Description

一种基于龙芯处理器的提高软RAID性能的方法A Method of Improving Soft RAID Performance Based on Loongson Processor

技术领域 technical field

本发明涉及一种计算机通信技术领域，具体地说是一种基于龙芯处理器的提高软RAID性能的方法。 The invention relates to the technical field of computer communication, in particular to a method for improving soft RAID performance based on a Godson processor.

背景技术 Background technique

RAID就是把几个物理磁盘组合在一起成为一个大的虚拟物理磁盘，主要目的和用途有：把若干小容量物理磁盘组成一个大容量虚拟存储设备（以前的物理磁盘的容量都比较小），提高物理存储效率（读、写）或提供冗余以提高数据存储的安全性。 RAID is to combine several physical disks together to form a large virtual physical disk. The main purposes and uses are: to combine several small-capacity physical disks into a large-capacity virtual storage device (the capacity of the previous physical disks was relatively small), improve Physical storage efficiency (read, write) or provide redundancy to increase the security of data storage.

RAID 还分为硬件RAID 和软件RAID，硬件RAID是通过RAID 卡来实现的，而软件RAID是通过软件来实现的；在企业级应用领域，大部份都是硬件RAID。而软件RAID由于性价比高，大多被中小型企业所采用。硬件RAID是通过RAID卡把若干同等容量大小的硬盘，根据使用方向的不同，聚合起来成为一个大的虚拟RAID设备（或RAID0，或RAID1,或者RAID5，或RAID10……），如果每个硬盘容量不一致，以最小容量的硬盘为基础；它的成员是整个硬盘。 RAID is also divided into hardware RAID and software RAID. Hardware RAID is realized through RAID cards, while software RAID is realized through software; in the field of enterprise-level applications, most of them are hardware RAID. However, software RAID is mostly adopted by small and medium-sized enterprises due to its high cost performance. Hardware RAID is to aggregate a number of hard disks with the same capacity through the RAID card, depending on the direction of use, to form a large virtual RAID device (or RAID0, or RAID1, or RAID5, or RAID10...), if the capacity of each hard disk Inconsistent, based on the smallest hard drive; its members are entire hard drives.

软RAID是把若干同等容量大小的硬盘或分区，根据使用方向的不同，聚合起来成为一个大的虚拟RAID设备（或RAID0，或RAID1,或者RAID5，或RAID10……），如果每个硬盘或分区容量不一致，以最小容量的硬盘或分区为基础。软RAID的成员是整个硬盘或分区。 Soft RAID is to aggregate several hard disks or partitions with the same capacity and size according to different usage directions to form a large virtual RAID device (or RAID0, or RAID1, or RAID5, or RAID10...), if each hard disk or partition The capacity is inconsistent, based on the hard disk or partition with the smallest capacity. Members of soft RAID are entire hard disks or partitions.

传统的创建软RAID方法如附图1所示，是在南桥芯片上挂接多个SATA硬盘再经过北桥芯片与龙芯处理器通信，这样用户在建立RAID的过程中需要跨越两级路径。这就会降低构建软RAID的存储效率，实现不同级别的软RAID功能较为繁琐。 The traditional method of creating a soft RAID is shown in Figure 1. Multiple SATA hard disks are attached to the south bridge chip and then communicate with the Godson processor through the north bridge chip. In this way, the user needs to cross two levels of paths in the process of creating a RAID. This will reduce the storage efficiency of constructing soft RAID, and it is more cumbersome to implement different levels of soft RAID functions.
