With an eye toward server consolidation, HP has developed the optional ProLiant Essentials Workload Management Pack, designed to harness and manage the server resources. The main component of the Workload Pack is the Resource Partitioning Manager, which lets administrators allocate the number of processors and amount of memory a process or application can use.
I created a partition for Internet Information Server (IIS) and allocated four of the 16 virtual processors to IIS, then hit the server with traffic from the lab's Spirent Communications WebAvalanche stress-testing appliance. As the HTTP traffic sent to the server steadily increased, CPU utilization also increased across the four processors, as well as on the one processor handling the operation of the Resource Manager. The remaining 11 processors were unaffected and available for other jobs.
