Amazon Elasticsearch Service Limits
The following tables show limits for Amazon ES resources, including the number of nodes per cluster, the minimum and maximum sizes for EBS volumes, and network limits.
Cluster and Instance Limits
The following table shows Amazon ES limits for clusters and instances.
| Clusters and Instances | Limit |
|---|---|
|
Maximum number of data nodes (including warm nodes) per cluster |
40 (except for the T2 instance types, which have a maximum of 10) The default limit is 40 data nodes per cluster. To request an
increase up to 200 (for Elasticsearch 2.3 or later), create a
case with the AWS Support Center For more information about requesting an increase, see AWS Service Limits. |
|
Maximum number of warm nodes per cluster |
45 |
|
Maximum number of dedicated master nodes |
5 You can use the T2 instance types for dedicated master nodes (not recommended for production domains) only if the number of data nodes is 10 or fewer. |
|
Smallest supported instance type |
|
|
Maximum number of domains per account (per Region) |
100 |
For a list of the instance types that Amazon ES supports, see Supported Instance Types.
UltraWarm Storage Limits
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 for Amazon Elasticsearch Service (Preview).
| Instance Type | Maximum Storage |
|---|---|
ultrawarm1.medium.elasticsearch |
1.5 TiB |
ultrawarm1.large.elasticsearch |
20 TiB |
EBS Volume Size Limits
The following table shows the minimum and maximum sizes for EBS volumes for each
instance type that Amazon ES supports.
For
information about which instance types include instance storage and additional hardware
details, see Amazon Elasticsearch Service

-
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.micro,t2.small, andt2.medium. For the maximum sizes listed in the following table, choose one of the SSD options. -
512 GiB is the maximum volume size that is supported with Elasticsearch version 1.5.
-
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.
