根据IOPS为VM查找匹配的磁盘 [英] Finding a matching disk for a VM based on IOPS

问题描述

您好，

我决定在Azure上购买虚拟机。我现在需要找到一个可以根据IOPS与该VM一起使用的磁盘。我该如何做？

I have decided on a VM to buy on Azure. I now need to find a disk which can go along with that VM based on IOPS. How do I do the same?

为磁盘找到的IOPS数据以不同的单位提及，而针对VM提到的IOPS数据则以不同的单位表示。

The IOPS data found for the disks is mentioned in different units and that mentioned for a VM are in a different units.

我们通常如何做出这个决定。关键是要找出VM或磁盘是否是彼此的瓶颈。

How do we usually make this decision. The key is to find whether the VM or the disk is being a bottleneck for each other.

问候，

推荐答案

HI，

让我们看一下VM" Standard_D2s_v3 "和

标准SSD 磁盘。

Lets take a look at the the VM "Standard_D2s_v3" and standard SSD disks.

vm支持最高3200 IOPS /  48 MBps。标准ssd磁盘中最接近的匹配是E6，其具有240 IOPS / 50 MIB（52.5 MB）。受吞吐量限制。如果您的应用程序使用较少的吞吐量和较高的IOPS，那么您可以获得更高的数字（如
E10）。网络应用程序（如在线购物）需要较高的IOPS，但可以通过较少的吞吐量来维持。   您的应用程序仅决定IOPS和吞吐量之间的平衡。

That vm supports upto 3200 IOPS /  48 MBps. The closest match in the standard ssd Disk is E6 which has 240 IOPS / 50 MIB (52.5 MB). Limited by throughput here. If your application uses less throughput and high IOPS, Then you can go for higher numbers(Like E10). Web apps(like online shopping) will need high IOPS but can sustain with less Throughput.   Your Application only decides the balance between IOPS and throughput.

从Mib转换为MB可能有点烦人。但差别很小。

Converting from Mib to MB might be little annoying. But the difference is small.

我要求你完成这个
文档，讨论IOPS，吞吐量，应用程序性能等 

I request you to go through this document which discusses about IOPS, Throughput, application Performance etc 

您还可以添加多个磁盘到VM并共享该VM的IOPS和吞吐量。

You can also add Multiple disks to the VM and share the IOPS and throughput of that VM.
