Access "Flash storage settles in high-performance niche"
This article is part of the Vol. 5 No. 5 July 2006 issue of Lessons learned from creating and managing a scalable SAN
YOU NEED ONLY look at the tiny 4GB USB flash drive dangling from your keychain to realize that there are some real alternatives to current disk-based storage. Indeed, there are a number of efforts underway that tap into solid-state technology to create nonvolatile alternatives to magnetic disks. The result is high-speed storage that barely sips power and runs cooler than anything that's ever set foot in a data center. Solid-state disk (SSD), or flash, also costs a lot, especially when compared to spinning disk. So while these new storage technologies are ready for prime time in consumer and mobile gadgets, they aren't likely to show up in any significant numbers in data centers very soon. Still, some have carved out niches and made some inroads, handling mostly high-performance, ultra-mission-critical apps. Texas Memory Systems' RamSan-400 uses SSD technology to provide up to 128GB of extremely high-performance storage. Compared to the 500GB and 750GB disks offered by traditional storage vendors, 128GB may seem paltry. But the RamSan-400 isn't ... Access >>>

Cut data down to size
by Arun Taneja
With today's extreme data growth rates, adding disk-based protection is no longer an option but a requisite. Data reduction can help ease growth pains by paring down the data that goes to disk. There are many products with data-reduction capabilities available, but the technologies they use vary widely.

Backup apps: More choices beyond the big three
With numerous applications and a variety of hardware and software platforms, a single enterprise backup software product may not suffice for many companies. A bevy of backup applications that aren't as well-known as "the big three" may be better architected to handle new requirements.
