Recommendations For Leap And Supported Service-level Agreements (SLAS)


Userlevel 3
Badge +2

Nutanix recommends the following best practices for implementing disaster recovery using Leap. Along with these recommendations, there are specific recommendations for data protection with Synchronous replication (0 RPO).

For data protection with Synchronous replication recommendations, see Recommendations for Synchronous Replication.

General Recommendations

  • Create all Leap entities (protection policies, recovery plans, and VM categories) at the primary site, where the VMs exist.

  • Upgrade the Prism Central before upgrading the Prism Element running on the clusters registered to Prism Central.

  • Disable Synchronous replication before unpairing the sites.
    If you unpair the sites while the guest VMs in the Nutanix clusters are still in synchronization, the Nutanix cluster becomes unstable. For more information about disabling Synchronous replication, see Disabling the Synchronous Replication (from 5.12 to 5.17 only).

Recommendation for Virtual Networks

Do not create virtual networks that have the same name or overlapping IP address ranges.

Recommendation for Container Mapping

Create storage containers with the same name on both the primary and recovery Nutanix clusters.

Leap automatically maps the storage containers during the first replication (seeding) of a guest VM. If a storage container with the same name exists on both the primary and recovery Nutanix clusters, the recovery points replicate to the same name storage container only. For example, if your protected guest VMs are in the SelfServiceContainer on the primary Nutanix cluster, and the recovery Nutanix cluster also has SelfServiceContainer, the recovery points replicate to SelfServiceContainer only. If a storage container with the same name does not exist at the recovery site, the recovery points replicate to a random storage container at the recovery site. For more information about creating storage containers on the Nutanix clusters, see CREATING A STORAGE CONTAINER in PRISM WEB CONSOLE GUIDE.

Recommendation for Migrating from Protection Domains to Protection Policies

While migrating VMs from protection domains to protection policies, do not delete the VM snapshots in the protection domain. Nutanix recommends keeping the VM snapshots in the protection domain until the first recovery point for the VMs is available on the Prism Central. For more information, see Migrating VMs from a Protection Domain to a Protection Policy.

You can configure disaster recovery using Leap between two AHV or ESXi clusters in different availability zones or the same availability zone.

For more information about configuring disaster recovery with Leap between two clusters in the different availability zones, see Leap with Two Prism Centrals. Leap with two Prism Centrals protect VMs and replicates the data in the following three schedules.

For more information about configuring disaster recovery using Leap between two clusters in the same availability zone, see Leap with Single Prism Central. Leap with single Prism Central protects VMs and replicates the data in the following two schedules.
