Ethernet and Fibre Channel protocols over 10 Gigabit Cisco Data Center Ethernet
and Fibre Channel over Ethernet (FCoE) links. This radical simplification
reduces the number of switches, cables, adapters, and management points by up
to two-thirds. All devices in a

domain allows you to quickly align computing resources in the data center with
rapidly changing business requirements. This built-in flexibility is determined
by whether you choose to fully implement the stateless computing feature. Pools
of servers and other system resources can be applied as necessary to respond to
workload fluctuations, support new applications, scale existing software and
business services, and accommodate both scheduled and unscheduled downtime.
Server identity can be abstracted into a mobile service profile that can be
moved from server to server with minimal downtime and no need for additional
network configuration. With this level of flexibility, you can quickly and
easily scale server capacity without having to change the server identity or
reconfigure the server, LAN, or SAN. During a maintenance window, you can
quickly do the following:

improved support for server virtualization, including better policy-based

accommodation for VMware's VMotion.
Cisco UCS Manager
Cisco UCS Manager is
embedded software that resides on the fabric interconnects, providing complete
configuration and management capabilities for all of the components in the
Cisco UCS system. This configuration information is replicated between the two
fabric interconnects, providing a highly available solution for this critical
function. The most common way to access UCS Manager for simple tasks is to use
a Web browser to open the Java-based GUI. For command-line or programmatic
operations against the system, a command-line interface (CLI) and an XML API
are also included with the system.
The Cisco UCS Manager
GUI provides role-based access control (RBAC) to allow multiple levels of users
granular administrative rights to system objects. Users can be restricted to
certain portions of the system based on locale, which corresponds to an
optional organizational structure that can be created within the system. Users
can also be classified based on their access levels or areas of expertise, such
as “Storage Administrator,” “Server Equipment Administrator,” or “Read-Only”.
RBAC allows the comprehensive capabilities of the Cisco UCS Manager GUI to be
properly shared across multiple individuals or teams within your organization
in a flexible, secure manner.
Cisco UCS Manager
provides unified, embedded management of all software and hardware components.
Every instance of Cisco UCS Manager and all of the components managed by it
form a domain. For organizations that deploy multiple Cisco UCS domains, Cisco
UCS Central software providesa centralized user interface that allows you to
manage multiple, globallydistributed Cisco UCS domains with thousands of
servers. Cisco UCS Central integrates with Cisco UCS Manager and utilizes it to
provide globalconfiguration capabilities for pools, policies, and firmware.
