IBM Flex System and PureFlex System Network Implementation with Juniper Networks

Book Description

To meet today's complex and ever-changing business demands, you need a solid foundation of server, storage, networking and software resources that is simple to deploy and can 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, which is a part of the IBM PureSystems™ family of expert integrated systems, 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 so 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, we use EX4500 core switches to demonstrate interoperability with the System Networking switches (RackSwitch™ G8264 top of rack switch and the Flex system fabric EN4093 10Gb scalable switch).

We also describe a redundant environment using QFX3500 switches running IBM Virtual-Link Aggregation Group (MC-LAG/vLAG) and Juniper Multi- Chassis-Link Aggregation Group.
