White Paper

Managing Cisco UCS C-Series Rack Servers

What You Will Learn

Effective system management in the data center and across distributed locations requires support for a wide range

of environments and functionality. This document provides an overview of the two options customers have for

managing

. The first option is to use Cisco UCS Manager. The second option is

to use the Cisco

Integrated Management Controller (IMC) in standalone mode.

●

provides unified, embedded management of all software and hardware components of

the Cisco Unified Computing System

™

(Cisco UCS) across multiple rack-mount servers and thousands of

virtual machines. It manages Cisco UCS as a single entity through an intuitive GUI, a command-line

interface (CLI), or a unified API for comprehensive, programmable access to all Cisco UCS Manager

functions.

●

(IMC) is a baseboard management controller (BMC) in the

C-Series servers that provides embedded server management in the data center and across distributed

branch-office locations. It supports multiple management interfaces, including a web user interface (UI), a

command-line interface (CLI), and a unified API that is consistent with the one used by Cisco UCS

Manager. IMC also supports industry-standard management protocols, including Simple Network

Management Protocol (SNMP) v3 and Intelligent Platform Management Interface (IPMI) v2.0.

This paper also includes a section describing how IMC Supervisor enables centralized management for standalone

Cisco UCS C-Series Rack Servers as well as Cisco UCS S-Series Storage Servers and Cisco UCS E-Series

Servers located across one or more sites.

Some Background on Server Management

Most x86-architecture servers today include a management function commonly known as a baseboard

management controller (BMC). The BMC is usually embedded on the motherboard or main circuit board of the

server and includes a specialized service processor and firmware to monitor and manage the physical state of the

server hardware. BMC functions and standards are defined in the IPMI specifications, originally developed jointly

by Intel, Hewlett-Packard

Enterprise, Dell, and NEC. The specification is maintained and published at Intel’s

corporate website, helping ensure that BMC functions are consistently implemented on all x86 managed server

platforms.

Intel includes BMCs on its customer reference board (CRB) designs, which are given to original equipment

manufacturers (OEMs) and original design manufacturers (ODMs) to accelerate time to market and help ensure

compliance with industry standards such as IPMI. Cisco has added value to the basic BMC functions by

reengineering the BMC to make it an important part of the Cisco UCS architecture. This integration helps enable

powerful, industry-leading unified computing features and the use of service profiles for server provisioning and

change management.
