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 per cluster |
40 (except for the T2 and T3 instance types, which have a maximum of 10) To request an increase up to 200 data nodes (for Elasticsearch 2.3
or later), create a case with the AWS Support
Center |
Maximum number of warm nodes per cluster |
150 |
Maximum total number of data and warm nodes per cluster |
200 You might have to request a data node limit increase to reach this total. For example, your domain might have 80 data nodes and 120 warm nodes. |
Maximum number of dedicated master nodes per cluster |
5 You can use the T2 and T3 instance types for dedicated master
nodes only if the number of data nodes is 10 or fewer. We don't
recommend T2 or |
Maximum total storage per cluster |
3 PiB This maximum is the sum of all data nodes and warm nodes. For
example, your domain might have 36
|
Smallest supported instance type per Elasticsearch version |
|
Maximum number of domains per account (per Region) |
100 |
Maximum number of custom packages per account (per Region) |
25 |
Maximum number of custom packages per domain |
20 |

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.
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
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.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 for 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.
