Intel's Xeon 7500/6500 processor series brings the biggest leap in performance in Xeon's history.
This level of performance enables consolidation of a ton of older servers onto significantly fewer Xeon 7500/6500 generation platforms...saving a considerable amount of money.
For example, IT managers can consolidate up to 20 older single-core 4-socket servers onto a single Xeon 7500 4-socket system representing a 4-socket to 4-socket consolidation ratio up to 20:1. The resulting savings from reduced power usage and OS licensing costs can show a payback of less than a year on the cost of the new server. That's a fantastic payback....and if application software costs and other savings are included the ROI is even greater.
Similarly favorable 2-socket consolidation ratios are possible by moving workloads off of older 2-socket systems and onto Xeon 7500/6500 servers.
A good example of this comes from Dell. Their engineering solutions teams recently published three technical white papers showing the benefits of consolidating database and virtualization workloads running on older 2-socket servers onto their new R810 server based on the Xeon 7500 processor series. The R810 is a pretty cool, innovative platform with Dell's FlexMem Bridge Technology that allows full access to the entire system memory whether the system is populated with just 2 or the full 4 sockets.
