Storage arrays: Practical guide to buying and implementing

Storage arrays can bring huge storage capacities to a data center. Critical corporate data is protected by allocating some array disks for RAID tasks, and tiered storage matches drive cost, reliability, and performance against the value of corporate data. But the choice of storage array is not easy. Capacity and performance are still the most obvious considerations, but lower-end systems are rapidly expanding to include high-end features. When it's time to upgrade an array, or add another system to the data center, some advance planning can significantly ease your acquisition and integration issues.

Storage arrays can bring huge storage capacities to a data center. Critical corporate data is protected by allocating some array disks for RAID tasks, and tiered storage matches drive cost, reliability and performance against the value of corporate data. But choosing a storage array is not easy. Capacity and performance are still the most obvious considerations, but lower-end systems are rapidly expanding to include high-end features. "You now have [mid-tier] arrays with over 400 disk drives on them, so you can gave raw capacities in the hundreds of TB," says Greg Schulz, senior analyst at Evaluator Group. "Almost every mid-range array now supports controller-based copy, snapshots, and remote mirroring and replication (just like the big mainframe storage devices)." If it's time to upgrade an array or add another system to the data center, this article offers some tips to help you make the right purchasing decisions, covers the most important guidelines for a successful implementation and shows you the most popular storage array product (as voted by actual storage users).
