Amazon OpenSearch Service quotas
Your AWS account has default quotas, formerly referred to as limits, for each AWS service. Unless otherwise noted, each quota is Region-specific.
To view the quotas for OpenSearch Service domains and instances, Amazon OpenSearch Serverless, and Amazon OpenSearch Ingestion, see Amazon OpenSearch Service quotas in the AWS General Reference.
To view the quotas for OpenSearch Service in the AWS Management Console, open the Service Quotas console
UltraWarm storage quotas
The following table lists the UltraWarm instance types and the maximum amount of storage that each type can use. For more information about UltraWarm, see UltraWarm storage for Amazon OpenSearch Service.
| Instance type | Maximum storage |
|---|---|
| ultrawarm1.medium.search | 1.5 TiB |
| ultrawarm1.large.search | 20 TiB |
Number of data nodes per AZ
The following table lists the total number of data nodes for AZ deployment is below, the overall limit signifies the number of data nodes per limit including both the hot and warm node count. storage that each type can use.
| AZ Configuration | Hot Node Count Limit | Warm Node Count Limit | Overall Limit (Hot + Warm) |
|---|---|---|---|
| 1 - AZ | 334 | 250 | 334 |
| 2 - AZ | 668 | 500 | 668 |
| 3 - AZ | 1002 | 750 | 1002 |
Total node limit by instance family
The following table lists the total node limit by instance family.
| Instance family | ElasticSearch OpenSearch up to 2.15 | OpenSearch 2.17 and above | Default limit |
|---|---|---|---|
| T2 | 10 | 10 | 10 |

EBS volume size quotas
The following table shows the minimum and maximum sizes for EBS volumes for each
instance type that OpenSearch Service supports. For information about which instance types include
instance storage and additional hardware details, see Amazon OpenSearch Service
pricing
-
If you choose magnetic storage under EBS volume type when creating your domain, the maximum volume size is 100 GiB for all instance types except t2.small and t2.medium, and all Graviton instances (M6g, C6g, R6g, and R6gd), which don't support magnetic storage. For the maximum sizes listed in the following table, choose one of the SSD options.
-
Some older-generation instance types include instance storage, but also support EBS storage. If you choose EBS storage for one of these instance types, the storage volumes are not additive. You can use either an EBS volume or the instance storage, not both.
| Instance type | Minimum EBS size | Maximum EBS size (gp2) | Maximum EBS size (gp3) |
