实验目的：用四块磁盘，建立两个镜像，然后将这两个镜像做成stripe。 一、建立8个子磁盘 root@server42 # vxmake -g testdg sd subdisk09 testdg01,4194304,1g root@server42 # vxmake -g testdg sd subdisk10 testdg02,4194304,1g root@server42 # vxmake -g testdg sd subdisk11 testdg03,4194304,1g root@server42 # vxmake -g testdg sd subdisk12 testdg04,4194304,1g root@server42 # vxmake -g testdg sd subdisk13 testdg...
下面这篇文章介绍的比较详细 http://www.pcguide.com/ref/hdd/perf/raid/concepts/perfstripe-c.html stripe Width and stripe Size RAID arrays that use striping improve performance by splitting up files into small pieces and distributing them to multiple hard disks. Most striping implementations allow the creator of the array control over two critical parameters that define the way that the data is ...
串联与条带 A simple metadevice is a metadevice built only from slices, and is either used directly or as the basic building block for mirrors and trans metadevices. There are three kinds of simple metadevices: concatenated metadevices, striped metadevices, and concatenated striped metadevices. A concatenated metadevice, or concatenation, is a metadevice whose data is organized serially and adjac...

不知道这样做性能上面会不会有提供， 想通过squid给图片服务器做反向代理， squid服务器配置如下CPU：双核双至强Xeon3.2，内存：2G，硬盘：600G ata RH-E4/i386 squid2.7 http_port 80 vhost vport icp_port 3130 cache_mem 1024 MB cache_effective_user squid cache_effective_group squid dns_nameservers 202.106.0.20 cache_access_log /squidfiles/logs/access.log cache_log /squidfiles/logs/cache.log cache_store_l...
做raid的时候一般有个条带大小可以选择这个大小和具体的应用的性能有很大的关系，一般数据库比较小的条带性能会比较好，像视音频比较大的条带性能会好点，谁能从原理上说一下为什么是这样
How to Expand a File System With a Single stripe, On the Fly First, the file system has to be created and mounted as a one-way mirror metadevice; as in this example, with d80 mounted by /opt: # metastat d80 d80: Mirror Submirror 0: d81 State: Okay Pass: 1 Read option: roundrobin (default) Write option: parallel (default) Size: 10261520 blocks d...
