Embodiment 1
[0021] Such as figure 1 As shown, a SAS Switch / JBOD topology design scheme, the scheme is connected and controlled by a SAS Switch board to form a storage architecture with 240 hard disks, specifically including: (1) Rack computing server, (2) SAS Switch nodes, ( 3) JBOD nodes, where:
[0022] (1), Rack computing server: Computing server suitable for Smart Rack cabinets, including SERVER 1, SEVER2, ..., SERVER N;
[0023] (2), SAS Switch node: Install the SAS Switch module for the forwarding and processing of SAS signals;
[0024] (3) JBOD node: used to connect storage devices (hard disks, SSDs, etc.), snap JBOD 1, JBOD 2, ..., JBOD M, each node can connect up to 64 SAS / SATA HDD / SSD.
[0025] JBOD is an important type of storage device in the storage field. JBOD (Just a Bunch Of Disks, disk cluster) is a storage device with multiple disk drives installed on a backplane. Usually also known as Span. Unlike RAID arrays, JBODs have no front-end logic to manage the distributio...
Embodiment 2
[0027] On the basis of Embodiment 1, the management client MANAGEMENT CLINT of this embodiment is connected to the SAS Switch node through Ethernet network / UART / I2C to control and use the storage architecture.
Embodiment 3
[0029] On the basis of Embodiment 1, the Rack computing server described in this embodiment is connected to the SAS Switch node through the SAS HBA card.
