Executive Summary

IT departments are consolidating servers and implementing virtualization to simplify their environments and lower the total cost of ownership. Some organizations are achieving consolidation ratios of as high as 100:1, and 20:1 consolidation is commonplace, using VMware and multi-core server technology. But success in reducing the number of servers, and the concomitant reduction in management and environmental costs, has a price: each reduction in physical server presence also subtracts a number of NIC ports. A proliferation of virtual machines on a single server competes for that server's resources, often resulting in I/O bottlenecks.
