Software-Defined Storage SDS

Software-Defined Storage SDS Software-Defined Storage SDS: Storage infrastructure that is managed and automated by intelligent software as opposed to by the storage hardware itself. In this way, the pooled storage infrastructure resources in a software-defined storage (SDS) environment can be automatically and efficiently allocated to match the application needs of an enterprise. Separating the Storage Hardware from the Software By separating the storage hardware from the software that ma...

Storage Virtualization Definition

Storage Virtualization Definition Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization helps the storage administrator perform the tasks of backup, archiving, and recovery more easily -- and in less time -- by disguising the actual complexity of a storage area network (SAN).  Administrators can implement virtualization with software app...

Storage Networking

Storage Networking Storage networking is the practice of linking together storage devices and connecting them to other IT networks. Storage networks provide a centralized repository for digital data that can be accessed by many users, and they use high-speed connections to provide fast performance. It's most common to find storage networks in enterprise settings, although some vendors do sell networked storage products for consumers and small businesses. Storage Networking and SAN The phr...

Storage Area Network (SAN)

Storage Area Network (SAN) 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. A SAN moves storage resources off the common user network and reorganizes them into an independent, high-performance network. This allows each server to access shared storage as if it were a drive directly attached to the server. When a host wants to access a storage device on the SAN, it sends out a...

Automated Storage Tiering (AST)

Automated Storage Tiering (AST) Automated storage tiering (AST) is a storage software management feature that dynamically moves information between different disk types and RAID levels to meet space, performance and cost requirements. Automated storage tiering features use policies that are set up by storage administrators. For example, a data storage administrator can assign infrequently used data to slower, less-expensive SATA storage but allow it to be automatically moved to h...

Thin Provisioning

Thin Provisioning Thin provisioning (TP) is a method of optimizing the efficiency with which the available space is utilized in storage area networks (SAN). TP operates by allocating disk storage space in a flexible manner among multiple users, based on the minimum space required by each user at any given time. In the conventional storage provisioning model, also known as fat provisioning (FP), storage space is allocated beyond current needs, in anticipation of growing need and increased...

Disaster Recovery Definition

Disaster Recovery Definition Disaster recovery (DR) is an area of security planning that aims to protect an organization from the effects of significant negative events. DR allows an organization to maintain or quickly resume mission-critical functions following a disaster. A disaster can be anything that puts an organization's operations at risk, from a cyberattack to equipment failures to natural disasters. The goal with DR is for a business to continue operating as close to normal as ...
