Today on Toms' IT Pro:  The Benefits of Hierarchical Storage Management, The Silver Lining: Avoiding IaaS Tunnel Vision, IBM's Idea of the Next Era in Servers: "PureSystems", and more.

In her latest “Been There, Done That” article for Tom's IT Pro, columnist and contributor Laura Paoletti defines Hierarchical Storage Management and explains its benefits for IT shops. A subset of a group of storage strategies knows as Information Lifecycle Management, Hierarchical Storage Management implementation is a data storage system that automatically moves data between different tiered storage.

Basically, Hierarchical Storage Management systems store most of an enterprise's data on cheaper storage media, only moving data over to faster disk drives as needed. As Laura writes, the strategy, in effect, "turns the fast disk drives into caches for the slower mass storage devices."

She adds, the benefits of Hierarchical Storage Management is that it improves productivity and resource utilization, and finds ways to do more with what organizations already have on hand. It also provides enhanced access to resources and solves a number of problems for enterprises.

Also on Tom's IT Pro is the second post to Dan Sullivan's "The Sliver Lining" cloud computing blog. In it, Dan—an IT author, systems architect and consultant—explains how he believes software as a service (SaaS), not infrastructure as a service (IaaS) or platform as a service (PaaS), is today and will be tomorrow the most innovative and profitable segment of cloud computing.

Why? Because SaaS succeeds by adding substantially more value to a business process than IaaS or PaaS. The latter, for instance, aims to solve problems for developers,and there are few ways for IaaS providers to distinguish themselves in the market, at least compared to the other two cloud services.
