Five Storage Strategies That Can Save You Cash

Network World — Storage costs eat up at least 11% of IT hardware budgets, but there are plenty of ways to save money without sacrificing performance or security. In a new report called "Five Key Storage Strategies for a Down Economy," Forrester analyst Andrew Reichman provides a road map for smart purchasing and maximizing the resources you already have. Here's a summary.
But as the economy gets worse, "storage vendors will be trying even harder to win new deals and protect their existing accounts from competitors trying to do the same thing," Reichman writes. "Use this situation to your advantage by introducing a fresh sense of competition among the vendors you work with." By undertaking a request for proposals bidding process, you can win discounts from your current vendor or discover a new, less-expensive vendor you weren't aware of.
2. Avoid new purchases by reclaiming what you have. Wasted storage, not surprisingly, is a waste of money. Storage is allocated but not used all the time for many reasons. "Some applications and operating systems don't lend themselves to gradual storage expansion over time; they require a large up-front allocation that may or may not be consumed eventually," Reichman writes. "This tendency for over-allocation combined with limited ability to effectively forecast data growth in most organizations leads to a significant gap in the amount of capacity that is allocated versus actually used."
Reclaiming wasted storage will often require application downtime, making careful planning necessary. Using storage virtualization is one way to migrate without disruption.
Other examples of wasted storage include: servers that have been taken off-line without its associated storage being returned to the free pool, and storage that's "'mapped but not masked,' meaning it has been allocated within the storage array but not recognized by a server."
3. Audit backup and replication configurations to cut waste. As important as disaster recovery is, the technologies that enable it sometimes lead to waste. "In a typical storage environment, there can often be as many as 10 copies of the same data -- several days of full backups, a couple of snapshots, and a fully replicated copy at the alternative site," Reichman notes. "Most backup systems have inadequate reporting capabilities, so it's difficult for storage administrators to associate applications to their backup jobs and their retention schedules."
