About this survey: Our survey was conducted in August 2004 by e-mail.

Storage managers are continuing down the paths they indicated last March, if a little more cautiously, and those paths are leading toward a tiered environment (see "Green light for disk spending," in the May issue).

Modern storage arrays offer disk types to meet any need -- costly Fibre Channel (FC) disks for high-end applications requiring superior performance and availability, and lower-priced SATA disks for less-critical data. The arrays also come with mixed RAID configurations. But selecting the right mix of disks and RAID levels requires understanding the impact of those decisions.
