Access "Quality Awards II: Leading libraries"
This article is part of the Vol. 5 No. 11 January 2007 issue of Comparing EMC Symmetrix DMX-3 vs. Hitachi Data Systems USP1100
The second edition of the Diogenes Labs-Storage magazine Quality Awards for tape libraries largely reinforced the results of last year's survey. More than any other products in the data center, tape libraries are under assault. Disk-to-disk backup and continuous data protection (CDP) products promise to reduce a company's reliance on tape backup. With all of the focus on eliminating tape, one would assume that users are unhappy with their tape products. But that assumption would be off-base considering the results of the Diogenes Labs-Storage magazine 2006 Quality Awards survey of tape library users. Almost across the board, the 385 Storage readers who provided more than 500 product evaluations indicated a degree of satisfaction consistent with that of our disk array surveys (see "About the survey"). Users apparently have a high degree of brand loyalty, too, as only 9% of respondents say they own libraries from three or more vendors. User satisfaction is further confirmed by the fact that 80% of respondents say they would buy the same system again if they ... Access >>>

Quality Awards II: Leading libraries
Although they're the most mechanical part of a backup system, users are fairly satisfied with the reliability of their tape libraries. And despite high-profile consolidation among tape library vendors, the results of the second edition of the Diogenes Labs-Storage magazine Quality Awards largely reinforced last year's results.

Face-Off: EMC DMX-3 vs. Hitachi USP1100
Only a handful of storage vendors produce truly top-of-the-line arrays, and EMC and Hitachi Data Systems dominate those ranks with their respective Symmetrix DMX-3 and TagmaStore USP1100 products. These vendors attain high capacity and high performance using two very different architectures. We examine the differences to see if one approach outstrips the other.

Protect remote-office data
Centralizing remote-office and branch-office (ROBO) apps and their data in the primary data center has enormous economies of scale. These remote-data apps cut the amount of data sent over the wire, making it possible to economically back up remote data to a central site. We provide a sampling of the various ROBO data management products on the market, and describe how they can best be implemented.

Storage virtualization technologies have been purchased and implemented successfully for years
Storage Bin: Storage virtualization technologies have been purchased and implemented successfully for years. The rest of the IT infrastructure must try to catch up and, ultimately, the only thing not virtualized within the data center will be the last guy standing.
