Hitachi LTD has announced a 1 TB disk drive due out by 2007 that will feature perpendicular recording as a method for surmounting the limitations imposed on areal density by superparamagnetism. Perpendicular recording aligns magnetic fields perpendicularly to media rather than in parallel, enabling bits to be squeezed more closely together without interfering with magnetic fields.

Data DNA

Effective storage design begins with an understanding of the data that is to be hosted: the access, speeds and feeds, security and other requirements posed by the application and the business process that is being served.

Hosting Reqs

Data inherits its hosting requirements like so much DNA from business processes and applications. Platform resources and services should be defined only after requirements are fully understood. One size fits most architecture never fits anyone's data well!

SRM is Key

Containing costs and allocating storage capacity efficiently requires Storage Resource Management. You should prefer an SRM solution that gives you an application-centric view of storage infrastructure to ease troubleshooting. Standardize on an SRM product, then only buy platforms that can be managed with that product.

Plumbing

Storage "plumbing" alternatives are in no short supply. Every option has its value, and the right plumbing is the one that supports the data movement and access requirements that you are expecting. Choose wisely.

Platforms

Eschew marketecture. Everyone in the storage industry is selling a box of hard disks. "Value add" software is a cost accelerator. Why not purpose-build storage to obtain exactly the right mix of capacity, performance and functionality that your data really needs? Consider placing value add functions into the network as shared services, not as proprietary on-array functions.

5 Myths of Distributed SRM

On February 10 at CA's Los Angeles offices, site editor Jon Toigo and CA consulting specialist Scott Howie presented their views of the continuing story of storage resource management in the distributed world. Now more than ever, Toigo argued, companies need to instrument their storage infrastructure for storage management. Toigo prefers the eventual integration of purpose-built storage platforms and services mounted on routers and gateways in a network (as opposed to being embedded on an array controller)via W3C Web Services standards. Until we get there, selecting and deploying a solid SRM product is our only and best hope for reigning in the Wild West of storage. Howie continued the theme with a discussion of CA's tools for managing storage.
