VNXe 效能IOPS?

Hi 各位前輩

抱歉我又來打擾問問題了！

   

請問一下！針對VNXe效能部分 有任何工具針對像是iops分析的工具嗎？

更細節的報告, 該怎麼收log等等的

如同vnx analyzer這類的軟體

麻煩各位了！

Hey Lin,

据我所知，VNXe上暂时还没有分析IOPS性能的工具。

当前，在Unisphere-> System -> System Performance 页面下只集成了 CPU, Network和Volume等的活动情况.

其实IOPS方面的数据一般都是根据现在实际的情况测试出来的。因为IOPS的结果根据磁盘类型（SAS，NL-SAS，SSD或闪存等），磁盘容量大小，RAID类型等的不同结果也不同。所以说，实测为王嘛~~

我这里找到一个在线计算IOPS的网站，你可以在你的实际环境中测试一下。

这个在线计算IOPS网站还不错，支持各种常见RAID，和多种型号硬盘，如SSD。你可以参考一下。

除了上面这个，最常用的IOPS的测试benchmark工具主要有Iometer, IoZone等，这些可以综合用于测试磁盘在不同情形下的IOPS。下面的磁盘IOPS数据来自http://en.wikipedia.org/wiki/IOPS，给你一个基本参考。

Examples

Some com­monly accepted aver­ages for random IO operations, calculated as 1/(seek + latency) = IOPS:

Device Type IOPS Interface Notes
7,200 rpm SATA drives HDD ~75-100 IOPS[2] SATA 3 Gbit/s
10,000 rpm SATA drives HDD ~125-150 IOPS[2] SATA 3 Gbit/s
10,000 rpm SAS drives HDD ~140 IOPS[2] SAS
15,000 rpm SAS drives HDD ~175-210 IOPS[2] SAS

收到！！

因為我自己在support.emc or powerlink 也是沒看到相關方式

現在似乎只能在unisphere vnxe system performance內看到cpu, network, volume r/w


謝謝Leo

不客气。。

我还找到了一些VNXe上IOPS相关的一些数据，你可以参考一下。正如下面所说，仅供参考哦~

Below is an ESTIMATE of IOPS of a drive based on their rotation speed:

Disk TypeDisk CapacityRPMIOPS
Flash100GB, 200GBN/A6000
SAS300GB, 600GB15k170-180
SAS900GB10k125
NL SAS1TB, 2TB, 3TB720075

Note: The above stats were calculated in a controlled lab environment and are only for providing a general reference. These should in no way be used as a benchmark.

Hey Lin,

我找到了一些用户在实际环境中用IO Meter测试VNXe性能的结果，这个可能对你帮助更大。具体内容，你可以参考下面这个帖子。

IO Meter Performance Stats?

用户1：

I ran through the iometer tests on the vmktree iso and below are the results from an NFS share.  The first result is with the NFS share cached which is the wrong behavior.  The second test being after the MR1 install with the cache turned off.  On the Max Throughput-50% read it is taxing the 1Gb connection now.  My numbers are not overly scientific given that there are 20 VM's running on the 3100 as I ran the test but the performance difference is substantial for those of you fighting with NFS performance.

Test name Latency Avg iops Avg MBps cpu load
Max Throughput-100%Read 16.07 3694 115 3%
RealLife-60%Rand-65%Read 128.02 435 3 10%
Max Throughput-50%Read 25.20 2352 73 2%
Random-8k-70%Read 150.09 362 2 10%
Max Throughput-100%Read 16.47 3596 112 4%
RealLife-60%Rand-65%Read 29.68 1882 14 18%
