It defines its approach as managing the creation, protection, migration, archiving and ultimate disposal of data, managing data migration as it passes from state to state throughout its lifecycle.\u00a0HP's data management announcement last week (see link below) focused on its ability to deliver cradle-to-grave solutions applying to data retention, data management, and the management of reference information. More than that however, HP addressed the importance to ILM of managing more than storage alone, and pointed to its historical competence of managing across the enterprise.\u00a0What does this mean for you? Both companies have in fact been providing various aspects of ILM for several years now, so at this point the significance of the announcements has less to do with technology and much more to do with defining a marketing direction.\u00a0 EMC will get some useful mileage out of its Legato acquisition, and HP is sure to benefit from the intellectual property it produces as it continues to roll our its Adaptive Infrastructure initiative.\u00a0 How all of this is implemented will of course be the key.While neither company has all the technology it needs to deliver full-blown ILM solutions at this time, these announcements are good indicators of where a large chunk of their R&D investment will be going. It is abundantly clear that the degree to which these and other vendors can automate and integrate their various solutions will play a major part in defining their success.Of course EMC and HP aren't the only vendors working on and delivering pieces of an ILM solution. Several of their competitors (StorageTek and Outer Bay come to mind, but there are many others as well) also provide ILM technology. IBM, with its history in hierarchical storage management\u00a0 and its investment in autonomic computing is sure to join in the mix in the very near future.\u00a0 Sun and Veritas are likely to weigh in on this as well.
