A system and method for an e-mail rating system, where e-mail senders are evaluated based upon past performance. When an individual receives an email message and determines it to be SPAM, they notify a central database, repository or server. This central server, known as a Span Detection Server or SDS, maintains a list of e-mail senders and their associated spam rating. Spam thresholds are applied to incoming e-mail by a spam filter in conjunction with the SDS. Depending upon the sender's rating as compared to these thresholds, a received message is classified as desirable, undesirable or conditional.

The intelligent data storage manager functions to combine the non-homogeneous physical devices contained in a data storage subsystem to create a logical device with new and unique quality of service characteristics that satisfy the criteria for the policies appropriate for the present data object. In particular, if there is presently no logical device that is appropriate for use in storing the present data object, the intelligent data storage manager defines a new logical device using existing physical and/or logical device definitions as component building blocks to provide the appropriate characteristics to satisfy the policy requirements. The intelligent data storage manager uses weighted values that are assigned to each of the presently defined logical devices to produce a best fit solution to the requested policies in an n-dimensional best fit matching algorithm. The resulting logical device definition is then implemented by dynamically interconnecting the logical devices that were used as the components of the newly defined logical device to store the data object.

Intelligent data storage manager

An intelligent data storage manager is operational in a virtual data storage system that uses a storage element to store data for a host processor. The storage manager includes a host interface and a controller. The host interface receives a virtual volume having virtual blocks from a host processor. The controller sequentially segments the virtual volume into data pages. Each data page includes virtual blocks of the virtual volume. The controller generates a meta data page associated with the virtual volume to map the data pages to the virtual blocks of the virtual volume. The controller uses the meta data page to selectively store the data pages onto the storage element. The storage element has a partitioning configuration and the amount of the virtual blocks included by each data page is a function of the partitioning configuration of the storage element. The meta data page associated with the virtual volume includes meta data page records. Each meta data page record includes meta data records and each of the meta data records corresponds to at least one virtual block. The storage element includes high and low performance storage elements. The controller uses the meta data page to recall selected data pages from the low performance storage element onto the high performance storage element. The controller uses the meta data page to migrate selected data pages from the high performance storage element onto the low performance storage element.
