Storage Area Network

Storage area networks (SANs) are the most common storage networking architecture used by enterprises for business-critical applications that need to lớn 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, và lower total cost when compared to lớn spinning disk. By storing data in centralized shared storage, SANs enable organizations to lớn apply consistent methodologies & tools for security, data protection, & disaster recovery.

A SAN is block-based storage, leveraging a high-speed architecture that connects servers khổng lồ their logical disk units (LUNs). A LUN is a range of blocks provisioned from a pool of shared storage & presented khổng lồ the server as a logical disk. The server partitions và 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 3d about two-thirds of the total networked storage market. They are designed lớn remove single points of failure, making SANs highly available and resilient. A well-designed SAN can easily withstand multiple component or device failures.

SAN Use Cases

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

Types of SAN

The most common SAN protocols are:

Fibre Channel Protocol (FCP). The most widely used SAN or block protocol, deployed in 70% to 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% to lớn 15% of the market. ISCSI encapsulates SCSI commands inside an Ethernet frame and then uses an IP Ethernet network for transport.Fibre Channel over Ethernet (FCoE).

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

SAN vs. NAS

Both SAN và 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 & Fibre Channel. In addition, while SAN focuses on high performance and low latency, NAS focuses on ease of use, manageability, scalability, và lower total cost of ownership (TCO). Unlike SAN, NAS storage controllers partition the storage and then own the tệp tin system. Effectively this makes a NAS hệ thống look like a Windows or UNIX/Linux hệ thống to the server consuming the storage.
