# 查找 EBS 优化的 EC2 实例类型
<a name="describe-ebs-optimization"></a>

您可以查看每个区域中支持 EBS 优化的实例类型。

------
#### [ Console ]

**查找默认进行 EBS 优化的实例类型**

1. 通过以下网址打开 Amazon EC2 控制台：[https://console.aws.amazon.com/ec2/](https://console.amazonaws.cn/ec2/)。

1. 在导航窗格中，选择 **Instance Types (实例类型)**。

1. 添加筛选条件 **EBS 优化支持 = default**。

1. （可选）选择**首选项**图标，然后启用相关列，例如 **EBS 最大 IOPS** 和 **EBS 基准 IOPS**。

1. （可选）添加筛选条件以进一步筛选相关的特定实例类型。

#### [ Amazon CLI ]

**查找默认进行 EBS 优化的实例类型**  
使用以下 [describe-instance-types](https://docs.amazonaws.cn/cli/latest/reference/ec2/describe-instance-types.html) 命令。

```
aws ec2 describe-instance-types \
--filters Name=ebs-info.ebs-optimized-support,Values=default  \
--query 'InstanceTypes[].{InstanceType:InstanceType, "MaxBandwidth(Mb/s)":EbsInfo.EbsOptimizedInfo.MaximumBandwidthInMbps, MaxIOPS:EbsInfo.EbsOptimizedInfo.MaximumIops, "MaxThroughput(MB/s)":EbsInfo.EbsOptimizedInfo.MaximumThroughputInMBps}' \
--output=table
```

**查找可选支持 EBS 优化的实例类型**  
使用以下 [describe-instance-types](https://docs.amazonaws.cn/cli/latest/reference/ec2/describe-instance-types.html) 命令。

```
aws ec2 describe-instance-types \
--filters Name=ebs-info.ebs-optimized-support,Values=supported \
--query 'InstanceTypes[].{InstanceType:InstanceType, "MaxBandwidth(Mb/s)":EbsInfo.EbsOptimizedInfo.MaximumBandwidthInMbps, MaxIOPS:EbsInfo.EbsOptimizedInfo.MaximumIops, "MaxThroughput(MB/s)":EbsInfo.EbsOptimizedInfo.MaximumThroughputInMBps}' \
--output=table
```

#### [ PowerShell ]

**查找默认进行 EBS 优化的实例类型**  
使用 [Get-EC2InstanceType](https://docs.amazonaws.cn/powershell/latest/reference/items/Get-EC2InstanceType.html) cmdlet。

```
Get-EC2InstanceType `
    -Filter @{Name="ebs-info.ebs-optimized-support"; Values="default"} | `
    Select InstanceType, `
        @{Name="MaxBandwidth(Mb/s)"; Expression={($_.EbsInfo.EbsOptimizedInfo.MaximumBandwidthInMbps)}}, `
        @{Name="MaxIOPS"; Expression={($_.EbsInfo.EbsOptimizedInfo.MaximumIops)}}, `
        @{Name="MaxThroughput (MB/s)"; Expression={($_.EbsInfo.EbsOptimizedInfo.MaximumThroughputInMBps)}}
```

**查找可选支持 EBS 优化的实例类型**  
使用 [Get-EC2InstanceType](https://docs.amazonaws.cn/powershell/latest/reference/items/Get-EC2InstanceType.html) cmdlet。

```
Get-EC2InstanceType `
    -Filter @{Name="ebs-info.ebs-optimized-support"; Values="supported"} | `
    Select InstanceType, `
        @{Name="MaxBandwidth(Mb/s)"; Expression={($_.EbsInfo.EbsOptimizedInfo.MaximumBandwidthInMbps)}}, `
        @{Name="MaxIOPS"; Expression={($_.EbsInfo.EbsOptimizedInfo.MaximumIops)}}, `
        @{Name="MaxThroughput (MB/s)"; Expression={($_.EbsInfo.EbsOptimizedInfo.MaximumThroughputInMBps)}}
```

下面是 `eu-west-1` 的示例输出。
