Tom Aurand - ESCON to FICON
Planning and modeling ESCON to FICON conversions:
Mr. Aurand will explore qualitatively and semi-quantitatively the effects of FICON channel
implementation on channel and device performance. He will present a review of RMF device
response time components, the effect FICON has on each, and the background reasons for these effects. A semi-quantitative discussion then will center on an approach to designing an optimum FICON configuration, including:

• How many channel paths will I need from the processor to the director?
• How many paths must I have from the director to the control unit?
• What target channel utilization should I have?
• What can I expect the impact on device performance to be?

Tom Thompson - Optimizing Server Consolidations
Consolidation/Relocation of servers without over-spending and adversely impacting application
response times is a daunting task. In this session we will present best-practice approaches that address this challenge by modeling enterprise infrastructures with live data sources including server workloads, network configurations, and application traces. These approaches provide a framework to:

• Aggregate server resources to achieve better utilization
• Reduce costs of maintaining multiple data-centers
• Avoid under-provisioning, or over-provisioning (networks and servers) while meeting SLAs
• Evaluate many consolidation/re-location alternatives quickly without expensive lab setups
• Accommodate changes in traffic patterns due to re-location of servers
