The green storage gap

Storage departments are trying energy-saving technologies, but measuring ROI is still a challenge. BEFORE THE GREEN movement--before the IT industry was consumed with data center footprint designs, creative cooling techniques and granular metrics like the number of watts per enclosure per I/O--Nick Daffan had a storage problem. Daffan, principal at Argus Information & Advisory Services LLC in White Plains, NY, watched his firm's storage needs skyrocket a few years ago. More customers, more reports and more precise computations were all fueling storage growth at Argus, which provides quantitative data to financial institutions for risk assessment and marketing purposes. Daffan would love to say that energy conservation topped his list of concerns when shopping for a new storage system. However, he admits, his primary motivation was less noble: His hardware lease was due to expire and his No. 1 priority when evaluating vendors was performance and how much the system cost, not power use. "It was before the energy crisis had spiked....

  • 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.
