vRealize Log Insight supports various deployment architectures to meet scalability and high availability requirements. A six-node cluster with three nodes in each of two datacenters is a valid deployment model, offering both redundancy and load balancing across datacenters.
Key Considerations:
* Cluster Composition:
* A vRealize Log Insight cluster can include up to 12 nodes: one primary and multiple worker nodes.
* Nodes within a cluster should be of the same size and located within the same data center to ensure optimal performance.
* Integrated Load Balancer (ILB):
* Utilizing the ILB ensures that incoming ingestion traffic is properly balanced across nodes, maintaining availability even if some nodes become unavailable.
* Data Center Placement:
* While nodes are typically deployed within the same data center, deploying across multiple data centers can provide disaster recovery capabilities.
* Ensure that network latency between datacenters is minimal to prevent performance degradation.
