By partitioning a server logically by memory, processor,
and disk, VMWare facilitated much fuller use of servers by opening the possibility of running
multiple applications in parallel on a single server, thus enabling consolidation of servers. Sutten had
also been pushing to better understand their Wintel space to see if performance could be enhanced by
adding more Web servers in strategic locations. The tool they currently used for this analysis was
Aleita. It pulled the system and performance log data from the Wintel environment to look at what
CPU utilization and aggregate format would be like under different simulated traffic loads and
configura lions. They used it to aggregate information across a group of servers all serving the same
application. They were transitioning to Mercury, with their agentless monitoring tools, to get this
information in real time in terms of monitoring, alerting, and reporting.
