Installation Node Requirements
Before installing OmniData, deploy necessary components in the cluster environment by following instructions in OS and Software Requirements.
Planning Installation Nodes
- During the installation, plan a root CA server for issuing authentication certificates to HAF compute and offload nodes. If there is only one node, perform all operations on the node.
- When using the root CA server to issue certificates, ensure that the time on each node is synchronized. Otherwise, the certificate verification fails due to the system time difference. You can configure NTP for synchronization.
