Chapter 11. Post-deployment configuration suggestions

Depending on your requirements, you may want to perform some additional configuration on your newly deployed Red Hat Hyperconverged Infrastructure. This section contains suggested next steps for additional configuration.

Details on these processes are available in Maintaining Red Hat Hyperconverged Infrastructure.

11.1. Configure a logical volume cache for improved performance

If your main storage devices are not Solid State Disks (SSDs), Red Hat recommends configuring a logical volume cache (lvmcache) to achieve the required performance for Red Hat Hyperconverged Infrastructure deployments.

See Configuring a logical volume cache for improved performance for details.

11.2. Configure fencing for high availability

Fencing allows a cluster to enforce performance and availability policies and react to unexpected host failures by automatically rebooting virtualization hosts.

See Configure High Availability using fencing policies for further information.

11.3. Configure geo-replication for disaster recovery

Geo-replication is used to synchronize data from one Red Hat Gluster Storage cluster to another. Synchronizing the local data volume from your discrete Red Hat Hyperconverged Infrastructure (RHHI) cluster to a central data center on a regular basis helps ensure you can restore your cluster to a working state after an outage.

See Configuring geo-replication for disaster recovery for details.
