Abstract:
Disclosed is a method and apparatus for a variable media tape based storage system for storing, retrieving, and communicating data. The system includes at least one media element having a compatible relationship with one of a plurality of drives for storing and receiving data. The at least one media element configured to operate with the at least one drive as a functional pair is considered a loaded drive. The storage system also includes switch and mapping system, which in one embodiment could be an interface bridge processor, operatively linked to each of the plurality of drives. Finally, the storage system adapted to alter at least one received and accepted tape library command from positioning a target storage tape article for use with a target tape drive to selecting one of the loaded drives via the interface bridge processor. The interface bridge processor can be adapted to receive data in a streaming protocol to be saved on the target storage tape article by the target storage drive and convert the streaming protocol to a different protocol to save the data on the physically selected loaded drive.

US Classification:
714 14, 711114
Abstract:
Disclosed is a method and apparatus relating generally to analysis techniques for data integrity following an un-safe power down occurrence of non-tape media components comprising a storage system. The data storage system comprises at least one random access memory storage device adapted to be power cycled in at least an on and off condition. The random access memory storage device comprises at least one storage medium comprising a first stored data segment. The storage device is adapted to receive data for storage on the medium in at least a second data segment. At least one state bit has a first state associated with the second data segment during the storage of the second data segment and a second state associated with the second data segment after completion of the storage of the second data segment wherein the state bit is stored in non volatile memory associated with the storage device. The state bit is capable of being accessed to determine completion status of the storage of at least the second data segment after the storage device is power cycled in the on condition.
Random Access Storage System Capable Of Performing Storage Operations Intended For Alternative Storage Devices
Disclosed are a method and apparatus for a storage system comprising at least one mobile random access storage device capable of storing first and second data on at least one docking station. The docking station is associated with an address wherein the address is identifiable by at least one host computer. A first and second sub-address are associated with the docking station wherein the first and second sub-addresses are identifiable by the host computer. The first sub-address corresponds to a first virtual device adapted for storing the first data on a first virtual media. The second sub-address corresponds to a second virtual device adapted for storing the second data on a second virtual media wherein the second virtual media is different from the first virtual media. The docking station is adapted to be responsive to the host computer as available for storing the first data at the first sub-address and the second data at the second sub-address when the docking station is operatively linked with the mobile random access storage device.

Abstract:
A method and apparatus for a generating a tape format like file with an associated look-up table on a non-tape storage medium is disclosed. In one configuration, a data storage arrangement can comprise a host computer in communication with a storage system by means of a streaming protocol. The storage system can comprise a non-tape storage medium having at least one file comprising a plurality of records each having user data and meta data wherein the meta data comprises data fields for and about the record. A table associated with the file is adapted to contain information related to at least one of the records. The table can be accessed by the storage system to reduce the amount of time spent locating the records.

Abstract:
Disclosed is a method and apparatus relating generally to erasure techniques for emulating a streamed data format for non tape media capable of being used with a data storage arrangement to generate replenished user data space. The data storage arrangement comprises a host computer and a storage system in communication with the host computer, the storage system comprising at least one random access storage medium. The random access storage medium is capable of receiving data by streaming protocol and storing the data emulated in a contiguous format. The data comprises at least one data file which further comprise a plurality of records wherein each of the records comprise user data and meta data. A deletion algorithm is adapted to issue at least one deletion command capable of deleting at least one portion of the data stored on the medium up to at least a last segment of the data to create replenished storage space. The replenished storage space is capable for storage of new data in an order following the last segment of data upon receiving the new data in the streaming protocol by the storage medium.

US Classification:
710/001000
Abstract:
A method and system for characterizing data storage usage by a host in a data storage system that provides a host-specific access area in a storage device. Access is gained to the access area and blocks of data from the access area are retrieved and stored in buffers. The stored data is classified as allocated as an organized data structured defined by a particular file system or non-typical system. The classifying includes sequentially mapping the data into file system data structures until a match is obtained and then the mapped data structure is stored. The match is verified by retrieving expected values for a file system and comparing the mapped values with the expected values. The mapped data is used to determine host storage information, such as number of blocks, number of the used data blocks, free space, number of files, location of files, and size of files.
