- throughput - Throughput is a measure of how many units of information a system can process in a given amount of time.
- Tier 0 - Tier 0 is a level of data storage that is faster, and perhaps more expensive, than any other level in the storage hierarchy.
- tiered storage - Tiered storage is a method for assigning different categories of data to various types of storage media to reduce overall storage costs and improve the performance and availability of mission-critical applications.
- TLC flash (triple-level cell flash) - TLC flash (triple-level cell flash) is a type of NAND flash memory that stores three bits of data per cell.
- U.2 SSD (formerly SFF-8639) - A U.2 SSD is a high-performance data storage device designed to support the Peripheral Component Interconnect Express (PCIe) interface using a small form factor (SFF) connector that is also compatible with standard Serial-Attached SCSI (SAS) and Serial Advanced Technology Attachment (SATA)-based spinning disks and solid-state drives (SSDs).
- unified storage (multiprotocol storage) - Unified storage -- sometimes called network unified storage or multiprotocol storage -- is a storage system that makes it possible to run and manage files and applications from a single device.
- unzipping - Unzipping is the act of extracting the files from a zipped single file or similar file archive.
- utility storage - Utility storage is a service model in which a provider makes storage capacity available to an individual, organization or business unit on a pay-per-use basis.
- value chain - A value chain is a concept describing the full chain of a business's activities in creating a product or service -- from initial receipt of materials through its delivery to market.
- vector search - Vector search, sometimes referred to as vector similarity search, is a technique that uses vectors -- numerical representations of data -- as the basis to conduct searches and identify relevance.
- virtual disaster recovery - Virtual disaster recovery is a type of DR that typically involves replication and enables a user to fail over to virtualized workloads.
- virtual LUN (virtual logical unit number) - A virtual LUN (virtual logical unit number) is a representation of a storage area that is not tied to any physical storage allocation.
- volatile memory - Volatile memory is a type of memory that maintains its data only while the device is powered.
- wear leveling - Wear leveling is a process that is designed to extend the life of solid-state storage devices.
- Western Digital Corporation (WDC) - Western Digital Corporation (often referred to as WDC, Western Digital) is a data storage device manufacturer founded in 1970 and headquartered in San Jose, Calif.
- What is a SAN? Ultimate storage area network guide - A storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers.
- What is cloud management? Definition, benefits and guide - Cloud management refers to the exercise of control over public, private or hybrid cloud infrastructure resources and services.
- What is network-attached storage (NAS)? A complete guide - Network-attached storage (NAS) is dedicated file storage that enables multiple users and heterogeneous client devices to retrieve data from centralized disk capacity.
- Windows Server Failover Clustering (WSFC) - Windows Server Failover Clustering (WSFC) enables several computers to host a service, and if one has a fault, the remaining computers automatically take over the hosting of the service.
- World Wide Name (WWN) - A World Wide Name (WWN) is a unique identifier that is hard-coded into each Fibre Channel (FC) device by the device's manufacturer.
- write amplification factor (WAF) - Write amplification factor (WAF) is a numerical value that represents the amount of data a solid-state drive (SSD) controller writes in relation to the amount of data that the host's flash controller writes.
- write endurance - Write endurance is the number of program/erase (P/E) cycles that can be applied to a block of flash memory before the storage media becomes unreliable.
- zebibyte (ZiB) - A zebibyte (ZiB) is a unit used to measure computing and storage capacity.
