Embodiment 1
[0059]In the HOST+JBOD architecture, HOST and JBOD transmit high-speed signals and sideband signals through cables. In order to reduce the number of sideband signals, JBOD needs BMC and CPLD to jointly manage JBOD. At this time, the BMC of HOST is the main BMC , the BMC of the JBOD is a slave BMC, and the master BMC communicates with the slave BMC through I2C to manage the JBOD. In a scenario where a single host has multiple JBODs, each JBOD requires a slave BMC to be connected to the master BMC through cables. This method occupies interface resources, increases the difficulty of layout wiring, and increases system hardware costs.
[0060] Therefore, this embodiment provides a single-host multi-disk cluster communication method, which implements communication between a single host and multi-disk clusters based on wireless communication technology, and solves the problems of insufficient interface resources, difficult layout routing, and high hardware cost.
[0061] Such as fi...
Embodiment 2
[0068] In order to further explain the present invention, this embodiment provides a single-host multi-disk cluster communication method, which realizes the monitoring and management of the disk cluster on the host side, not only realizes the pairing connection with the disk cluster to establish a data wireless communication channel, but also enables the disk cluster The pairing deletion of the cluster is managed, and in addition, when scanning the pairable disk cluster, it can be realized through the repeat timer.
[0069] Such as figure 2 Shown is a schematic flow chart of a single-host multi-disk cluster communication method provided in this embodiment, which is applied to the host side and includes the following method steps.
[0070] S201. The state-based detection thread periodically scans for pairable disk clusters.
[0071] It should be noted that the regular scan may specifically be a set scan period, and each scan period scans a pairable disk cluster once. For exa...
Embodiment 3
[0092] This embodiment provides a single-host multi-disk cluster communication device, which is applied to a host end and used to implement the foregoing single-host multi-disk cluster communication device.
[0093] Such as image 3 Shown is a schematic block diagram of the structure of a single-host multi-disk cluster communication device provided by this embodiment, including the following functional modules.
[0094] Scanning module 101: regularly scans pairable disk clusters based on state detection threads;
[0095] Connection request issuing module 102: if a pairable disk cluster is scanned, a connection request is sent to the pairable disk cluster;
[0096] The connection request feedback receiving module 103: receives the connection request feedback and completes the pairing connection with the pairable disk cluster, and establishes a data wireless communication channel;
[0097] The communication module 104: communicates with the corresponding disk cluster based on ...
