In 2001, Gold said the standard server used 100 watts of power. Today that figure has increased to 400.
"That's four times more power. Also there were only five servers per rack compared to 14 today," he added.
Brian Jarrett, an analyst with Enterprise Strategy Group, said while some of the EMC announcements are just "incremental" improvements in existing models, he took note of a new Disk Library tied to the Clariion CX3 UltraScale model.
The Disk Library backs up onto disk as many as 340P bytes of data. One petabyte is 10,000G bytes.
Jarrett said as enterprises collect more data, traditional tape backup, which occurs overnight when most offices are closed, may still be going on when workers return in the morning. Backing up onto a disk may be more expensive but can be done much more quickly.
EMC and other storage vendors are continually leapfrogging each other with new product announcements to remain competitive, Jarrett said.
EMC holds an industry-leading 20 percent market share in external disk storage, according to second-quarter 2006 figures from IDC.
It is followed closely by Hewlett-Packard with 19.3 percent. IBM has 13.2 percent, Hitachi 8 percent, Dell 7.8 percent and Sun Microsystems at 7.1 percent.
