A virtual storage area network (virtual SAN, VSAN or vSAN) is a logical representation of a physical storage area network (SAN). A VSAN abstracts the storage-related operations from the physical storage layer, and provides shared storage access to the applications and virtual machines by combining the servers' local storage over a network into a single or multiple storage pools.
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage.SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage.
The IBM 2145 SAN Volume Controller (SVC) is an inline virtualization or "gateway" device. It logically sits between hosts and storage arrays, presenting itself to hosts as the storage provider (target) and presenting itself to storage arrays as one big host.
In computer science, storage virtualization is "the process of presenting a logical view of the physical storage resources to" [1] a host computer system, "treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage."
This is a list of Storage area network (SAN) management systems. A storage area network is a dedicated network that provides access to consolidated, block level data storage. Systems
Hitachi Command Suite (formerly Hitachi Storage Command Suite) provides integrated storage resource management, tiered storage and business continuity software. [9] Hitachi Command Suite employs a use case-driven, step-by-step wizard-based approach that allows administrators to perform tasks such as new volume provisioning, configuration of external storage, and creation/expansion of storage ...
Although blade-server technology in theory allows for open, cross-vendor systems, most users buy modules, enclosures, racks and management tools from the same vendor. Eventual standardization of the technology might result in more choices for consumers; [ 13 ] [ 14 ] as of 2009 [update] increasing numbers of third-party software vendors have ...
While a SAN makes available several devices and/or ports to a single device, each system connected to the SAN should only be allowed access to a controlled subset of these devices/ports. Zoning applies only to the switched fabric topology (FC-SW), it does not exist in simpler Fibre Channel topologies.
