Iometer学习笔记二：详解“Disk Target Tab” 勘误

源文https://community.emc.com/docs/DOC-24663

     近日查看iometer的文章，发现以下翻译错误：

# of Outstanding I/Os per target – 被选中worker的每个磁盘一次所允许的未处理的异步I/O的数量。（注意：如果操作完成的非常快，磁盘实际看到的队列深度可能更少，默认值是1）举个例子：假设选中了一个Manager，选中8个Disk，指定# of Outstanding I/O of =16，磁盘被分布到咯咯worker（每个worker分到2个disk），每个worker对其下的每一个disk生成最大16个未处理I/O，那么整个系统中该Manager每次将生成最多128个未处理I/O（4 worker * 2disk/worker * 16未处理I/O/disk）。

    查看官网Iometer user's guide,如下：

Note that the value of this control applies to each selected worker and each selected

disk. For example, suppose you select a manager with 4 disk workers in the Topology

panel, select 8 disks in the Disk Targets tab, and specify a # of Outstanding I/Os of 16.

In this case, the disks will be distributed among the workers (2 disks per worker), and

each worker will generate a maximum of 16 outstanding I/Os to each of its disks. The

system as a whole will have a maximum of 128 outstanding I/Os at a time (4 workers *

2 disks/worker * 16 outstanding I/Os per disk) from this manager.

 

一个manager 4个worker没有翻译
