Cisco UCS 5100 Series Blade Server Chassis

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 10/40 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).

With the Cisco UCS 6324 Fabric Interconnect, the management flexibility and cable reduction of the full-scale Cisco UCS solution is now available in a single-chassis implementation. The Cisco UCS 6324 Fabric Interconnect allows a single Cisco UCS chassis to be managed and configured in the same way as a full-scale Cisco UCS solution, providing the advantages of Cisco UCS to smaller businesses and remote sites.

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.

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-width and full-width blade form factors.

Four hot-swappable power supplies are accessible from the front of the chassis, and single-phase 2500 W AC, 2500 W –48 VDC, and 2500 W 200 - 380 VDC power supplies and chassis are available. These power supplies are up to 94 percent efficient and meet the requirements for the 80 Plus Platinum rating. The power subsystem 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 that can support either Cisco UCS 2000 Series Fabric Extenders or the Cisco UCS 6324 Fabric Interconnect. 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 support 40 Gigabit Ethernet standards with the 2304 Fabric Extender and 25 Gigabit Ethernet standards with the Cisco UCS 2408 Fabric Extender.

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, the chassis uses 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 M5 and B480 M5 Blade Servers.

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 managing servers, networking, and storage from a single interface

Unified fabric

  Reduces 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, 2200, 2300 or 2400 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

Support for Cisco UCS 6324 Fabric Interconnect

  Allows the simplicity and consistency of a Cisco UCS managed solution to be economically achieved for single-chassis implementations


  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, fabric interconnects, and future blade servers
  Supports up to 2 x 40 Gigabit Ethernet for every half-width blade server slot when used in high-availability mode
  Provides 8 blades with 1.2 terabits (Tb) of available Ethernet throughput to meet 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 6200 Series, 6300 or 6400 Series Fabric Interconnects, and UCS 2200, 2300 or 2400 Series Fabric Extenders and blades servers, or the UCS 6324 Fabric Interconnect and blade servers to function in this integrated environment.
