4. Cisco Begins To Muscle In On HP's Server Dominance

Cisco, which entered the server business only 2.5 years ago, this Spring finally broke into the list of top five server vendors in North America thanks to its surge in blade server sales.

By year-end, Cisco had leapt over Dell to become the number three blade server vendor with a 10.7-percent market share, according to IDC.

Growth should continue for Cisco as it is expanding its UCS (Unified Computing System) from a focus on VMware virtualization to embrace Microsoft's Hyper-V.
