Cisco Unified Computing System (UCS) Manager provides unified, embedded management of all software and hardware components in the Cisco UCS.Through its unified, embedded, policy-based, and ecosystem-friendly approach, Cisco UCS Manager helps reduce management and administration expenses, which are among the largest items in most IT budgets. The UCS Manager can manage up to 160 servers and thousands of Cisco UCS components in multiple chassis. The embedded management software and all the managed components are part of a UCS domain. With Cisco UCS Central, management can be extended globally to thousands of servers in multiple domains.

Cisco UCS has many physical components, all managed by Cisco UCS Manager (Figure 1). Cisco UCS is a vextgeneration data center platform that unifies computing, networking, storage access, and virtualization resources into a cohesive system designed to reduce total cost of ownership (TCO) and increase business agility. The system integrates a low-latency, lossless 10 Gigabit Ethernet unified network fabric with enterprise-class, x86-architecture servers. It is a scalable, multichassis platform in which all resources are integrated into a unified management domain.

The architecture of Cisco UCS Manager consists of multiple layers with well-defined boundaries. Externalinterfaces provide communication with the outside world (Figure 2). The data management engine (DME) is the central service that manages the components of Cisco UCS. Application gateways act as hardware abstraction layers between the DME and the managed endpoints. The endpoints are the actual devices or entities that are managed by Cisco UCS Manager, but they are not considered as part of Cisco UCS Manager itself.
