IOPS问题 [英] IOPS question

问题描述

当我选择虚拟机大小时，存在"最大IOPS"。

When I am choosing a VM size, there is a 'max IOPS'.

我对此非常困惑，因为我们可以附加IOPS较高的磁盘。 ..

I'm pretty confused on this because we can attach disks with a higher IOPS...

我不明白。

推荐答案

嗨史蒂文，

让我们举一个
Standard_D2s_v3 Vm。它的IOPS限制为3200，吞吐量限制为48 MBps。

Lets take an example of Standard_D2s_v3 Vm. It has the IOPS limit of 3200 and throughput limit of 48 MBps.

我们可以将具有更多iops和吞吐量的磁盘附加到该VM。

We can attach a disk with more iops and throughput also to that VM.

但是VM不能每秒写入超过48 MB的磁盘，尽管磁盘支持更多。

But the VM cant write more than 48 MB per second to the disk though the disk supports more.

随着磁盘的IOPS和吞吐量增加，我们将支付更多费用。所以我们需要在VM的IOPS和吞吐量以及磁盘的IOPS和吞吐量之间找到平衡。

With more IOPS and Throughput for the disks, We will be paying more. So we need to find a balance between the VM's IOPS and Throughput and the disk 's IOPS and throughput.

如果我们选择
标准SSD 磁盘，E10可能是一个不错的选择。虽然该磁盘的IOPS较少，但 吞吐量匹配。   如果我们有两个或更多磁盘连接到VM，那么我们可以总结所有磁盘的IOPS和吞吐量。从VM上运行
的应用程序中我们还需要制作 确保我们从两个磁盘读取和写入数据。

If we pick standard SSD disk for this VM, E10 can be a good option. Though that disk has less IOPS,  throughput matches.   If we have two or more disks attached to a VM, Then we can sum the IOPS and throughput of all disks. From the application which is running on the VM's also we need to make  sure that we read and write data from both the disks.

应用程序类型决定我们需要的天气与VM的IOPS匹配到磁盘IOPS是否正在增加。

The type of application decides weather we need match the IOPS of the VM to Disks IOPS are thropughput.

例如，Web应用程序将需要更多IOPS。 浏览
