The analytics cluster of the vRealize Operations Manager deployment contains the nodes that analyze and store data from the monitored components. You deploy a configuration of the analytics cluster that satisfies the requirements for monitoring the number of virtual machines in the design objectives of this validated design.

Deploy a 3-node vRealize Operations Manager analytics cluster in the cross-region application virtual network. The analytics cluster consists of one master node, one master replica node, and one data node to enable scale out and high availability.

Design Decision

Design Justification

Design Implication

SDDC-OPS-MON-001

Deploy vRealize Operations Manager as a cluster of three nodes: one master, one master replica, and one data node. Use this deployment to monitor Region A and Region B.

  • Provides the initial scale capacity required for monitoring up to 1,000 VMs.

  • Supports scale-up with more data nodes.

  • You must size identically all appliances which increases the resources requirements in the SDDC.

  • You must manually install the additional data nodes as per the data node scale guidelines.

SDDC-OPS-MON-002

Deploy two remote collector nodes per region.

Removes the load from the analytics cluster from collecting metrics from applications that do not fail over between regions.

You must assign a collector group when configuring the monitoring of a solution.

SDDC-OPS-MON-003

Apply vSphere Distributed Resource Scheduler (DRS) anti-affinity rules to the vRealize Operations Manager analytics cluster.

Using vSphere DRS prevents the vRealize Operations Manager analytics cluster nodes from running on the same ESXi host and risking the high availability of the cluster.

  • You must perform additional configuration to set up an anti-affinity rule.

  • You can put in maintenance mode only a single ESXi host at a time in a management cluster of four ESXi hosts.

SDDC-OPS-MON-004

Apply vSphere Distributed Resource Scheduler (DRS) anti-affinity rules to the vRealize Operations Manager remote collector group.

Using vSphere DRS prevents the vRealize Operations Manager remote collector nodes from running on the same ESXi host and risking the high availability of the cluster.

  • You must perform additional configuration to set up an anti-affinity rule.

  • You can put in maintenance mode only a single ESXi host at a time in a management cluster of four ESXi hosts.
