Cisco Unified Computing System Overview

The Cisco Unified Computing System (Cisco UCS) is a next-generation data center platform that unites 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. The system is an integrated, scalable, multichassis platform in which all resources participate in a unified management domain (Figure 1).

Product Overview

The Cisco UCS 5100 Series Blade Server Chassis is a crucial building block of the Cisco Unified Computing System, delivering a scalable and flexible blade server chassis for today’s and tomorrow’s data center while helping reduce TCO.

Cisco’s first blade server chassis offering, the Cisco UCS 5108 Blade Server Chassis (Figure 2), is six rack units (6RU) high and can mount in an industry-standard 19-inch rack. A chassis can house up to eight half-width Cisco UCS B-Series Blade Servers and can accommodate both half- and full-width blade form factors.

Four single-phase, hot-swappable power supplies are accessible from the front of the chassis. These power supplies are 92 percent efficient and can be configured to support nonredundant, N+1 redundant, and grid-redundant configurations. The rear of the chassis contains eight hot-swappable fans, four power connectors (one per power supply), and two I/O bays for Cisco UCS 2208XP Fabric Extenders. A passive midplane provides up to 80 Gbps of I/O bandwidth per server slot and up to 160 Gbps of I/O bandwidth for two slots. The chassis is capable of supporting future 40 Gigabit Ethernet standards.

Features and Benefits

The Cisco UCS 5108 Blade Server Chassis revolutionizes the use and deployment of blade-based systems. By incorporating unified fabric, integrated, embedded management, and fabric extender technology, Cisco UCS allows the chassis to use fewer physical components, has no need for independent management, and enables greater energy efficiency than traditional blade server chassis. This simplicity eliminates the need for dedicated chassis management and blade switches, reduces cabling, and enables Cisco UCS to scale to 20 chassis without adding complexity. The Cisco UCS 5108 chassis is a critical component in delivering the Cisco UCS benefits of data center simplicity and IT responsiveness.

In addition, the Cisco UCS 5108 chassis has the architectural advantage of not having to power and cool excess switches in each chassis. With a larger power budget per blade server, Cisco can design uncompromised expandability and capabilities in its blade servers, as evidenced by the new Cisco UCS B200 M3 Blade Server, with its leading memory slot and drive capacity, and the Cisco UCS B230 M2 Blade Server, with its industry-leading 32-DIMM memory density in a half-width form factor.

Table 1 summarizes the features and benefits of the Cisco UCS 5108.

Table 1. Features and Benefits



Management by Cisco UCS Manager

Reduces TCO by removing management modules from the chassis, making the chassis stateless
Provides a single, highly available management domain for all system chassis and rack servers, reducing administrative tasks

Unified fabric

Decreases TCO by reducing the number of network interface cards (NICs), host bus adapters (HBAs), switches, and cables that need to be managed, cooled, and powered

Support for one or two Cisco UCS 2100 or 2200 Series Fabric Extenders

Eliminates switches from the chassis along with complex configuration and management of those switches, allowing a system to scale without adding complexity and cost
Allows use of two fabric extenders for both redundancy and aggregation of bandwidth
Enables bandwidth scaling based on application needs; blades can be configured from 1.25 Gbps to 40 Gbps or more


Requires no configuration; like all Cisco UCS components, chassis are automatically recognized and configured by Cisco UCS Manager

High-performance midplane

Provides investment protection for new fabric extenders and future blade servers
Supports up to 2x 40 Gigabit Ethernet for every blade server slot when used in high-availability mode
Provides 8 blades with 1.2 terabits (Tb) of available Ethernet throughput for future I/O requirements
Provides reconfigurable chassis to accommodate a variety of current and future blade server form factors and functions

Redundant hot-swappable power supplies and fans

Provides high availability in multiple configurations
Increases serviceability
Provides uninterrupted service during maintenance

Hot-pluggable blade servers and fabric extenders

Provides uninterrupted service during maintenance and server deployment

Comprehensive monitoring

Provides extensive environmental monitoring on each chassis
Allows use of user thresholds to optimize environmental management of the chassis

Efficient front-to-back airflow

Helps reduce power consumption and increase component reliability

Tool-free installation

Requires no specialized tools for chassis installation
Provides mounting rails for easy installation and servicing

Mixed blade configurations

Allows up to 8 half-width or 4 full-width blade servers, or any combination thereof, for outstanding flexibility


The Cisco UCS 5100 Series is designed for use in the Cisco UCS environment and requires Cisco UCS Manager, UCS 6100 or 6200 Series Fabric Interconnects, UCS B-Series Blade Servers, and UCS 2100 or 2200 Series Fabric Extenders to function in this integrated environment.
