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.
|Server Roles||Virtual CPU||Memory||Storage Requirements|
|Small Analytics Node||4 vCPU||16 GB||1276 IOPS|
|Medium Analytics Node||8 vCPU||32 GB||1875 IOPS|
|Large Analytics Node||16 vCPU||48 GB||3750 IOPS|
|Extra Large Analytics Node||24 vCPU||128 GB||12758 IOPS|
|Standard Remote Collector||2 vCPU||4 GB||N/A|
|Large Remote Collector||4 vCPU||16 GB||N/A|
|Witness Node||2 vCPU||8 GB||N/A|
|Small vRealize Application Remote Collector||4 vCPU||8 GB||N/A|
|Medium vRealize Application Remote Collector||8 vCPU||16 GB||N/A|
|Large vRealize Application Remote Collector||16 vCPU||24 GB||N/A|
CPU requirements are 2.0 GHz minimum. 2.4 GHz is recommended. 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. The cluster will perform better if the nodes stay within a single socket.
