Monolithic going modular

Once hard-and-fast product categories, the lines that separate monolithic from modular storage are getting increasingly blurry. Not only are modular systems getting bigger, faster and more capable, but newer monolithic systems are taking their cues from more flexible, configurable midrange systems. The term "monolithic" usually applies to systems like EMC's Symmetrix, Hitachi Data Systems' Lightning and IBM's DS8000. These are high-end systems that have traditionally required customers to buy all the infrastructure they'll need up front, including the I/O controllers, the cache and even the frames; the only thing you could buy over time was additional disk drives. That doesn't sit well with users who like the idea of being able to buy performance and capacity as they go. "Our customers have told us that they want to match their initial purchase to what they need and grow it only as needed," says Craig Butler, manager of IBM's TotalStorage disk solutions. IBM responded to that request last fall with the introduction of the DS6000...

  • Bridging the gap

    Many disaster recovery and remote backup programs rely on an efficient, cost-effective WAN. Fiber-optic network technology is often required for long-distance data transmission, but you need to know what transport is best and the related implementation issues.

  • DR testing infrequent at best

    Have you tested your DR plan?

  • Storage for manufacturing

    Manufacturing environments typically have different storage requirements than corporate apps, and have to deal with globally dispersed design teams as well as growing regulatory concerns. Here's how several prominent manufacturers have met the challenge.

  • New tools to classify data

    by  Brad O'Neill

    Putting data on storage systems appropriate to its value requires the ability to classify data. An emerging category of applications, Information Classification and Management apps, can index enterprise information and execute precise actions based on its content.
