亚马逊 OpenSearch 服务配额
您的 AWS 账户对每项 AWS 服务都有默认配额（以前称为限制）。除非另有说明，否则每个配额都是 Region-specific。
要查看 OpenSearch 服务域和实例、Amazon OpenSearch Serverl OpenSearch ess 和 Amazon Ingestion 的配额，请参阅中的亚马逊 OpenSearch 服务配额。AWS 一般参考
要在中查看 OpenSearch 服务配额 AWS 管理控制台，请打开 Serv ice Quotas 控制台
注意
如果您在 VPC 域上启用通过 VPC 的出口，请在每个选定的子网中为 OpenSearch 服务在您的 VPC 中创建的出口网络接口保留其他 IP 地址。有关更多信息，请参阅 限制和注意事项。
温节点存储配额
下表列出了温节点实例类型以及每种类型可以使用的最大存储量。对于 OpenSearch 优化的 OI2 实例，80% 的本地存储空间可用作缓存，最大可寻址的温存储空间是缓存存储空间大小的 5 倍。
例如，如果 OI2 实例有 468 GB 的本地存储空间：
缓存存储空间 = 375 GB（占本地存储空间的 80%）
最大可寻址热存储空间 = 1875 GB（5 x 375 GB 缓存）
| 实例类型 | 实例存储 (GB) | 缓存大小 (GB) | 最大可寻址热存储空间 (GB) |
|---|---|---|---|
| oi2.large.search | 468 | 375 | 1875 |
| oi2.xlarge.search | 937 | 750 | 3750 |
| oi2.2xlarge.search | 1875 | 1500 | 7500 |
| oi2.4xlarge.search | 3750 | 3000 | 15000 |
| oi2.8xlarge.search | 7500 | 6000 | 30000 |
UltraWarm 存储配额
下表列出了 UltraWarm 实例类型和每种类型可以使用的最大存储量。有关的更多信息 UltraWarm，请参阅UltraWarm 亚马逊 OpenSearch 服务的存储空间。
| 实例类型 | 最大存储空间 |
|---|---|
| ultrawarm1.medium.search | 1.5 TiB |
| ultrawarm1.large.search | 20 TiB |
每个可用区的数据节点数
下表列出可用区部署的数据节点总数，总限制表示每个限制的数据节点数量，包括热节点和温节点数量。每种类型可使用的存储空间。
| 可用区配置 | 热节点计数限制 | 温节点计数限制 | 总极限（热 + 温） |
|---|---|---|---|
| 1 - 可用区 | 334 | 250 | 334 |
| 2 - 可用区 | 668 | 500 | 668 |
| 3 - 可用区 | 1002 | 750 | 1002 |

EBS 卷大小配额
下表显示了 OpenSearch 服务支持的每种实例类型的 EBS 卷的最小和最大大小。有关哪些实例类型包括实例存储和其他硬件详情的信息，请参阅 Amazon S OpenSearch ervice 定价
-
如果您在创建域时选择 EBS 卷类型下的磁性存储，除 t2.small 和 t2.medium 之外的所有实例类型以及所有不支持磁性存储的引力实例（M6g、C6g、R6g 和 R6gd）的最大卷大小为 100 GiB。对于下表中列出的最大大小，选择 SSD 选项之一。
-
一些较旧版本的实例类型包含实例存储，但也支持 EBS 存储。如果您为这些实例类型之一选择了 EBS 存储，则不会 添加存储卷。您可以使用 EBS 卷或实例存储，但不能同时使用二者。
-
对于 EBS gp3 卷，支持的最大限制为 80,000 IOPS 和 2,000 吞吐量。 MB/s 请注意，您的域名的有效限制可能会更低，具体取决于您的实例类型。有关特定于实例的最大限制，请参阅实例类型限制。
