The 2011 VAR500 is our annual ranking of the top VARs in North America, ranked by their solution-provider services revenue.

For this year's list, we took out the vendor services arms, except for stand-alone units; government contractors where systems integration was not a core part of their audience; and office product companies and e-tailers where services revenue wasn't distinguishable.

As a result, many companies moved up in the ranking this year; we also have more than 200 new companies joining the list.

On the following pages, you'll find profiles of the top 50 of this year's VAR500 companies.
