Cisco's recent announcement about unified computing caused some questions to be directed at the networking giant. Does it have new products? Why is Cisco talking now about virtualised data centers?

The company said: "There has been a lot of chatter about Cisco and unified computing and the data center/virtualization space...as well as what markets we are or are not entering. Our CTO, Padmasree Warrior, posted a blog on the topic of "unified computing" a few weeks ago and this blog entry is a follow-up to that post."
