IBM Flex System and PureFlex System Network Implementation with Cisco Systems

Book Description

To meet today's complex and ever-changing business demands, you need a solid foundation of server, storage, networking, and software resources. It must be simple to deploy and able to quickly and automatically adapt to changing conditions. You also need access to, and the ability to take advantage of, broad expertise and proven best practices in systems management, applications, hardware maintenance, and more.

IBM® PureFlex™ System is part of the IBM PureSystems™ family of expert integrated systems. It combines advanced IBM hardware and software along with patterns of expertise and integrates them into three optimized configurations that are simple to acquire and deploy. With the PureFlex System, you can achieve faster time to value.

If you want a pre-configured, pre-integrated infrastructure with integrated management and cloud capabilities, factory tuned from IBM with x86 and Power hybrid solution, IBM PureFlex System is the answer.

In this IBM Redbooks® publication, the examples use a Cisco Nexus 5000 Series Switch, although any configurations should also apply to the Cisco Nexus 7000 Series Switch too. However, it is wise to check as there might be minor differences.

This book also covers the different variations for the implementation of these use cases when you use Cisco Catalyst Series Switches.
