SAN multi-protocol routers solve SAN access problems

SAN multi-protocol routers solve SAN access problems. a san Based on Fiber Channel can transmit data at a high speed of 200 Mb/s. An important difference between an optical fiber channel and other network protocols is its data transfer bandwidth utilization. In an Optical Fiber Channel architecture, the bandwidth utilization can easily reach more than 99%. This is incomparable to other existing network protocols. Fiber Channel can extend the SAN connection distance to over 100 kilometers. If the protocol conversion technology (for example, the conversion from the fiber channel to the SONET and the conversion from the fiber channel to the IP address) is supplemented, the SAN connection distance can reach the global range. A Fabric consisting of fiber channel switches connected to each other can connect 239 fiber channel switches with up to 24-bit device address space. Compared with Ethernet, fiber channel data transmission in the same Fabric is device-to-device, while data transmission in the same Ethernet Subnet is broadcast. This is the main reason why fiber channel bandwidth usage is several times higher than that of Ethernet. It is precisely because the data transmission device of the Optical Fiber Channel in the same Fabric is opposite to the device, and the optical fiber channel stipulates a strict system to constitute a management system. In the management system of this system, the access and removal of devices, including fiber channel switches, are broadcast to devices that communicate with the access and removal devices in the form of broadcast. Www.2cto.com today has hundreds of thousands of SAN islands in the world. Users often need to integrate these SAN islands. If this integration is integrated into a Fabric, the customer will face complicated operations such as adjusting the Fiber Channel switch parameters and rewriting the system composition files on some servers. In many cases, the customer cannot even arrange enough scheduled downtime to complete such system integration. Fiber Channel SAN Fabric lacks the means to connect low-end servers to SAN.
When using FCIP for a remote disaster recovery system, you must use a separate SAN-to-FCIP conversion device, in addition, a SAN Fabric is formed between the local and remote SAN connected through an IP network, which greatly limits the availability of the SAN by the availability level of the long-distance IP connection. Fiber Channel SAN multi-protocol routers emerged under such a historical condition. The basic feature of a Multi-Protocol Fiber Channel SAN router is that it connects Fabric, which is not connected to each other so far, and maintains the Fabric independence of each Fabric. To expand SAN connectivity, SAN multi-protocol routers also provide FCIP and iSCS connection functions. Fiber Channel SAN multi-protocol routers bring the following benefits to network storage and Disaster Tolerance systems: the routes from www.2cto.com Fiber Channel to fiber channel realize seamless connection between SAN Fabric. Do not modify the existing Fabric parameters when connecting different Fabric. At the same time, the access of the router will not affect the ongoing IO. The SAN multi-protocol router realizes the resource sharing between Fabric, especially the sharing of tape libraries between Fabric. It broke through the limit of 239 fiber channel switches/Fabric in SAN. This makes a large-scale SAN network possible. It provides a perfect storage network architecture for the implementation of multi-point disaster recovery systems. In the disaster recovery system, the use of SAN multi-protocol routers can isolate local and remote SAN Fabric, greatly improving the data availability and system reliability of the disaster recovery system. Multi-Fabric ensures the autonomy of SAN network management in different departments of the same company through the interconnection of SAN multi-protocol routers, and improves the degree of freedom of SAN Development in different departments. It greatly simplifies the difficulty of supporting SAN Fabric services provided by different vendors. The SAN multi-protocol router provides the iSCSI connection function, which provides an effective way for low-end servers to connect to the high-end SAN Fabric through www.2cto.com SAN multi-protocol router to provide the FCIP function. The combination of the routing function and the FCIP function makes the local disaster recovery system that uses the FCIP for long-distance connection, and the Remote SAN becomes two different Fabric. this greatly improves the availability of the Disaster Recovery System Connected by FCIP.
The emergence of SAN multi-protocol routers is a revolutionary event in the network storage industry. Its emergence makes multi-point to multi-point Disaster Tolerance difficult to achieve in the past a reality. Its Applications can greatly improve the availability and reliability of the disaster recovery system. SAN multi-protocol routers also make the seamless interconnection between Fabric a reality, which greatly simplifies the design of SAN and the complexity of data migration in the SAN system. SAN multi-protocol routers organically combine fiber channel networks and IP networks to expand SAN connectivity. In the near future, we can see a large-scale SAN composed of a SAN multi-protocol router connected to multiple SAN Fabric. we can also expect SAN multi-protocol routers to be used in various types of disaster recovery systems. SAN multi-protocol routers will also become an indispensable tool for data migration in heterogeneous environments.
