The Framingham, Mass., company said data centers are becoming more utilized and therefore denser and hotter. The number of pieces of data center equipment is also slimming down to include fewer machines.
For example, with virtualization, customers can run multiple operating systems on one machine, reducing the number of machines they need to run their businesses.
Thanks to this push, customers concerned about using software to consolidate and automate their computer networks are interested in products from VMware, SWSoft, Xen and Virtual Iron.
Blade server systems are another prime example of the shift to more condensed data centers. Where mainframes once ruled the data center roost almost exclusively, smaller blades that slide in and out of chassis are becoming more prevalent these days.
Blades, which IDC said grew 49.3 percent as a market year over year and climbed 56.9 percent from 2004 to 2005, boast designs and redundant capabilities to allow one server to keep up and running after another winks out.
IT administrators can pull the dead blade out for repairs while hot pluggable systems don't miss a beat to server computing power to computers.
