Best Practices for Partitioning Nutanix Clusters to Ensure High Availability and Prevent Cluster Splitting.

In a distributed and resilient infrastructure, ensuring high availability and eliminating the risk of data loss are paramount considerations. When dealing with multiple physical sites or availability zones, it becomes essential to design the Nutanix clusters in a way that guarantees fault tolerance and prevents the possibility of cluster partitioning. By following recommended best practices, such as creating separate Nutanix clusters per availability zone and utilizing appropriate connectivity tools, organizations can achieve robust data and application availability while safeguarding against potential split-brain scenarios.

Leaf-Spine

The leaf-spine network architecture has gained popularity in recent datacenter installations due to its simplicity of deployment and scalability. In this design, a minimum of two spine switches and two leaf switches are required. Each leaf switch is connected to every spine switch through uplink ports. Unlike traditional leaf-spine designs, there are no direct connections between the spine switches or between the leaf switches.

To minimize uplink oversubscription, it is advisable to employ higher-speed uplinks compared to the edge ports. If additional uplink capacity is required, spine switches or uplink ports can be easily added to the network.

For expanding the leaf-spine network, the inclusion of additional leaf and spine switches is necessary. The advantage of this design is that it allows Nutanix clusters to seamlessly extend across multiple racks while maintaining connectivity to the same switch fabric, as the maximum number of switch hops between any two Nutanix nodes does not exceed three.

Core-Aggregation-Access

The three-tier (or core-aggregation-access) design is a modular arrangement that provides the flexibility to upgrade and scale individual layers independently. It is essential to ensure that all nodes within a Nutanix cluster are connected to the same aggregation layer to adhere to the three-switch-hop guideline.

Expanding the three-tier network design might involve incorporating an additional aggregation and access layer into the core. Consequently, there may be an increase in the number of switch hops between the two access layers, exceeding the recommended limit of three. To maintain adherence to the guideline, it is advisable to allocate Nutanix nodes to separate aggregation and access layers, effectively separating them into distinct clusters. In the provided example, Cluster 1 connects to one aggregation layer, while Cluster 2 connects to a different aggregation layer.

Various methods exist for interconnecting switches within the three-tier design, resulting in potential variations in your deployment compared to the illustrated example.

Multisite Designs

In scenarios where multiple physical sites or availability zones are present, it is not recommended to have a single Nutanix cluster spanning across them. Instead, the preferred approach is to establish multiple Nutanix clusters, with each cluster assigned to a specific availability zone. These clusters can be interconnected using tools such as asynchronous disaster recovery, NearSync, and Metro Availability. By adopting this design, data and applications can achieve high availability while mitigating the risk of a split-brain scenario, where a Nutanix cluster becomes partitioned due to loss of connectivity between the two sites.
