SPEC is a non-profit organization that puts together benchmarks on a variety of products and services.  Currently they have a number of test areas:

• CPU
• Graphics / applications
• HPC / OMP
• Java Client / Server
• Mail Servers
• Network File System
• Power and Performance
• SIP
• Virtualization
• Web Servers

They obviously do not test every product on the market but it does provide some interesting results from major vendors (EMC, HP, IBM, SUN, etc.)
