# Amazon EMR 支持的实例类型
<a name="emr-supported-instance-types"></a>

本节介绍 Amazon EMR 支持的实例类型（按 AWS 区域整理）。要了解有关实例类型的更多信息，请参阅 [Amazon EC2 实例](https://aws.amazon.com/ec2/instance-types/)和 [Amazon Linux AMI 实例类型矩阵](https://aws.amazon.com/amazon-linux-ami/instance-type-matrix/)。

并非所有实例类型在所有区域内都可用，实例可用性取决于指定区域和可用区的可用性和需求。实例的可用区由您用于启动集群的子网决定。

## 注意事项
<a name="emr-supported-instance-types-considerations"></a>

为 Amazon EMR 集群选择实例类型时，请考虑以下事项。

**重要**  
当您使用选择实例类型时 AWS 管理控制台，显示的每种实例类型**的 vCPU** 数量是该**实例类型**的 YARN vcore 数，而不是该实例类型的 EC2 v CPUs 数。有关每种实例类型的 v CPUs 数的更多信息，请参阅 [Amazon EC2 实例类型](https://aws.amazon.com/ec2/instance-types/)。
+ 如果您使用在指定区域和可用区中不可用的实例类型创建集群，则您的集群可能无法预置或可能预置失败。有关实例可用性的信息，请参阅 [Amazon EMR 定价页面](https://aws.amazon.com/emr/pricing)或者查看此页面上的 [支持的实例类型由 AWS 区域](#emr-instance-types-by-region) 表格。
+ 从 Amazon EMR 5.13.0 版本开始，所有实例均为根卷使用 HVM 虚拟化和 EBS 支持的存储。采用 5.13.0 之前的 Amazon EMR 发行版时，有些上一代实例使用 PVM 虚拟化。有关更多信息，请参阅 [Linux AMI 虚拟化类型](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/virtualization_types.html)。
+ 由于缺乏硬件支持和默认设置，可能会导致内存和核心利用率不足，因此如果运行低于 5.36.1 和 6.10.0 的 Amazon EMR 发行版，我们不建议使用 `c7a`、`c7i`、`m7i`、`m7i-flex`、`r7a`、`r7i`、`r7iz`、`i4i.12xlarge`、`i4i.24xlarge` 等实例类型。如果在这些发行版中运行上述实例类型，可能会降低性能，也不会看到新实例类型的预期优势，比如 `c7i` 和 `c6i`。要在这些性能类型下实现最佳资源利用率和性能，应运行 5.36.1 及更高版本或 6.10.0 及更高版本，以最大限度发挥其功能。
+ 一些实例类型支持增强联网。有关更多信息，请参阅[有关 Linux 的增强联网](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.html)。
+ NVIDIA 和 CUDA 驱动程序默认安装在 GPU 实例类型上。
