Sirius Computer Solutions held steady at No. 28 as its 2014 sales climbed to $1.4 billion up from $1.2 billion. The company has carried out two acquisitions in recent months, picking up virtualization and cloud solution provider Varrow in April and 60-person analytics firm Brightlight Consulting last October. Varrow provided Sirius with an increased presence on the East Coast and technical skills on VMware and Citrix, CEO Joe Mertens said. Sirius in April was named Cisco's Partner of the Year for the U.S. Central Region and earned a Cisco U.S. national award for architectural excellence in data center.
