Method of thinking effective information application of actualizing efficient storage investment information (the electronic data) according to the change criticality and utilization intended frequency and the like, as needed, by moving & arranges to the storage which is suited for housing that. When management of the data and the storage which you follow this (technique), or the solution which supports that management is said, it is.
As for the information inside enterprise being utilized & being accumulated character differs respectively, "" both renewal perusal those renewal which are done frequently "are little, but as for perusal many ones" "it is not almost referred to, but those where retention is required legally" and so on it is various. Furthermore value and use of such information always change with time lapse and environmental change etc..
On the other hand, also the storage device "HDD" "removable disk media" "tape" and so on being various, capacity and data rate, price, there is various qualities in the aspect of reliability and long-term storage aptitude etc..
Then, method of thinking was born in the aspect of cost and service level in the appropriate storage device, of optimizing both parties of information application and storage investment by the fact that it moves & arranges the data life cycle of information (the compilation formation, open and perusal distribution and retention archive and abolition deletion) according to.
As a concrete example of management process, quite being important, the high reliability high performance storage of the high end with it manages the information whose also utilization frequency is high (disk array, and the like), small-to-medium-sized scale storage (HDD and the like) it uses the kind of information which is utilized with general office work, there are no times when it renews excessively the data whose it is important to keep, storage of cost retains low (the tape and the like), the information which has become unnecessary becomes something which is cancelled.
The word, ILM, storage technology and EMC etc. of the American major storage manufacturer being something which you lecture as part of the respective company strategy from around 2002, appeared as a concept of the next generation storage solution, but there is also the movement of obligation such as retention, protection and abolition etc. of the data with various law systems, recentlyit attractsattention as a compliance solution.
As the ILM solution which each bender offers from simple ones such as management of centralization of storage, following to the application of the data, draws up rule and policy, houses the data on the basis of this, copies, backs up and archive etc. automatically, it is opposite to the direction which integrates indexing and search and such as the removalof the data the contentsmanagement etc. for the data and the file.
Furthermore monitoring of utilization circumstance of the data and storage, study (making intelligent), is done match to judgement and such as service level guarantee of storage constitution.
