Microsoft's Exchange Online service has converged on the Open Cloud Server (OCS) and Project Olympus platforms for its server infrastructure. We are operating a fleet of 100s of 1,000s of OCP servers, with varying generations and SKUs of hardware, in over 100 datacenters worldwide. This session will cover how we discover, provision, monitor, diagnose, and repair our OCP servers, how we have engineered solutions to current OCP Redfish limitations, and discuss opportunities for the Hardware Management group to improve this experience.
