# Amazon OpenSearch Service 配額
AWS 您的帳戶具有每個 AWS 服務的預設配額，先前稱為限制。除非另有說明，否則每個配額都是區域特定的。
若要檢視 OpenSearch Service 網域和執行個體、Amazon OpenSearch Serverless 和 Amazon OpenSearch Ingestion 的配額，請參閱 中的 [Amazon OpenSearch Service 配額](https://docs.aws.amazon.com/general/latest/gr/opensearch-service.html#opensearch-limits)*AWS 一般參考*。
若要在 中檢視 OpenSearch Service 的配額 AWS 管理主控台，請開啟 [Service Quotas 主控台](https://console.aws.amazon.com/servicequotas/home)。在導覽窗格中，選擇 **AWS 服務**，然後選取 **Amazon OpenSearch Service**。若要請求提高配額，請參閱[《Service Quotas 使用者指南》](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html)中的*請求提高配額*。
## 暖節點儲存配額
下表列出暖節點執行個體類型，以及每種類型可以使用的儲存容量上限。對於 OpenSearch Optimized OI2 執行個體，80% 的本機儲存體可供快取使用，且最大可定址暖儲存體是快取儲存體大小的 5 倍。
例如，如果 OI2 執行個體具有 468 GB 的本機儲存體：
+ 快取儲存 = 375 GB (80% 的本機儲存）
+ 最大可定址暖儲存 = 1875 GB (5 x 375 GB 快取）
| 執行個體類型 | 執行個體儲存 (GB) | 快取大小 (GB) | 最大可定址暖儲存 (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 儲存配額
下表列出 UltraWarm 執行個體類型，以及每個類型可使用的儲存量上限。如需 UltraWarm 的詳細資訊，請參閱[Amazon OpenSearch Service 的 UltraWarm 儲存](ultrawarm.md)。
| 執行個體類型 | 最大儲存空間 |
| --- | --- |
| ultrawarm1.medium.search | 1.5 TiB |
| ultrawarm1.large.search | 20 TiB |
## 每個 AZ 的資料節點數量
下表列出 AZ 部署的資料節點總數低於 ，整體限制表示每個限制的資料節點數量，包括熱節點和暖節點計數。每種類型都可以使用的儲存體。
| AZ 組態 | 熱節點計數限制 | 暖節點計數限制 | 整體限制 （熱 \$1 暖） |
| --- | --- | --- | --- |
| 1 - AZ | 334 | 250 | 334 |

## EBS 磁碟區大小配額
下表顯示 OpenSearch Service 支援的每個執行個體類型的 EBS 磁碟區大小下限和上限。如需執行個體類型及包含執行個體儲存體和額外硬體詳細資訊的資訊，請參閱 [Amazon OpenSearch Service 定價](https://aws.amazon.com/elasticsearch-service/pricing/)。
+ 如果您在建立網域時在 **EBS 磁碟區類型**下選擇磁性儲存，除了 t2.small 和 t2.medium 以外的所有執行個體類型，以及不支援磁性儲存的所有 Graviton 執行個體 (M6g、C6g, R6g 和 R6gd) 的磁碟區大小上限為 100 GiB。對於下表中列出的最大大小，請選擇其中一個 SSD 選項。
+ 有些更早產生的執行個體類型包括執行個體儲存體，也支援 EBS 儲存。如果您選擇其中一種 EBS 執行個體類型、磁碟區儲存空間 *不會* 累加。您可以使用 EBS 磁碟區或執行個體儲存體，但不能兩者共用。
+ 對於 EBS gp3 磁碟區，支援的最大限制為 80，000 IOPS 和 2，000 MB/s 輸送量。請注意，視您的執行個體類型而定，網域的有效限制可能會較低。如需特定執行個體的最大限制，請參閱[執行個體類型限制](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-optimized.html#current-general-purpose)。
