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.

Abstract
The invention discloses a design scheme of SAS Switch/JBOD topology. According to the scheme, a SAS Switch board and a control hard disk constitutes a storage structure which particularly comprises 1, a Rack computing server, 2, a SAS Switch node and 3, a JBOD node. According to the design scheme of the SAS Switch/JBOD topology, arrangement and pooling for computing source and storage resource are conducted through optimization of the whole structure, both solving expensive price of storage and dependence of storage server on server, so a novel structure takes shape, which meets application of client for distributed storage, mainly Hadoop structure, saves cost and is relatively high in flexibility, thus the amount of equipment can be flexibly adjusted according to demand of integral application.
Description
technical field [0001] The invention relates to the technical field of computer storage, in particular to a design scheme of a SAS Switch / JBOD topology. Background technique [0002] At present, the storage industry is paying a lot of attention to hyper-converged storage (for example: Nutanix, VMWare VSan) or Server SAN technology. This type of technology is undergoing high-growth development. Serious impact on traditional SAN and storage systems. [0003] Due to its high price, the original storage device has received great resistance in the use of end users, and the end customer needs to purchase a large number of devices for the construction of the storage architecture. The cost of storage architecture, especially optical fiber storage, is basically high, and customers rely heavily on equipment. Considering cost balance, distributed storage has become the first choice for large storage application manufacturers. [0004] The emergence of Hadoop, a typical application ...
