# 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](https://kubernetes.io/releases/) and [OpenShift](https://access.redhat.com/support/policy/updates/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](/docs/latest/operate/rs/databases/memory-performance/eviction-policy/) to `noeviction`. Note that you can't set this using [`rladmin`](/docs/latest/operate/rs/references/cli-utilities/rladmin/), so you must either do it using the admin UI or with the following [REST API](/docs/latest/operate/rs/references/rest-api/) command:
    
    ```bash
    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](/docs/latest/operate/rs/databases/configure/database-persistence/) to AOF - fsync every 1 sec. Note that you can't set this using [`rladmin`](/docs/latest/operate/rs/references/cli-utilities/rladmin/), so you must either do it using the admin UI or with the following [REST API](/docs/latest/operate/rs/references/rest-api/) commands:
    
    ```bash
    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](/docs/latest/integrate/redis-data-integration/faq/#can-i-use-rdi-without-persistence-enabled) 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.
    
    [![Uncluster the RDI database.](/docs/latest/images/rdi/ingest/RDIClusterSetting.webp)](/docs/latest/images/rdi/ingest/RDIClusterSetting.webp)
    
    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:
    
    [![Check that the RDI database is not clustered.](/docs/latest/images/rdi/ingest/RDICheckUnclustered.webp)](/docs/latest/images/rdi/ingest/RDICheckUnclustered.webp)
    
    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.
