SUMMARY
Whew! Looks like backing up and restoring Exchange 2007 databases is much more complicated than it appears to be In this chapter, you learned how to back up and restore an Exchange database using the Windows Backup Utility, the disaster recovery processes that are new to Exchange 2007, and a number of advanced topics, including how to plan your backup strategy and the pitfalls to avoid when restoring a database In the next chapter, we ll move our focus away from disaster recovery to Exchange 2007 Server performance tuning
Performance Tuning Exchange Server 2007
Microsoft Exchange Server 2007: A Beginner s Guide
t this point in the book, if you were to read it from front to back and implement your environment with each chapter, you would have a completely functional, well-designed Exchange 2007 organization Once that s accomplished, the main concern would be the performance of your Exchange servers Day-to-day performance of Exchange will most likely be considered good (as long as no users call complaining that their e-mail is too slow, right ) However, the question still remains: How well is your Exchange environment running The Exchange-performance litmus test previously mentioned (no complaints equals good performance) is somewhat of a commentary on the reactive method by which many administrators gauge the performance of Exchange It would be far more advantageous to actually monitor Exchange s performance Performance monitoring of Exchange is not only a good idea, it can also be critical for the maintenance of your environment Let me ask a few questions about your current Exchange environment to see whether yours will be a success: When do you project your mailbox store drive will run out of disk space At what time of day or day of week is your Exchange server s processor busiest How many users logged on to Outlook Web Access (OWA) yesterday
Knowing the answers to these questions won t just help your Exchange server run more efficiently it can also make the difference between the life and death of an Exchange server This chapter will first cover some basic information on performance monitoring using the Exchange Server Performance Monitor (the Windows 2003 System Monitor tool prepopulated with Exchange-related data) Then we will look at Exchangespecific counters to monitor, as well as how to make the information gathered work for you Lastly, we ll look at the new Performance Troubleshooter tool and how it can simplify the process of improving Exchange performance
PERFORMANCE MONITORING BASICS
Before you can begin monitoring your Exchange servers, you need to know a little about performance monitoring in general We ll begin by focusing on monitoring Windows 2003 in general Then we ll see how we can apply what we ve learned to monitoring Exchange 2007 Performance monitoring is the process of collecting performance data for the purpose of analyzing resource usage There are four basic reasons you will want to monitor the performance of your Exchange server: To diagnose problems To test configuration changes To identify the effect the server s workload has on its resources To forecast hardware needs

Performance Tuning Exchange Server 2007
Monitoring Resources
There are four basic hardware resources you should monitor: Memory Processor Disk subsystem Network subsystem
Every server has a finite amount of these resources with which to work that is, you can itemize exactly how much of each resource the server has for example, 2 gigabytes (GB) of random access memory (RAM), 500 GB of disk space, a 3-gigahertz (GHz) processor, and so on With Exchange 2007 (and, therefore, Windows 2003), a delicate balance must be maintained so that you do not overconsume one resource to the detriment of another For example, if you are using up too much memory, the server will use the paging file to compensate, causing two repercussions: Additional disk space may be used if the paging file needs to grow Disk performance suffers, because your disk subsystem is spending time away from normal operations to read from and write to the paging file
This example demonstrates the fact that you need to watch your server s resource usage in order to keep it running at peak performance In addition to the basic resources, you will probably want to monitor application-specific information (in our case, Exchange 2007) in order to ensure that Exchange 2007 is running at peak performance
