  • IDC research shows that customers are expecting to achieve utilization rates of60–80% on their hardware. This goal, in combination with future hardware and softwareimprovements in multicore processor technology, memory addressability, and I/Ooptimization, will allow customers to continue to improve their VM density levels. Alsocritical to the success of virtualization are improvements in reliability, particularly asgreater numbers of applications become dependent on fewer numbers of physicalservers.

Cisco Confidential 3Key Trends Impacting the Data Center• Customers expect increased hardware utilization rates,60-70% per IDC, network bandwidth expected to increase fivefold by 2017*• Application workloads continue to consolidate onto more highly utilized servers running Vmware(VM density per server increasing dramatically).• Migration to servers with multi core & socket CPU architectures (e.g., Intel Romley) and highlydense extensible memory architectures like UCS.• Increased I/O consolidation and convergence of network and storage traffic onto losslessEthernet based fabrics (FCoE)• “Perfect Storm” of factors at server edge driving explosion of bandwidth towards the upper layersof the network in the foreseeable futureSource: Crehan Research “Server-Class Networking Bandwidth to Increase Five-Fold in Five Years
