WinHEC attendees could still see Windows Server 2008 R2 in action during Bill Laing's keynote. Onstage with Laing were two big-box servers, including the Hewlett-Packard Integrity Superdome Server using Intel Itanium x64 processors plus two terabytes of memory and the IBM x3950 M2 Server running Intel Xeon x86 processors.
Other enterprise servers tested using Windows Server 2008 R2 included the NEC AsAmA and Unisys ES7000/one.
Laing emphasized that the Windows Server 2008 R2 build is capable now of scaling operations from 64 logical processors (the current limit) to 256 logical processors on the Superdome Server. With the IBM x3950 M2 Server, the system scaled up to 192 available cores.
The keynote also demonstrated what to do with all of this computing power by running a live demo of a massive SQL Server application that was occupying about 82 percent of the Superdome Server's capacity. Within a few seconds, the load balanced automatically across the 256 logical cores when the demo was run. A graph of the system's performance was relatively flat across all of the processors.
