There was a time not too long ago when hard drive capacities were measured in megabytes. Now, even small-business hardware can be scaled to hold more than a terabyte — 1024 gigabytes — of data. Does any company need that much storage? The answer is an unequivocal yes.

The amount of information produced each year is skyrocketing. According to the Enterprise Strategy Group, companies are seeing a 90 percent annual growth rate for e-mail, reports and presentations. In other words, every message, every PowerPoint ﬁ le and every document produced by every employee in an organization is being stored somewhere, and the bulk is nearly doubling every year.

Large businesses store data on tape drives and hard drives, both in servers and backup repositories. Depending on the size of the operation, the amount of data and the speed with which personnel needs to access the data, storage costs can be considerable. Trends A recent CIO Insight report by Jeffrey Rothfeder (May 2006) pointed out that many companies are realizing that they can no longer beneﬁ t sufﬁ ciently from the vast amount of information they maintain.

THE STORY CITES RESEARCH COAUTHORED BY ECONOMIST HAL VARIAN, A PROFESSOR AT THE UNIVERSITY OF CALIFORNIA–BERKELEY’S HAAS SCHOOL OF BUSINESS, WHO FOUND THAT COMPUTER USERS PRODUCED FIVE EXABYTES OF NEW INFORMATION IN 2002, TWICE THE AMOUNT CREATED JUST TWO YEARS EARLIER.

(Five exabytes is roughly equivalent to the information that would be contained in a half-million new libraries the size of the print collection at the Library of Congress.) About 92 percent of this new information is stored in magnetic media, primarily hard disks.

How can companies gain control over that kind of information overload? And how can they ensure that older data is stored and protected appropriately while new information is kept closer to “Our ability to store and communicate information has the ”surface“ but also protected? far outpaced our ability to search, retrieve and present it. Information management may turn out to be one of “Information governance programs,” Rothfeder writes, “are an attempt to corral all of this information into a useable form, the major challenges of the new century.” an ambition that so far has eluded most organizations.” — Hal Varian, economist, University of California

Integration The best way to derive the most beneﬁ t from revamping storage systems and deploying an ILM scheme is to ensure that your data center is fully integrated with other cutting-edge solutions.

Speciﬁ cally, you’ll want to ensure that network switches are tightly coupled with new servers to ensure optimized performance. Many backup and monitoring products are designed to ﬁ t directly into server racks and blade chassis, so you can leverage the space-saving and management ease already built into the hardware and use the accessory devices to support entire stacks.

In addition, security products — either software or appliances — and uninterruptible power supplies (UPSs) are also crucial to maintaining “ ILM WON’T TELL YOU WHAT DATA TO RETAIN FOR REGULATORY the integrity of your data storage.
