Information Life Cycle Management

Understanding what happens to data throughout its lifetime is becoming an increasingly important aspect of effective data management. What happens to data as it ages? Does usage decline as data ages? Does the value of data increase or decrease as it ages? Why are we keeping more data longer than ever before? What conditions indicate when data should be retired? Do storage management requirements change as data goes through its life cycle? If data is the most valuable asset of so many businesses, why do we know so little about it? Why doesn’t anyone consider their non-digital information as part of their Information Life Cycle Management (ILM) strategy? These important questions need answers so we can understand how data should be managed and where data should—ideally—reside during its existence.

zHoliday Storage Spirit

From FICON to fabric and “virtualization” to the many “natural” and manmade events that show disaster recovery in action, what a year it has been!

So, what’s on your wish list this year? More storage, disk, or tape? There’s connectivity and interfaces for FICON and more switch and director ports. How about we dust off last year’s plan and finally put in that SAN? What about LANs, MANs, WANs, SANs, POTs (pretty old technology) and PANs (pretty amazing new stuff)? Is this real or part of the “virtual” storage land?…

Has Open Storage For zSeries Finally Arrived?

What’s old yet new, black and not blue, supports Linux, FICON, and open storage interfaces, too? Well that would be an IBM zSeries mainframe. I recently saw an interesting cartoon that showed Unix being squeezed out by Windows and Linux environments. Also in this cartoon were the banners of other ousted systems and technologies, including mainframes. While Unix was long hailed as the operating system that would put the final nail into the mainframe’s coffin, it is clear that the zSeries processor family is very much alive as are z/OS and Linux. This article examines how various open interfaces and technologies coexist and are part of a zSeries environment today that is very much alive…
