Abstract:
1. A server system comprising: a high performance spinning-type hard drive for storing data; and a power controlled spinning-type hard drive for storing data, wherein an entirety of the power controlled spinning-type hard drive is configured for lower power consumption as compared to the high performance spinning-type hard drive; and a policy manager that assesses multiple metadata analysis of a data set to be stored into one of the high performance hard drive or the power controlled hard drive, the multiple metadata analysis including all of, (a) an analysis of usage rate metadata of the data set to be stored, (b) an analysis of content type metadata of the data set to be stored, and (c) an analysis of owner and consumer metadata of the data set to be stored, wherein the policy manager receives the multiple metadata analysis of (a), (b), and (c) and makes a determination whether the data set is to be stored in the high performance hard drive or in the low power hard drive, the determination based on rules to eliminate contention between the multiple metadata analysis, the policy manager implementing rules of an application policy and a file system policy, the application policy defining power management directives within an application, and the file system policy including rules associated with a file system; wherein the data set to be stored is placed on the power controlled spinning-type hard drive after classification of the data into the characteristics of a fully distinguished file name, creator, owner, consumer, distribution lists, access control list detail, certificates, signature attributes, protocols, content resolution, encoding technique, encryption technique, key properties, internal subjects, keywords, content tags, assemblies, associations to other files, replication, caching, directory and related database extensible properties.
