Next year will see Cisco deliver a "Big Bang" in switching, blade servers for the data center, high-definition TelePresence conferencing for the home, and a security plan for virtualized and cloud computing environments.

Cisco's switching upgrade will emerge in January and encompass more than just the Catalyst 6500, as initially expected. The emphasis on Big Bang, the code name for the switching upgrade, will be green and apply to Cisco's entire switching portfolio, says Marie Hattar, vice president of network systems and security solutions at Cisco.

"It's an evolutionary capability. It's not a new platform," Hattar said at Cisco's CScape analyst conference recently. "It's really more tied to green capabilities, and how the network really enables those types of capabilities."

Hattar would not divulge any further details on Big Bang, other than to say it will emerge in late January.

Hattar was also tight-lipped on Cisco's intentions in the blade server market. Cisco is reportedly developing a blade server offering, expected in 2009, that will ostensibly compete with IBM, HP and Dell systems deployed for years within data centers.

IBM and HP have been longtime partners of Cisco's, but observers believe those relationships will be strained if Cisco offers its own blade server system.

Analysts say Cisco's data center ambitions will accelerate in 2009 and underscore the company's intentions to become more of an overall IT vendor.

"Can they really make the credible transition to an IT vendor from a networking vendor?" asks Zeus Kerravala of The Yankee Group. "That is their absolute biggest challenge because that gets them into a whole different set of buying criteria."

Adds Rob Whiteley of Forrester Research: "The data center is probably going to be the most interesting battle ground (for Cisco). Whatever comes out in 2009 from Cisco is going to be very virtualization-centric."

Also on tap for 2009 from Cisco is a TelePresence virtual conferencing system for the home; and language translation and speech recognition for Cisco's new MXE 3000 media processor, which debuted in early December. The home TelePresence systems will go into trials in the summer and be generally available sometime after that, says Marthin DeBeer, senior vice president and general manager of Cisco's Emerging Technologies group.
