With the development of global optical communication networks, optical transceiver modules in the field of optical communications is increasingly important position significantly, and optical communication technology is the modular, high-speed, integrated, multi-application, multi-function, flexibility , the direction of the development of low-cost, high-speed, high-quality optical fiber communication has become an inevitable trend in the development of the information industry.
Fiber Channel (Fiber Channel) is a switching network storage technology to provide long-range and high-bandwidth transmission can be realized between the large data files in a memory, the server and the client node. Normal operating speed has 2Gbps, 4Gbps, 8Gbps, 16Gbps, 32Gbps, 64Gbps and 128Gbps, used to connect a computer storage device. In the past, mostly for Fiber Channel supercomputer, but it has also become a common connection type enterprise storage SAN. Although Fiber Channel is called, but it can also be a signal other than the run on twisted fiber.
Fiber Channel optical module was used in the data center Fiber Channel storage network link, compatible with Ethernet optical transceiver module, InfiniBand FDR / EDR and OTN optical transport network. It includes a transmitter, receiver, and control the clock data recovery part. Fiber Channel optical module can be backward compatible applications Fiber Channel, and to support the optical loopback circuit path loopback diagnostic testing, to provide a stable receiving alarms. As an interface between the system interface between the Fiber Channel storage network and optical storage devices, miniaturization, low power consumption, can be improved by density port; hot swappable, easy debugging system site, can be achieved without replacing the light down module; support for digital diagnostic interface, network management can monitor the working condition through the communication interface optical module.
Why is the data center to be used fibre Channel storage network to do it?
1, the availability, the core business of data storage is not interrupted. So FC network to ensure that data can always be accessed. So availability is the first one.
2, performance, core business is increasingly high performance requirements. fibre Channel provides better performance.
3, scalability, FC network can guarantee service expansion, increase in size, increase the storage capacity, a corresponding underlying network, systems capable of supporting such services. The SAN network that can do this.
4, security, fibre Channel is a natural safety system. A can to inside the data center network ID, to your server above. Because our SAN network is a natural with the outside world, so it is not possible to go inside your storage network. SAN data can be protected through the network, reducing the risk of data leakage.
End is particularly important for the whole array of flash memory such as a flash new technologies are driving data center transformation speed is high with respect to the IO, the demand for high-performance, Fiber Channel 6th generation. When companies use flash memory to redesign their data centers, optimize application performance, they need to be able to provide low-latency network, high-capacity bandwidth and reliability. At present, 70-80% of the flash array using fiber channel storage systems have been deployed. In the future, it will be integrated with current and future generation of Fiber Channel network 6 based on non-volatile memory seamlessly standard (the NVMe) next-generation flash memory.
