Are you planning to deploy Microsoft® Exchange Server 2003? Are you concerned about availability, fault tolerance and performance? If so, it is critical that you understand how to optimize your storage system for Exchange Server 2003, regardless of the size of your organization.

Disk subsystem bottlenecks cause more performance problems than server-side CPU or RAM deficiencies, and a poorly designed disk subsystem can leave your organization vulnerable to hardware malfunctions. Specifically, your disk subsystem is performing poorly if it is experiencing:

• Average read and writes latencies over 20 ms
• Latency spikes over 50 ms that last for more than a few seconds.

This topic is elaborated in this guide as follows:

• What causes Exchange Disk I/O?
