It is time to say goodbye: This version of Elastic Cloud Enterprise has reached end-of-life (EOL) and is no longer supported.
The documentation for this version is no longer being maintained. If you are running this version, we strongly advise you to upgrade. For the latest information, see the current release documentation.

editECE has specific hardware requirements for memory and storage. We have compiled information for the minimums required to install ECE, recommended minimums, and specific deployment scenarios. The host machines you use must support the x86-64 instruction set.

1 Allocators must be sized to support your Elasticsearch clusters and Kibana instances. We recommend host machines that provide between 128 GB and 256 GB of memory. While smaller hosts might not pack larger Elasticsearch clusters and Kibana instances as efficiently, larger hosts might provide fewer CPU resources per GB of RAM on average. For example, running 64 * 2GB nodes on a 128GB host with 16 vCPUs means that each node will get 2/128 of the total CPU time. This is 1/4 core on average, and might not be sufficient. We recommend inspecting both what is the expcted number and size of the nodes you plan to run on your hosts in order to understand which harware will work best in your environment.
2 For high availability, requires three hosts each of the capacities indicated, spread across three availability zones.
3 For high availability, requires three hosts each of the capacities indicated (except for allocators), spread across three availability zones. For allocators, requires three or more hosts of the capacity indicated, spread across three availability zones.
There are some additional hardware requirements to make sure that Elastic Cloud Enterprise can work as intended, such as the requirement to use fast SSD storage for ECE management services. To learn more, see Choose the Right Host Machines.
The size of your ECE deployment has a bearing on the JVM heap sizes that you should specify during installation. To learn more, see JVM Heap Sizes. For examples, see the deployment scenarios in our Playbook for Production.

Enough storage to support the RAM-to-storage ratio1 |
1 For example, if you use a host with 256 GB of RAM and the default ratio of 1:32, your host must provide 8192 GB of disk space.
