Amazon EC2 实例存储
实例存储 为您的实例提供临时性块级存储。此存储位于已物理附加到主机的磁盘上。实例存储非常适合临时存储频繁更改的信息，例如缓冲区、缓存、Scratch 数据和其他临时内容。它还可用于存储您在一组实例中复制的临时数据，例如负载均衡的 Web 服务器池。
实例存储由一个或多个显示为块储存设备的实例存储卷组成。实例存储的大小以及可用设备的数量因实例类型而异。
实例存储卷的虚拟设备为 ephemeral[0-23]。支持一个实例存储卷的实例类型具有 ephemeral0。支持两个实例存储卷的实例类型有 ephemeral0 和 ephemeral1 等。
实例存储生命周期
您只能在启动实例时指定实例的实例存储卷。您无法将实例存储卷与一个实例分离并将该卷附加到另一个实例。
实例存储内的数据仅在与关联的实例的生命周期内保留。如果实例重启 (无论是故意还是意外)，实例存储内的数据都会保留下来。然而，在以下任一情况下，实例存储中的数据会丢失：
-
底层磁盘驱动器发生故障
-
实例停止
-
实例休眠
-
实例终止
因此，切勿依赖实例存储来存储珍贵且需要长期保存的数据。应使用更持久的数据存储，如 Amazon S3、Amazon EBS 或 Amazon EFS。
当您停止、休眠或终止某个实例时，实例存储中的每个存储块都会被重置。因此，无法通过另一实例的实例存储访问您的数据。
如果您从实例创建 AMI，则从此 AMI 中启动实例时，实例存储卷上的数据不能保存且不会出现在实例存储卷上。
如果更改实例类型，实例存储不会附加到新实例类型。有关更多信息，请参阅更改实例类型。
实例存储卷
实例类型决定了可用的实例存储的大小以及用于实例存储卷的硬件类型。实例存储卷包含在实例使用成本中。您必须指定在启动实例时要使用的实例存储卷 (NVMe 实例存储卷除外，因为它们在默认情况下可用)。之后设置实例存储卷的格式并挂载这些卷，然后再使用这些卷。您无法在启动实例后使实例存储卷可用。有关更多信息，请参阅将实例存储卷添加到您的 EC2 实例。
某些实例类型使用基于 NVMe 或 SATA 的固态硬盘 (SSD) 来提供高随机 I/O 性能。如果您需要延迟非常低的存储，且实例终止时不需要保留数据或可以使用容错架构，则可以选择这种实例。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。

* 如果附加到特定实例的卷没有初始化，将会进行初始写入。有关更多信息，请参阅 优化实例存储卷的磁盘性能。
** 有关更多信息，请参阅 实例存储卷 TRIM 支持。
† c1.medium 和 m1.small 实例类型还包括一个不会在启动时自动启用的 900MB 实例存储交换卷。有关更多信息，请参阅实例存储交换卷。
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 |
. . .
| r5dn.2xlarge | 300 |
| 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。
