ILM: Panacea or Proprietary Poison?: Page 7 of 24

HP offers no technology for data-naming or access-frequency counting, or for storage-platform characterization by cost or capability. Instead, it claims to focus "on the business metrics that identify the areas of IT where we can offer a significant reduction in total cost of ownership."

The vendor declined to give us specific pricing information, explaining that the cost of any ILM solution will depend on the components and services selected.

    As HDS sees it, ILM and DLM are distinct from each other, yet complementary. The vendor defines ILM as "the function(s) necessary to manage information through the work flow or business process from creation of an information object to its completed state. ... ILM typically exists at the application layer and is most often associated with document/content management and collaboration software, such as Documentum, FileNet and Open Text." HDS characterizes DLM as "the function(s) necessary to manage a data object or collection of objects within the storage environment based on the prescribed value or access requirements associated with the life cycle of the data object."
