Abstract

The invention discloses a cascade plate, an SSD remote sharing visit system and method and belongs to the field of communication. One end of the cascade plate is connected with an RDMA network and the other end is connected with an SSD; the cascade plate comprises a visit processing device and a CPU coupled with the visit processing device; the CPU is used for initialization of the visit processing device and the SSD; the visit processing device can implement an RDMA access to the SSD when receiving a visit order from the RDMA network. The cascade plate can be applied for SSD remote sharing visit.

Description

technical field [0001] The invention relates to the communication field, in particular to a system and method for cascading boards and SSD remote shared access. Background technique [0002] Solid State Drive (SSD) is a hard disk made of an array of solid-state electronic memory chips. SSD has been welcomed by more and more people because of its advantages such as fast read and write speed, low power consumption, and light weight. [0003] At present, with the continuous improvement of SSD capacity and performance, people are paying more and more attention to sharing a single or a group of SSDs with various other devices connected through the network, so as to make full use of the various characteristics of SSDs. [0004] Related technologies In the process of realizing remote shared access to SSD, the remote device's access to SSD will be processed by a processor (CPU). That is, the processor receives an SSD access command from a Remote Direct Memory Access (RDMA) network...
