Technical field
The present invention relates to computer memory technical field, the SAS Switch design methods of specifically a kind of redundancy.
Background technology
Storage industry is to super fusion storage at present（Such as： Nutanix, VMWare VSan）Or Server SAN
Technology have many concerns.This kind of technology is undergoing the development of rapid growth.Traditional SAN and storage system are caused
Serious impact.
Former storage device have received larger resistance, final visitor due to its expensive price in the use of end user
Family needs to buy substantial amounts of equipment building for storage architecture.Storage architecture especially optical fiber stores, and cost is substantially all very high,
Client is larger for the dependence of equipment.In balance cost consideration, distributed storage turns into the first choice that producer is applied in large-scale storage.
Distributed storage typical case Hadoop appearance is realized for traditional larger impact that has been stored with, Hadoop
One distributed file system（Hadoop Distributed File System）, abbreviation HDFS.HDFS has high fault tolerance
The characteristics of, and be designed to be deployed in cheap（low-cost）On hardware；And it provides high-throughput（high
throughput）Carry out the data of access application, be adapted to those to have super large data set（large data set）Application
Program.HDFS is relaxed（relax）POSIX requirement, it can access in the form of streaming（streaming access）File system
Data in system.
Storage server is a kind of storage device between storage and server, is designed for specific objective, because
This configuration mode is also different.It is probably to possess a little extra storage, it is also possible to possess very big memory space, relative storage
There is certain progress, but because its restricted server platform, its framework follow server development platform, for magnanimity deployment
For client, it still there is larger framework to limit.

Further, preferable structure is that the quantity of described SAS Switch storage systems is 2-9.
Further, the SAS Switch design methods of the invention for also protecting a kind of redundancy, method are as follows：Rack calculates clothes
Business device connects two SAS Switch nodes simultaneously, and two SAS Switch nodes cascade with three JBOD nodes respectively simultaneously.
Compared to the prior art a kind of SAS Switch design methods of redundancy of the present invention, have the beneficial effect that：
1st, the present invention is carried out arranging pond for computing resource and storage resource, had both been solved and deposited by the optimization of whole framework
The expensive price of storage, solve the dependence for server of storage server again, realize super fusion storage architecture；
2nd, it is mainly answering for Hadoop framework for distributed storage that the present invention, which turns into a new framework to be compounded with customers' place,
With cost, and the higher number that equipment can be adjusted flexibly according to the demand of overall applicability of flexibility ratio saved again, has been improved
Reliability of the product in service application；
3rd, the present invention is prevented because the damage of an equipment, is influenceing service application just by SAS Switch Redundancy Design
Often use, and can be started by remote command and backed up, without attendant's execute-in-place, greatly improve maintenance efficiency；
4th, it is widely used in the products such as company Rack, enriches product line, huge benefit is brought to company.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is a kind of structured flowchart of the SAS Switch design methods of redundancy.
Embodiment
