Storage Area Network

Storage area networks (SANs) are the most comtháng 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 lớn 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 khổng lồ apply consistent methodologies & tools for security, data protection, and disaster recovery.

A SAN is block-based storage, leveraging a high-speed architecture that connects servers lớn their logical disk units (LUNs). A LUN is a range of blocks provisioned from a pool of shared storage và presented khổng lồ the VPS as a logical disk. The VPS partitions & formats those blocks—typically with a tệp tin system—so that it can store data on the LUN just as it would on local disk storage.

SANs hóa trang about two-thirds of the total networked storage market. They are designed khổng lồ remove single points of failure, making SANs highly available and resilient. A well-designed SAN can easily withst& multiple component or device failures.

SAN Use Cases

Storage area networks are frequently deployed in tư vấn of business-critical, performance-sensitive sầu applications such as:

Types of SAN

The most common SAN protocols are:

Fibre Channel Protocol (FCP). The most widely used SAN or bloông xã protocol, deployed in 70% lớn 80% of the total SAN market. FCP uses Fibre Channel transport protocols with embedded SCSI commands.Internet Small Computer System Interface (iSCSI). The next largest SAN or block protocol, with approximately 10% khổng lồ 15% of the market. iSCSI encapsulates SCSI commands inside an Ethernet frame và then uses an IPhường Ethernet network for transport.Fibre Channel over Ethernet (FCoE).

FCoE is less than 5% of the SAN market place. It is similar to lớn iSCSI, since it encapsulates an FC frame inside an Ethernet datagram. Then like iSCSI, it uses an IP.. Ethernet network for transport.


Both SAN & network-attached storage (NAS) are methods of managing storage centrally và 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 và low latency, NAS focuses on ease of use, manageability, scalability, & lower total cost of ownership (TCO). Unlượt thích SAN, NAS storage controllers partition the storage và then own the tệp tin system. Effectively this makes a NAS VPS look like a Windows or UNIX/Linux server to the server consuming the storage.
