Cisco Unified Computing System
fuses access layer networking and servers. This high-performance,
next-generation server system provides a data center with a high degree of
workload agility and scalability.
The hardware and software components support Cisco's unified fabric,
which runs multiple types of data center traffic over a single converged
The simplified architecture of
reduces the number of required devices and centralizes switching resources. By
eliminating switching inside a chassis, network access-layer fragmentation is

Ethernet and Fibre Channel over Ethernet (FCoE) links.
This radical simplification reduces the number of switches, cables, adapters, and management points by up to

Cisco UCS 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
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
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:
Deploy new servers to meet unexpected workload demand and
rebalance resources and traffic.
Shut down an application, such as a database management system, on
one server and then boot it up again on another server with increased I/O
capacity and memory resources.
Optimized for Server Virtualization
has been optimized to implement VM-FEX technology. This technology provides
improved support for server virtualization, including better policy-based
configuration and security, conformance with a company's operational model, and
accommodation for VMware's VMotion.
