Follow these best practices for deploying vRealize Operations.
Deploy vRealize Operations to a supported infrastructure
Ensure that you are deploying vRealize Operations to a supported infrastructure as earlier versions may no longer be supported. Refer to the VMware Product Interoperability Matrices for platforms supported with vRealize Operations
Do not modify or install third party applications on the appliance
When using the virtual appliance, installation or modifications of third-party applications is unsupported and may cause problems to vRealize Operations.
Deploy the VA with FQDN
Register a fully qualified domain name for the vRealize Operations node. Simply using a hostname may not properly resolve and there may be communication problems with the node.
Use Thick Provisioning Eager Zeroed
When deploying nodes, set the disk provisioning to “Thick Provision Eager Zeroed” for most optimum performance.
Leverage Remote Collectors
Use remote collectors where possible to navigate firewalls, reduce the bandwidth across data centers, connect to remote data sources, or reduce the load on the vRealize Operations analytics cluster.
