For these projects, particularly the CERN experiments whose members number in the thousands and whose data collections are expected to reach 100 Petabytes
early in the next decade, the computing resources available through the iVDGL are expected to enable new classes of data-intensive algorithms that will lead to new scientific results.
During the January to March period this year, Globe registered a 37 percent increase in data traffic to 181 petabytes
from 131 petabytes
in the same period last year.
A terabyte is equivalent to 200 hours of music, while a petabyte
is about 280,000 hours, or nearly 32 years of music.
IBM is working on a 120PB (petabyte
) drive, which quite definitely is the largest we've ever heard of.
For the latter, IBM said that researchers are using an unspecified magnetic technology that could store a petabyte
of data in a standard 1U rack unit.
One kilobyte equals 1,000 bytes; one megabyte is 1,000 kilobytes (1 million bytes); one gigabyte is 1,000 megabytes (1 billion bytes); one terabyte is 1,000 gigabytes (1 trillion bytes); one petabyte
is 1,000 terabytes (1 quadrillion bytes).
Johns Hopkins University cosmologist Alex Szalay and Jim Gray of Microsoft, who was lost at sea in 2007, spent much of the past decade discussing challenges posed by data files that will soon approach the petabyte
([10.sup.15]--or quadrillion--byte) scale.
Their GridWorks storage resource management platform, coupled with McDATA SANavigator, monitors more than a petabyte
of customer data across approximately 1,500 companies, dozens of SANs and thousands of servers to assist clients in protecting their data and managing their resource management objectives.
is equal to about 3.4 years of 24/7 full high-definition video recording.
Fujitsu said it is enabling enterprises to push beyond the boundaries of unpredictable data growth into the double-digit petabyte
range, with the introduction of the new FUJITSU Storage ETERNUS DX8700 S3 and DX8900 S3.
