Cisco Unified Computing System Overview

The Cisco® Unified Computing System is a next-generation data center platform that unites compute, network, storage access, and virtualization 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).

Figure 1. The Cisco Unified Computing System Is a Highly Available Cohesive Architecture

Building on the success of the Cisco UCS B200 M1 and UCS B250 M1 servers, the Cisco UCS B200 M2 and UCS B250 M2 servers extend the capabilities of the Cisco Unified Computing System with the next generation of Intel processor technology: Intel® Xeon® 5600 series processors. These powerful processors deliver more cores, threads, and cache, all within a similar power envelope, with even faster payback, greater productivity, and better energy efficiency. When put into production, Cisco Unified Computing System and Intel Xeon 5600 series processors together offer further reductions in TCO, increased business agility, and another big leap forward in data center virtualization.

Product Overview

The Cisco UCS B-Series Blade Servers are crucial building blocks of the Cisco Unified Computing System, delivering scalable and flexible computing for today’s and tomorrow’s data center while helping reduce TCO.

The Cisco UCS B-Series Blade Servers are based on industry-standard server technologies and provide:

Up to two Intel Xeon Series 5600 multicore processors

Two optional front-accessible, hot-swappable SAS hard drives

Support for up to two dual-port mezzanine card connections for up to 40 Gbps of redundant I/O throughput

Industry-standard double-data-rate 3 (DDR3) memory

Remote management through an integrated service processor that also executes policy established in Cisco UCS Manager software

Local keyboard, video, and mouse (KVM) access through a front console port on each server

Out-of-band access by remote KVM, Secure Shell (SSH) Protocol, and virtual media (vMedia) as well as Intelligent Platform Management Interface (IPMI)

The Cisco UCS B-Series offers two blade server models: the Cisco UCS B200 M2 2-Socket Blade Server and the Cisco UCS B250 M2 2-Socket Extended Memory Blade Server (Figure 2). The Cisco UCS B200 M2 is a half-width blade with 12 DIMM slots for up to 192 GB of memory; it supports one mezzanine adapter. The Cisco UCS B250 M2 is a full-width blade with 48 DIMM slots for up to 384 GB of memory; it supports up to two mezzanine adapters.

Features and Benefits

The Cisco UCS B-Series Blade Servers are designed to increase performance, energy efficiency, and flexibility for demanding virtualized and nonvirtualized applications. Based on Intel Xeon 5600 Series processors, Cisco UCS BSeries Blade Servers adapt processor performance to application demands and intelligently scale energy use based on utilization.

Each Cisco UCS B-Series Blade Server uses converged network adapters (CNAs) for access to the unified fabric. This design reduces the number of adapters, cables, and access-layer switches while still allowing traditional LAN and SAN connectivity. This Cisco innovation reduces capital expenditures and operating expenses, including administrative overhead and power and cooling costs.

Cisco’s innovative service profile technology embedded in the Cisco UCS Manager, provisions Cisco UCS B-Series Blade Servers and their I/O properties (for more information, please see Cisco UCS Manager At-a-Glance). Infrastructure policies needed to provision servers and deploy applications, such as policies for power and cooling, security, identity, hardware health, and Ethernet and storage networking, are encapsulated in the service profiles. Use of service profiles helps reduce the number of manual steps needed for provisioning, the opportunities for human error, and server and network deployment times. In addition, service profiles improve policy consistency and coherency across the entire Cisco Unified Computing System.

The Cisco UCS B250 M2 increases performance and capacity for demanding virtualization and large-data-set workloads with up to 384 GB of industry-standard memory. This technology offers a cost-effective memory footprint for demanding workloads.

The Cisco UCS B200 M2 balances simplicity, performance, and density for production-level virtualization and other mainstream data center workloads.

Table 2 summarizes the features and benefits of the Cisco UCS B-Series.

Table 2. Features and Benefits



Unified fabric

Decreases TCO by reducing the number of network interface cards (NICs), host bus adapters (HBAs), switches, and cables needed

Service profile support

Contains all the infrastructure policies required to deploy applications and provision servers
Helps reduce the number of manual steps required and the opportunity for human error, improving server policy consistency and coherency.
Allows servers and support infrastructure to be provisioned in minutes instead of days, shifting IT’s focus from maintenance to strategic initiatives


Requires no configuration; like all components in the Cisco Unified Computing System, blades are automatically recognized and configured by Cisco UCS Manager

Cisco Extended Memory Technology
