Storage system and method for concentration type system

Abstract

The invention relates to a storage system and method for a concentration type system. The storage system for the concentration type system comprises a requirement analysis module, a solid hard disc and a mechanical hard disc; wherein the requirement analysis module is used for analyzing the system index of data needed to be stored in the system and respectively sending the data into the solid hard disc and the mechanical hard disc for storage; the solid hard disc is used for storing data needed to be subjected to a large amount of reading and writing operation and frequent implementation of input and output operation; and the mechanical hard disc is used for storing backups or data with low time validity and limited random input and output. According to the storage system, the mechanic hard disc and the solid hard disc are used for layering storage, the characteristic of high I / O (input / output) of the solid hard disc can be maximally utilized; the dependence on a storage network is reduced, a local hard disc can be directly used for carrying out processing and backup of tickets, and the cost performance of a storage scheme is greatly improved; and the cost of construction and maintenance is lowered.

Description

technical field [0001] The invention relates to a storage system and method in an intensive system. Background technique [0002] In an I / O-intensive system, when a large number of concurrent I / O operations occur, the overall system performance will drop sharply, resulting in a large backlog of services and delays. Today, the performance of CPU and memory has been greatly improved, and tens / millions of reads and writes can be performed per second. The reason is that the performance of the hard disk data is reduced due to the reading and writing of hard disk data. Using a 15,000-rpm disk and increasing the cache cannot solve the problem. Traditional storage I / O performance becomes a bottleneck. [0003] Traditional mechanical hard drives do have their own advantages in application: large capacity, low price and relatively complete data protection system. However, due to its complex internal mechanical structure, it is necessary to continuously move the head arm to read data...

AI Technical Summary

Problems solved by technology

However, due to its complex internal mechanical structure, it is necessary to continuously move the head arm to read data on different platters (such as figure 1 shown), resulting in low read and write speeds and high latency for mechanical hard disks

[0004] However, although the existing enterprise-level FC (abbreviation for Fiber Channel, namely Fiber Channel) hard disk and SAS (abbreviation for Serial Attached SCSI, namely Serial Attached SCSI) hard disk have a speed of 15,000 rpm, the power consumption of the hard disk has reached the limit allowed by the computing system. The limit means that the mechanical hard disk has almost no room for performance improvement

[0005] In summary, traditional storage can no longer meet its performance requirements in random I / O-intensive systems and needs to be improved.
