SAN SWITCH

Storage area networks (SANs) are the most common storage networking architecture used by enterprises for business-critical applications that need to deliver high throughput and low latency. A rapidly growing portion of SAN deployments leverages all-flash storage to gain its high performance, consistent low latency, and lower total cost when compared to spinning disk. By storing data in centralized shared storage, SANs enable organizations to apply consistent methodologies and tools for security, data protection, and disaster recovery. In a SAN, data is presented from storage devices to a host so that the storage looks like it is locally attached. This is achieved through various types of data virtualization. SAN storage, is a high-speed network that provides network access to storage. In some cases, SANs can be so large that they span multiple sites, as well as internal data centers and the cloud.

There are several benefits of SAN, include:

Availability
A duplicate of the data file can be directly accessed by almost all hosts via different channels and also all data will be much more efficient when managing it.

Reliability
Infrastructure in data transport that can minimize the error rate when transferring data, and also the ability to overcome all data transfer failures.

Scalability
Servers and storage media can also be added independently of one another, with no restrictions that must use a proprietary system.

Performance
Fiber Channel which is a standard enabling technology for interconnectivity SAN has a bandwidth up to 100MBps with relatively low overhead, and SAN will also separate the backup traffic process from the standard LAN or WAN traffic process.
