Solid-state distinctions emerge

  AS SOLID-STATE STORAGE enters its adolescence, the technology is still trying to find its place in the storage food chain. Solid state, or flash, is becoming more familiar and widely available as it continues to develop into distinct market segments, but questions remain about power consumption, performance and the best uses for solid-state drives (SSDs). Framingham, MA-based IDC tried to quantify some of the uncertainty in a recent benchmarking report that compared SSDs, hard disk drives (HDDs) and hybrid drives using a laptop PC. Dave Reinsel, lead author of the report and group VP of storage and semiconductor research at IDC, says they found that drive performance can vary greatly from device to system level. "The system can act as a great equalizer and diminish some of the benefits that you might have seen at the device level," he says. IDC's report also concluded that SSD and hybrid technology use will continue to grow, and that SSD controllers will be a key piece of further development. As SSDs mature, key differences ...

  • Are solid-state disks ready for the enterprise?

  • Green spin cycle

  • Second-generation CDP

    Continuous data protection (CDP) received lots of attention but garnered few takers as a standalone product. Since then, the technology has been incorporated into data protection products and its role is now likely to expand. In addition, rapid data growth and shrinking backup windows are two of the trends that support the increased adoption of CDP.

  • Solid-state distinctions emerge

  • Economy and capacity at odds

    With fewer bucks in the budget, storage managers are facing some constraints in dealing with growing storage capacities. But, according to Storage magazine's Purchasing Intentions survey, they're responding by earmarking some of those dollars to newer technologies like data deduplication that will help them cope with burgeoning data stores.

  • The green storage gap

    by  Ellen O'Brien

    Storage departments are trying energy-saving technologies, but measuring ROI is still a challenge. Some storage administrators are plugging vendor-supplied product power consumption numbers into so-called green calculators, but it's no easy task as there are inconsistencies in how each vendor presents its product's power requirements.

  • Storage for high-performance computing

    by  Deni Connor

    The storage and server cluster installed at The University of Texas at Austin is a lesson in how to do high-performance computing (HPC). Storage requirements for HPC go beyond massive capacity and include the use of high-performance file systems.

  • Ask the Experts

    Where and when should we use data dedupe for remote-office backups?

  • Best Practices: Why you can't go it alone

    by  Ashish Nadkarni

    Most IT departments are split into islands of expertise, like storage, servers and networks. But the time is coming when those disparate groups will have to learn to work together. Network consolidation is just one of the technologies forcing storage pros to build stronger interdisciplinary IT teams.
