More information can be found at: http://www.microsoft.com/exchange/support/deployment/planning/deploy.asp?A=5&B=1 What the Benchmarks Don't Tell You It is important to understand that benchmarks such as these are designed to give Microsoft Exchange Server implementation planners baseline references for understanding the capabilities of hardware platforms from a single vendor such as Compaq or other competing hardware vendors. When interpreting these benchmarks, however, two things should be kept in mind. First, consider whether benchmarks are performed on what can be referred to as customerdeployable configurations. A hardware vendor may publish a result that is based on a platform or configuration that should not be deployed in a real-world Exchange Server deployment. For example, many vendors have published results using disk subsystems configured with RAID0 disk arrays. While RAID0 does provide the highest levels of disk subsystem performance, it fails to provide any protection against data loss. In addition, most vendors, including Compaq, conduct benchmarks for Microsoft Exchange Server that are single-server in nature. In the realworld of messaging, customer sites are usually multi-server and multi-site. Single-server, singlesite lab benchmarks do not account for the communication demands from other servers on the network. ECG1080898
