If you take a look at the NetBench methodology you will see that a single client represents multiple real world clients, depending on what your real world scenario is.

"NetBench scales applied loads by adding clients, and reports the aggregate throughput achieved across all clients. Each client generates requests representing the equivalent of ten or more real-world PCs in typical user environments. "

NetBench is a throughput measurement and the sole purpose of the clients in NetBench is to generate requests as fast a possible to measure the throughput of the system.

Here is another NetBench study for you using the latest FC and clustered toys:

>>...NetBench benchmark...

While certainly interesting, I was a little puzzled that a benchmark for what are supposedly enterprise filing systems topped out at 40 clients. What happens at 1000?

Most simply, '1000' doesn't happen in the NAS space. We're talking PC workstations, Word, Excel, Powerpoint, departmental email servers, PC support functions -- your standard corporate PC infrastructure world used by 80-90% of corporate employees these days. This is the space where NAS shines, relative to the current typical NT or Sun server with attached storage. This is DownSouth's space.

The '1000' occurs with big mission-critical enterprise applications, e.g. Siebel CRM applications or AT&T's network provisioning, monitoring, and billing applications or eBay's web server farms. Here big servers and SANs rule, and NAS is nowhere to be seen. This is Buck's space.

SANs are not applicable to the PC workstation space, except that many of the PCs, in addition to their MS Office Suite-style local apps, will be running client apps or browsers that feed or draw from big enterprise apps, e.g. a Support Call Center workstation.
