你好!

在读的时候存储QoS的文档提到以下是一个限制:

存储QoS不支持Metro可用性,同步复制和AFS虚拟机。

如果我将存储QoS应用于VM,我的实际结果将是什么同步复制的?我什至可以这样做吗?或反之亦然,如果我开始使用存储QoS复制VM,会发生什么?

存储QoS与Metro功能冲突如何?

谢谢。

嗨,马丁,

这是个有趣的问题。
我最初的想法是QoS增加了群集延迟。由于数据写入的提交发生在两个站点上,因此后者对于Metro的可用性至关重要。在这种情况下,延迟增加可能会对MA产生负面影响。

挖掘更深入的挖掘,事实证明,至少是当前功能实现的方式,QoS是由ESXI插入的。

谢谢回复。

在这种情况下,我们计划使用AHV,但我忘了在我的OP中提到这一点。

尽管如此,存储QoS的使用受到限制,因此这不应该是问题,我只是想更多地了解限制 - 在这方面,官方文档需要大大扩展。
