比较簇之间的X射线结果

大家好，

经过一些建议。我对2 x相同的所有闪光簇运行了默认的“四个角” Microbenchmark”，并且我的结果非常不同，因此不确定为什么。

平均随机读取IOPS差异约为60k，随机写入IOPS约为10k。我知道在两个群集上运行测试都无法提供确切的匹配，但是这些结果看起来很不一样。请注意，这两个都是2节点簇，两者在规范中都是相同的，因此不确定这是否重要。

我在2 x相同的6节点混合阵列上也得到了相同的功能，随机读取IOPS不同于200k，随机写入IOPS以40k为单位！

使用测试本身中的默认设置，在所有簇上使用相同的X射线设备。

在对这些查询的可能解释之后，如果有人如此有帮助。

非常感谢。

Hi All,<\/p>

Just after some advice.\u00a0 I\u2019ve run the default \u2018Four Corners Microbenchmark\u2019 against 2 x identical All Flash clusters and I get very different results and not sure why.<\/p>

The average random read IOPS differ by around 60k, and the random write IOPS around 10k. I know running the test on both clusters will not provide an exact match, but these results appear very different.\u00a0 Please note these are both 2-node clusters, both are identical in specification so not sure if this matters.<\/p>

I also get the same on 2 x identical 6-node Hybrid arrays, random\u00a0read IOPS differ by 200k and random write IOPS by 40k!<\/p>

The same X-Ray appliance was used on all clusters, using the default settings in the test itself.<\/p>

Just after a possible explanation to these queries, if somebody could be so helpful.<\/p>

Thanks very much.<\/p>","quoteUsername":"Mark-M","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
