Ethernet Fabrics and the Cloud: Avoid the Fog and Smog Dr. Steve Guendert Brocade Communications Dr. Casimer DeCusatis IBM Corporation February 7, 2013 Session 12735
Abstract This session will discuss Ethernet Fabrics: what they are, what their business and technical value is, and how to implement them as part of your cloud architecture including with System z. It will also dispel misconceptions to clear the smog and fog from the cloud. The focus will be on the Open Data Center Interoperable Network (ODIN) model. 2
Agenda-Overview • Introduction • A need for progress in data center network design • Data center network transformation • What is an Ethernet Fabric? • The Open Datacenter Interoperable Network (ODIN) • System z • Conclusion and questions. 3
The Need for Progress is Clear 30 percent 85% 42 percent Worldwide, buildings Energy costs alone In distributed computing represent about 30% of consume 42% of all 85% of computing an office building’s total electricity – up to 50% of capacity sits idle operating costs which is wasted 18% 50%+ 20x More than half of our clients have Anticipated annual Growth in density of plans in place to build a new data increase in energy costs technology during this center/network facilities as they decade. Energy costs are out of power, cooling and/or higher than capital space outlay
Forecasted evolution of • Rapidly increasing demand for 10 Gbps Ethernet (IEEE, 2007) server connections • Transition to 10G is happening now and will be mainstream from 2012 • Broad deployment of 10GBaseT will simplify DC infrastructure • by easier server connectivity, while delivering bandwidth needed for heavy virtualization and IO intensive applications • Server Virtualization • To stop wastage of server CPU resources • Exploding East-West traffic volumes • to support multitier applications and high performance computing • Proliferation and mobility of Virtual Machines • to address fluctuating workload Forecasted evolution of FibreChannel (Infornetics) • by on-demand starting, moving and (hopefully also) decommissioning VMs • Increased complexity • Drives focus to maintaining the infrastructure • Rather than to adding business value by leveraging new infrastructure services
