实例存储卷
实例存储卷的数量、大小和类型根据实例类型和实例大小决定。某些实例类型（例如，M6、C6 和 R6）不支持实例存储卷，而其他实例类型（例如，M5d、C6gd 和 R6gd）可支持实例存储卷。您向实例附加的实例存储卷不能超过其实例类型所支持的数量。对于支持实例存储卷的实例类型，实例存储卷的数量和大小因实例大小而异。例如，m5d.large 支持 1 x 75 GB 的实例存储卷，而 m5d.24xlarge 支持 4 x 900GB 的实例存储卷。
对于具有 NVMe 实例存储卷的实例类型，所有支持的实例存储卷都会在启动时自动连接到实例。对于具有非 NVMe 实例存储卷的实例类型（例如，C1、C3、M1、M2、M3、R3、D2、H1、I2、G2、X1 和 X1e），您必须在启动时为要连接的实例存储卷手动指定块设备映射。然后，在实例启动后，必须先格式化并装载连接的实例存储卷，然后才能使用它们。无法在启动实例后附加实例存储卷。
某些实例类型使用基于 NVMe 或 SATA 的固态硬盘 (SSD)，而其他实例类型使用基于 SATA 的硬盘驱动器 (HDD)。SSD 提供高随机 I/O 性能，且延迟非常低；但实例终止时不需要保留数据，或者可以利用容错架构。有关更多信息，请参阅SSD 实例存储卷。
NVMe 实例存储卷和某些 HDD 实例存储卷上的数据采用静态加密。有关更多信息，请参阅Amazon EC2 中的数据保护。

使用 AWS CLI 查询实例存储卷信息
您可以使用 describe-instance-types AWS CLI 命令来显示有关实例类型的信息，例如其实例存储卷。以下示例显示了包含实例存储卷的所有 R5 实例的实例存储总大小。
aws ec2 describe-instance-types \ --filters "Name=instance-type,Values=r5*" "Name=instance-storage-supported,Values=true" \ --query "InstanceTypes[].[InstanceType, InstanceStorageInfo.TotalSizeInGB]" \ --output table
输出示例
---------------------------
| DescribeInstanceTypes |
+----------------+--------+
| r5ad.24xlarge | 3600 |
| r5ad.12xlarge | 1800 |
| r5dn.8xlarge | 1200 |
| r5ad.8xlarge | 1200 |
| r5ad.large | 75 |
| r5d.4xlarge | 600 |

| r5d.12xlarge | 1800 |
+----------------+--------+以下示例显示指定实例类型的完整实例存储详细信息。
aws ec2 describe-instance-types \ --filters "Name=instance-type,Values=r5d.4xlarge" \ --query "InstanceTypes[].InstanceStorageInfo"
示例输出显示，此实例类型有两个 300 GB 的 NVMe SSD 卷，总共 600 GB 的实例存储空间。
