Tiering, ILM, HSM and WGAF

In 2004, SNIA defined Information Lifecycle Management (ILM) as comprising the policies, processes, practices, and tools used to align the business value of information with the most appropriate and cost effective IT infrastructure (I would have added 'for its placement' but the ILMers at SNIA are wicked fussy about inferring that ILM has ANYTHING to do with storage. –Ed.) from the time information is conceived through its final disposition. Information is aligned with business processes through management policies and service levels associated with applications, metadata, information, and data.
