Access "A closer look at thin provisioning"
This article is part of the Vol. 6 No. 5 July 2007 issue of Benefits of third-party data protection and recovery management tools
Everyone wants a slice of thin provisioning. Hitachi Data Systems (HDS) and EqualLogic recently added the technology to their arsenals, prompting EMC to confirm its plans to support thin provisioning in early 2008. Hewlett-Packard (HP) is rumored to have something in the works for this summer, and IBM has talked about thin provisioning in the context of its System Storage SAN Volume Controller (SVC) software. Industry analysts expect thin provisioning to be available on all midrange and high-end arrays by mid-2008. Thin provisioning lets administrators earmark more capacity than has been physically installed on an array to delay storage purchases until absolutely necessary. Physical capacity is only dedicated when an application writes data, rather than when the storage volume is initially allocated. 3PAR and Compellent Technologies have long been offering this feature and many of their customers swear by it. "We no longer have to guess how much storage we need; we can pre-allocate and when we get up to or close to that amount, we just add more," says Curtis... Access >>>

HDS reigns over enterprise arrays ... again
The third annual Diogenes Labs-Storage magazine Quality Award for enterprise arrays saw some changes among the vendors, but a familiar theme prevailed as Hitachi Data Systems copped top honors for the third time.
Tools to fine-tune your backups
Backup and recovery applications typically include reporting capabilities, but they're often rudimentary and provide only basic information on the success or failure of data protection operations. Data protection and recovery management (DPRM) products, an emerging class of monitoring and planning tools, fill in the gaps where traditional backup apps fall short. DPRM tools provide advanced capacity reporting, predict usage patterns and allow performance tuning, troubleshooting and cost management. Here's how to pick the best product for your shop.

Mix SAS/SATA drives for speed or capacity
by Jerome Wendt
The emerging class of mixed SAS and SATA storage systems could be the next big disruptive technology. Mixing high- and low-cost SAS and SATA disk drives within the same system, at interconnect speeds comparable to Fibre Channel, is a recipe for significant change and opens the door to data lifecycle management.

Can iSCSI crack the enterprise?
by Stephen Foskett
iSCSI storage systems are showing up in medium-sized businesses, but storage managers at large enterprise shops have been reluctant to embrace them. This is largely because Fibre Channel (FC) is so firmly entrenched in bigger companies. But iSCSI offers some unique benefits that may appeal to shops with FC-only environments.

Best Practices: The ultimate archiving challenge
Given current practices, it's questionable whether electronic information created and stored today will be usable 10 years or 15 years from now. The steps we take now will greatly affect the magnitude of the problem facing us (or our successors) in the future.
Storage Bin: Boring is good
by Steve Duplessie
They may not be the sexy new technologies of the moment, but boring "vision" tools that provide insight and report on storage infrastructure are as necessary to your environment as ensuring that the system you run is getting power from the wall.
Hot Spots: The inevitability of tape encryption
by Jon Oltsik
In the near future, encryption technologies will closely mirror the old "death and taxes" cliché as one of those things that are inevitable. Approximately 25% of enterprises have gotten the encryption message, but the vast majority are still on the sidelines.
