"As your small-to-midsize company grows, how can you make sure your network of servers grows to fit? You've probably read horror stories about companies that cannot cope. You're probably already experiencing network outages, delayed access to key files and general problems with your setup...."
"Linux holds up very well against Windows NT in terms of multiprocessor support. A VA Linux Systems four-processor box far outperformed a similar multiprocessor box (same processor types and speeds) in a SPEC rate integer benchmark test. (As is true with all benchmarks, though, how well a system works on your computing tasks forms the only real benchmark for your organization.)"
"Along with adding processors to a system, you can combine similar systems together into clusters to increase performance on certain tasks. A Linux Beowulf cluster (http://www.beowulf.org) from IBM, for example, tied the fastest record for the POVray-tracing benchmark. The off-the-shelf $150,000 cluster of Pentium II Xeons matched the performance of a $5.5 million Cray supercomputer."
