Next What’s coming from R&D Tape Breakthrough A capacity leap means the storage medium is here for the long haul By Jim Utsler F or many organizations, especially larger ones, tape has long been an indispensable storage medium. But recent announcements about hard-disk-based data deduplication technologies have some considering moving away from tape altogether. IBM Fellow Evangelos Eleftheriou says that move may be premature, especially when it comes to archival data. This is particularly apparent now that IBM, in conjunction with Fijifilm, has announced a new record in magnetic-tape data areal density. Using a new barium ferrite (BaFe) technology and other storage advances, IBM Research and Fijifilm have shown that putting 29.5 billion bits per square inch on tape (or about 44 times the capacity of today’s IBM LTO* Generation 4 cartridge) is not only theoretically feasible—it’s been demonstrated. Th i s i s s ig n i f ica nt b e cau s e, according to Eleftheriou, tape is low cost, green and—as proven over many years—very reliable, particularly for data-retention purposes. In contrast, hard-disk drives (HDDs), as anyone who owns even a PC can attest to, are prone to mechanical failure. So any organization considering moving away from tape in 46 JUNE 2010 ibmsystemsmag.com/power ILLUSTRATION BY KEN EDMONDSON http://ibmsystemsmag.com/power
