Study Notes for storage routers and SAN Routers

There are still many things worth learning about storage routers. Here we will mainly introduce the study notes of storage routers and SAN routers. The continuous development of enterprises will generate massive data, and these extended massive information must be stored and managed.

In the process of storage, although servers and storage devices provide good storage performance, as a interconnect device in the network, it is often the bottleneck restricting data storage. On the other hand, an enterprise is often used to dividing the entire network into different network segments, forming multiple independent Storage Network SAN), which makes network storage in different departments a lot of barriers. In this case, the Storage Router products specially designed for storage have emerged.

Understanding storage Routers

Actually, the Storage Router mentioned here should be called the Storage Router accurately. SAN can be seen as an extension of the concept of storage bus. It uses LAN) and WAN) similar units to achieve interconnection between storage devices and servers. These units include: storage routers, hubs, switches, and gateways ). A san can be shared between servers or private to a server. It can be a local storage device or be expanded to other places in a geographical region.

This is not difficult to introduce the essence of the Storage Router. It is actually a device that enables users to connect to the storage environment on a standard data network. Note that these devices are not used to directly connect devices to the LAN or enterprise backbone network, but to build an independent network infrastructure for the storage network. Its main feature is to greatly improve the data availability, overall reliability and stability of the Disaster Tolerance System. The connection between multiple SAN storage systems built using storage routers is as follows.

In addition, the Storage Router differs from the network router in that the router data is routed using a storage protocol such as FCIPFC over IP, rather than a communication protocol such as TCP/IP. From the basic functions of the Storage Router described above, FCIP storage protocol allows devices in different SAN to establish communications without merging these devices into a large SAN; it also allows you to establish a storage system from any device to any device.
