Access "Monolithic going modular"
This article is part of the Vol. 4 No. 6 August 2005 issue of The best high-end storage arrays of 2005
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 system, a companion to the ... Access >>>
