FC optical fiber card

Abstract

The FC optical fiber card comprises a mainboard connector, a signal conversion circuit and a plurality of output connectors, wherein the mainboard connector is used for being connected with a mainboard; the signal conversion circuit is used for dividing a PCIE signal of the mainboard into multiple paths of FC signals; wherein the total number of the output optical ports of the plurality of outputconnectors is a positive integer greater than 4; the mainboard connector is connected with the signal conversion circuit; the signal conversion circuit is respectively connected with each output connector, and each output connector corresponds to one FC signal sent by the signal conversion circuit; the PCIE signal of the mainboard is divided into multiple paths of FC signals by using the signal conversion circuit, through cooperation with the plurality of output connectors, the total number of the output optical ports of the FC optical fiber card is a positive integer larger than 4, the numberof the output optical ports of the FC optical fiber card is increased, the capacity of cascading JBOD of the FC optical fiber card is improved, the expansibility is better, and meanwhile, the size ofthe FC optical fiber card can be ensured not to be increased.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to an FC fiber card. Background technique [0002] With the development of human society, the amount of data in the world is increasing substantially, and the capacity requirements of enterprises for storage systems are also increasing, which requires cascading more and more JBODs (Just a Bunch OfDisks, Disk Expansion Cabinet). The storage controller and JBOD are usually cascaded using FC fiber cards (FC, Fiber Channel, Fiber Channel). At present, the more mature FC fiber cards on the market are basically 2-port and 4-port FC fiber cards. Its expansion capability is also limited, and it is difficult to meet the demand for large-capacity storage. [0003] Based on the above problems, it is necessary to propose an FC fiber card with a stronger capability of cascading JBODs. Contents of the invention [0004] In view of this, the purpose of the present invention is to pro...

The storage controller and JBOD are usually cascaded using FC fiber cards (FC, Fiber Channel, Fiber Channel). At present, the more mature FC fiber cards on the market are basically 2-port and 4-port FC fiber cards. Its expansion capability also has a certain limit, and it is difficult to meet the storage requirements of large capacity.
