In fact, reliability and
performance-metrics gathering is the cornerstone of any proactive systems management
strategy. If you??™ve inherited a poorly managed server infrastructure, you may not like
what the data is showing you, but at least you have the information you need to make
some good decisions about where to focus your attention. In fact, such information is
the most effective way to justify to upper management why you need to spend money

supplement your proposal with data showing how your server capacity is shrinking and
the potential risks involved if this issue isn??™t resolved. In addition to all this, as we move
more toward virtualization, it is important that we have good performance metrics to
guide us in which servers and how many servers can be hosted on a single host node.
WINDOWS SYSTEM RESOURCE MANAGER
Windows System Resource Manager was part of Windows Server 2003 Enterprise and
Datacenter editions and was available on a separate CD. In Windows Server 2008, WSRM
is part of Windows Server 2008 Enterprise and Datacenter editions. The major difference

the Server Manager interface rather than having to run it from a separate disc.
