Storage Management Strategies for the CIO
Access "Akorri advocates app analysis"
This article is part of the Vol. 5 No. 11 January 2007 issue of Comparing EMC Symmetrix DMX-3 vs. Hitachi Data Systems USP1100
Serial-attached SCSI (SAS) drives offer a higher level of performance vs. SATA drives, which have become ubiquitous in lower priced arrays. In recent months, several storage vendors have introduced arrays supporting both drive types, such as Gateway's E-842R SAN and EqualLogic's PS3000 Series. Andrew Monroe, IT manager at AirClic, a mobile information services company in Newtown, PA, says his storage consists of various types of databases all with different I/O patterns. He figured that moving from SATA to SAS drives would alleviate performance bottlenecks and the new EqualLogic SAS drives definitely improved performance, he says. Monroe admitted, however, that before using the PS3000 he didn't know exactly what type of performance improvement to expect. "We could only guess," he says. Monroe relies on Oracle tools to improve the performance of his databases. Akorri Networks, Littleton, MA, a new software development company just coming out of stealth mode, believes the most important performance metric "is how the application performs against its SLA [...

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.

Back to DR planning basics
by James Damoulakis
Business-impact analysis and planning is a necessary first step in preparing a disaster recovery plan. Without it, the likelihood of either overspending or coming up with an incomplete solution is highly probable.

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.
