Analytics nodes, witness nodes, and remote collectors have various hardware requirements for virtual machines and physical machines.

The following table specifies the components to install on each server profile in your deployment, and the required hardware specifications.

Table 1. Hardware Requirements for System Components
Server Roles Virtual CPU Memory CPU Requirements Storage Requirements
Medium Analytics Node 8 vCPU 32 GB 2.0 GHz minimum, 2.4 GHz recommended 1875 IOPS
Large Analytics Node 16 vCPU 48 GB 2.0 GHz minimum, 2.4 GHz recommended 3750 IOPS
Standard Remote Collector 2 vCPU 4 GB 2.0 GHz minimum, 2.4 GHz recommended N/A
Large Remote Collector 4 vCPU 16 GB 2.0 GHz minimum, 2.4 GHz recommended N/A
Witness Node 2 vCPU 8 GB 2.0 GHz minimum, 2.4 GHz recommended N/A
Small vRealize Application Remote Collector 4 vCPU 8 GB 2.0 GHz minimum, 2.4 GHz recommended N/A
Medium vRealize Application Remote Collector 8 vCPU 16 GB 2.0 GHz minimum, 2.4 GHz recommended N/A
Large vRealize Application Remote Collector 16 vCPU 24 GB 2.0 GHz minimum, 2.4 GHz recommended N/A

Storage requirements are based on the maximum supported resources for each node.

vRealize Operations Manager has a high CPU requirement. In general, the more physical CPU that you assign to the analytics cluster, the better the performance. You must use a minimum of eight physical CPU dual socket hosts.
