Requirements summary

Requirements and recommendations for RDI installations.

The sections below summarize the software and hardware requirements for an RDI installation.

Hardware requirements for VM installation

CPU: A minimum of 4 CPU cores. You should consider adding 2-6 extra cores on top of this if your dataset is big and you want to ingest the baseline snapshot as fast as possible.
RAM: 8GB
Disk: On top of the OS footprint, RDI requires 20GB in the /var folder and 1GB in the /opt folder (to store the log files). This allows space for upgrades.
Network interface: 10GB or more.

OS requirements for VM installation

RHEL 8 or 9
Ubuntu 20.04, 22.04, or 24.04

Kubernetes/OpenShift supported versions

RDI only supports versions of Kubernetes and OpenShift that have not yet reached end-of-life (EOL). See the Kubernetes and OpenShift lifecycle pages for the latest updates.

RDI database requirements

Redis Enterprise v6.4 or greater for the cluster.
For production, 250MB RAM with one primary and one replica is recommended, but for the quickstart or for development, 125MB and a single shard is sufficient.
If you are deploying RDI for a production environment then secure this database with a password and TLS.

Set the database's eviction policy to noeviction. Note that you can't set this using rladmin, so you must either do it using the admin UI or with the following REST API command:

curl -v -k -d '{"eviction_policy": "noeviction"}' \
  -u '<USERNAME>:<PASSWORD>' \
  -H "Content-Type: application/json" \
  -X PUT https://<CLUSTER_FQDN>:9443/v1/bdbs/<BDB_UID>

Set the database's data persistence to AOF - fsync every 1 sec. Note that you can't set this using rladmin, so you must either do it using the admin UI or with the following REST API commands:

curl -v -k -d '{"data_persistence":"aof"}' \
  -u '<USERNAME>:<PASSWORD>' \
  -H "Content-Type: application/json" 
  -X PUT https://<CLUSTER_FQDN>:9443/v1/bdbs/<BDB_UID>
curl -v -k -d '{"aof_policy":"appendfsync-every-sec"}' \
  -u '<USERNAME>:<PASSWORD>' \
  -H "Content-Type: application/json" \
  -X PUT https://<CLUSTER_FQDN>:9443/v1/bdbs/<BDB_UID>

If you don't have permissions to use AOF persistence, please check the Using RDI without persistence section in the FAQ.

Ensure that the RDI database is not clustered. RDI will not work correctly if the RDI database is clustered (but note that the target database can be clustered without any problems).

If the Database clustering option is checked when you create the RDI database (as shown below), you must uncheck it before proceeding.

You can check if your RDI database is clustered from its Configuration tab in the Redis Enterprise console. The Database clustering option should be set to None, as shown in the following screenshot:

If you find the database has been clustered by mistake, you must create a new database with clustering disabled before continuing with the RDI installation.
