Access "Users want more from tiered storage"
This article is part of the Vol. 5 No. 10 December 2006 issue of The hottest storage technology for 2007
Storage vendors are building block-based tiered storage into their products, but some users are asking why the combination of block-level granularity and file-level automation isn't a part of large, high-end, heterogeneous tiered storage systems. "Tiering data for performance management is a struggle when it crosses the bounds of a controller," says Jeff Boles, IT manager for the City of Mesa, AZ. "Block-level data in and of itself is never going to be completely indicative of access patterns because that's not the way we work." Vendors say products simply don't exist today that could keep a single block within a larger file on primary storage while sending the rest of the file, block by block, to a separate file system on a separate physical tier, bringing the blocks back together when different parts of the file are accessed again. Midrange arrays like Compellent Technologies' Storage Center SAN and EqualLogic's PS Series have begun baking in block-level, tiered storage functions and nearly every high-end storage vendor offers a product that will ...

SAN consolidation strategies
As islands of SANs proliferate in companies, the cost of storage can soar. Sound SAN design strategies allow companies to reduce the number of SAN islands, strengthen a primary SAN, make storage easier to manage and provide more data protection.
Configuring storage for ERP
The "crown jewels" of corporate data are typically maintained within enterprise resource planning (ERP) applications. But for many storage managers, ERP is a minefield of critical information and competing priorities. In this first installment of a three-part series, we look at ways to protect ERP data while improving performance.

Hot technologies for 2007
"Storage" magazine's editors reviewed technology developments, product introductions and storage standards to come up with this short list of must-have technologies for 2007. We believe iSCSI SANs, hardware-based tape encryption, high-capacity disk drives, virtualization and thin provisioning will have the greatest impact on enterprise storage environments.

- Mobile drive tech could move into data center
There are three distinct architectures of host-level replication software: Windows-only file system, multi-OS file system and multi-OS blocklevel products. Each alternative offers specific features that make it a better fit for some types of data protection.

Data backup versus data archiving
Companies should split backup and archiving into two separate initiatives to help them differentiate between copying data for recovery, and retaining data for future reference and retrieval.
Is it really a disaster?
Was it really a disaster after all? It's important to distinguish operational recovery from disaster recovery because the tools and techniques used in each situation can differ significantly.
