Access "Dedupe and compression cut storage down to size"
This article is part of the Vol. 9 Num. 2 April 2010 issue of Primary storage dishes up dedupe
Data reduction technologies like data deduplication and compression have been well integrated into backup systems with impressive results. Now those benefits are available for primary storage data systems. Use less disk, save more electricity. What's not to like? If you buy the right products, you can pare down the disk capacity your data needs and maybe even cut your electric bills by as much as 50%. That's the promise of primary storage data reduction, and while slashing utility costs is appealing, there's still plenty of skepticism about the claimed benefits of the technology. While there's little dispute that this new class of products can reduce the amount of disk your primary storage uses, uncertainty remains about whether the gains outweigh the challenges of primary storage data reduction. The key questions about primary storage data reduction include the following: Why is it called "data reduction" rather than data deduplication? Disk is cheap. Why bother adding new technologies to reduce the size of the data it holds? What are the different types of... Access >>>

Data reduction technologies like data deduplication and compression have been well integrated into backup systems with impressive results. Now those benefits are available for primary storage data systems.
SRM tools struggle to meet today's demands
At one time, storage resource management (SRM) applications tried to be all things for all storage shops, with little success. Modern data storage environments require new tools to navigate the intricacies of virtualized environments, but the jury's still out on whether storage management vendors can meet those needs.

SAN consolidation with director-class switches
by Dennis Martin
A single director-class switch can replace multiple smaller switches while offering growth flexibility, high availability and a bevy of advanced features.
Tape may be teetering, but it's still a big part of backup ops
Tape no longer holds the place it once did in most firms' backup environments, but most storage shops still rely on it to some degree. Our Snapshot survey finds that while the vast majority of respondents use disk in backup, nearly 40% plan to buy tape gear this year.

Seeking clarity in the clouds
After you wade through the confusion that vendors have created, you'll find there are advantages to both public and private cloud offerings.
The solid state of storage efficiency
Storage managers want to use their storage systems more efficiently and vendors are finally forking over the tools to do it; but there may be a catch as vendors are faced with decreasing disk sales.
The modernization of backup: More disk, less tape
by Lauren Whitehouse
ESG's 2010 Data Protection Survey shows that the trend away from tape continues, with the economics of both deduplication, for disk-based backup, and cloud storage, for long-term retention, contributing to tape's decline.
