Claim 8:
9. A system for high availability (HA) management in an open radio access network (O-RAN) comprising:
a plurality of local HA managers deployed a cell site O-RAN cloud (O-Cloud) comprising multiple O-RAN radio units (O-RUs), each O-RU comprises one or more radio-frequency (RF) clusters, one or more computation clusters, and one or more interface clusters, each local HA manager couples to a corresponding O-RU, the plurality of local HA managers are configured for:
instantiating one or more O-RU instances, with redundancy, on the cell site O-Cloud to serve one or more users, the one or more O-RU instances involve one or more O-RUs among the multiple O-RUs, each O-RU instance comprises at least one RF cluster handling RF front end, at least one computation cluster handling digital front end (DFE) and low PHY, and at least one interface cluster handling fronthaul transport to/from an O-RAN distributed unit (O-DU); and
monitoring, using the local HA manager for each of the one or more O-RU instances, instance performance of the one or more O-RU instances for failure prediction/detection; and

a centralized HA manager deployed on a regional cloud for a control unit (O-CU) of the O-RAN, the centralized HA manager couples to the plurality of local HA managers for hierarchical HA management;
wherein in response to a failure for one or more O-RU instances being detected or predicted, instantiating one or more new O-RU instances in the same O-RU with detected or predicted O-RU instance failure or in another O-RU within the cell site O-Cloud.
