IBM Flex System and PureFlex System Network Implementation

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 are 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 that you can achieve faster time to value.

If you want a preconfigured, preintegrated infrastructure with integrated management and cloud capabilities, factory tuned from IBM with x86 and Power Systems™ hybrid solution, IBM PureFlex System is the answer.

In this IBM Redbooks® publication, which is aimed at system and network administrators, we show the design and architecture, how to configure hosts and switches, maintain, and troubleshoot using the IBM Flex System™ Ethernet I/O modules (EN2091 1Gb Ethernet Scalable Switch and EN4093R 10Gb Scalable Switch).
