  • Utility storage: Ready for a long haul?

    First will come virtualization, then utility storage. That's long been the vision of how enterprise storage will evolve as IT grows increasingly dynamic and on-demand becomes business as usual.

  • Can your network handle HD video?

    Consider this: In the week following September 11, 2001, your users were glued to their television sets tracking breaking news. If an event of similar proportions happened today, they would expect the enterprise network to be able to handle not only real-time video feeds but also high-definition videoconferences and surveillance, as well as instant access to social-networking tools.

  • Beware videoconferencing pitfalls

    With the rise in adoption and availability of enterprise videoconferencing systems comes a warning from IT pioneers: Thinking this technology is simply plug-and-play will lead to disaster.

  • On the horizon: 100 Gigabit Ethernet

    The IEEE's latest project could significantly boost the speed of traffic delivery across the Internet. In November, the IEEE's 802.3 Higher Speed Study Group announced that it's working to create a 100Gbps Ethernet standard, which could be ready by 2010. The group is racing against time to accommodate the increasing demands of content creators and consumers around the world. Sandra Gittlen recently spoke with John D'Ambrosia, chairman of the study group and a scientist at Force10 Networks, about the impact of 100G Ethernet on technology users.

  • Gigabit Ethernet standard is here
