A storage area network (SAN) is a dedicated network that is tailored to a specific environment—combining servers, storage systems, networking switches, software and services. Why storage area networks are important. Computer memory and local storage resources might not provide enough storage, storage protection, multiple-user access, or speed ...
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 .

SAN storage has been around for many years. But several factors are making this network-based storage solution more important than ever for everyday business use. For example: 1. Organizations need to provide users reliable access to data at all times. 2. Data of all types, structured and unstructured, is growing exponentially. 3. Cloud computing, ...
SANs provide any-to-any connectivity for servers and storage devices using Fibre Channel (FC) switches that are compatible with the FC protocol. FC SAN switches are used to connect devices within a SAN to create the SAN fabric. Routers, gateway devices, and cables that help the SAN interconnect servers with storage devices are also part of SAN fabr...
A SAN and network-attached storage (NAS) are both network-based storage solutions; however, a SAN is more complex. A SAN is a network that operates independently of an organization's operating system and is comprised of many different storage devices. It uses FC switches and stores data at the block level. To a client operating system, the SAN typi...
It doesn't have to be. If an organization already has the right SAN infrastructure in place, it can work with a leading provider of SAN technology to modernize its storage area network seamlessly and quickly, and without a major equipment upgrade. The business can also invest in today's SAN technology that can evolve to keep up with increasing appl...
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.
A Storage Area Network (SAN) is a dedicated, independent high-speed network that interconnects and delivers shared pools of storage devices to multiple servers. Each server can access shared storage as if it were a drive directly attached to the server. A SAN is typically assembled with cabling, host bus adapters, and SAN switches attached to ...
SAN vs. NAS. Both SAN and network-attached storage (NAS) are methods of managing storage centrally and sharing that storage with multiple hosts (servers). However, NAS is Ethernet-based, while SAN can use Ethernet and Fibre Channel. In addition, while SAN focuses on high performance and low latency, NAS focuses on ease of use, manageability ...
Aug 10, 2023 · Learn More . Storage area networks, or SANs, are a type of network to which multiple storage devices can be connected to provide networked users quick, reliable, and secure access to block-level storage. SANs rely on high-speed infrastructure to enable fast data transfer that mimics the experience of using local storage for end users.
