Allocating storage workloads

By Linda Gail Christie

Industry benchmarks reveal that storage workloads vary considerably based on workload types: business processing, Internet applications, technical applications, collaborative applications, decision support, or infrastructure maintenance, for example.

"Business processing -- the real-time operations that involve large amounts of data, high read-to-write ratios, and maintaining high levels of integrity -- will require more people: One person per gigabyte or even per one-half gigabyte," said David Floyer, VP of research for ITCentrix, a developer of innovative IT decision support solutions. "Financial institutions will have at least a 25 percent higher overhead because of more stringent backup and integrity requirements. Integrity in this environment is much more important because if you lose a piece of data you may have to roll back thousands of transactions taking hours to get back online. It's headline news if they lose data."

"This is in contrast to a technical organization managing fewer and larger files, CAD/CAM, for example, where one administrator may be able to manage several gigabytes," said Floyer. "In this environment, it's rather easy to back up to replace a lost or corrupted file."
