With ever-increasing demand on data centers, vendors started focusing on different aspects of server and networking hardware consolidation; however, most of the ad hoc solutions were based upon existing products that were not designed from the ground up for integration from the consolidation perspective and failed to address the requirements of a data center as a whole. Hence, the management of these amalgamated solutions was a nightmare for the IT administrator.

Cisco entered the blade server market with a holistic approach to blade server design. With a strong background in networking and storage products, Cisco developed a cohesive solution consolidating compute, network, and storage connectivity components along with centralized management of these resources. The purpose of Cisco UCS is to reduce the total cost of ownership (TCO) and improve manageability, scalability, and flexibility.

Cisco introduced the idea of stateless computing with its blade server design. Cisco blade servers do not need any initial configuration. Blade identity UUID, NICs, MAC addresses, storage WWN numbers, firmware, and BIOS settings are all abstracted from Unified Computing System Manager (UCSM), the management software running on the Fabric Interconnects.

Time for provisioning servers dramatically improves, as the servers can be provisioned using UCSM software even before they are physically available. Once the server is physically installed, it will abstract its identity from UCSM. Using server configuration templates, it is possible to create a server template once and apply it on hundreds of servers.

Replacing servers also becomes very easy. Since the servers are stateless, as soon as a replacement server is installed, it will abstract all the configuration of the old server from the associated service profile and will be available for use. Servers can also be easily migrated for different roles and workloads.

Virtualization in the form of modern bare-metal hypervisors is a major breakthrough for the optimal utilization of computational resources. The Cisco UCS solution supports all major hypervisor platforms, including VMware ESX/ESXi, Microsoft Hyper-V, and Citrix XenServer. Support and integration with VMware vSphere is very strong. UCSM can be integrated with vCenter to abstract and manage features at the individual virtual machine (VM) level. Leveraging the benefits of virtualization and increasing the density of physical servers, UCS can scale up to thousands of VMs.

Cisco UCS servers are available in two categories: B-Series blade servers and C-Series rack-mount servers. Both form factors are designed using the same industry-standard components and can address different computational requirements. Both B-series blade servers and C-Series rack-mount servers are designed using Intel® Xeon® CPUs. B-series servers are managed through UCSM, whereas C-Series servers can either be individually managed or can be integrated to UCSM.

Cisco also introduced patented extended memory technology for two CPU socket servers to increase the total amount of memory support, which could be more than double the amount of memory as compared to the industry standard for two-socket servers. Virtualized workloads can leverage this extra memory to support an even greater density of virtual machines in a reduced physical footprint, thus resulting in reduced capital expenditure (CAPEX) and operational expenditure (OPEX) costs. Extended memory technology is available in both B-Series blade servers and C-Series rack-mount servers.

Key benefits

Learn how to reduce equipment and operating costs, consolidate resources, and automate data center processes

Eliminate manual, time-consuming tasks that were traditionally required to connect servers in data centers

A practical hands-on guide that will help you to deploy servers and application stacks with ease

Description

Cisco Unified Computer System (UCS) is a powerful solution for modern data centers and is responsible for increasing efficiency and reducing costs. This hands-on guide will take you through deployment in Cisco UCS. Using real-world examples of configuring and deploying Cisco UCS components, we’ll prepare you for the practical deployments of Cisco UCS data center solutions. If you want to develop and enhance your hands-on skills with Cisco UCS solutions, this book is certainly for you. We start by showing you the Cisco UCS equipment options then introduce Cisco UCS Emulator so you can learn and practice deploying Cisco UCS components. We’ll also introduce you to all the areas of UCS solutions through practical configuration examples. Moving on, you’ll explore the Cisco UCS Manager, which is the centralized management interface for Cisco UCS. Once you get to know UCS Manager, you’ll dive deeper into configuring LAN, SAN, identity pools, resource pools, and service profiles for the servers. You’ll also get hands-on with administration topics including backup, restore, user’s roles, and high availability cluster configuration. Finally, you will learn about virtualized networking, third-party integration tools, and testing failure scenarios. By the end of this book, you’ll know everything you need to know to rapidly grow Cisco UCS deployments in the real world.
