Filed:

Aug 7, 2003

Appl. No.:

10/636042

Inventors:

Steven A. Justiss - Lakeway TX, US
Robert Sims - Round Rock TX, US

Assignee:

Crossroads Systems, Inc. - Austin TX

International Classification:

G06F 12/00

US Classification:

711111, 711162, 711 4, 707 7

Abstract:

Systems and methods for performing multi-threaded backups and restores. In one embodiment, a log is maintained to record the source of write commands, and the order in which blocks of data are written to a sequential storage device. The source identification of the write command may consist of such identifiers as a protocol dependent Host ID, the extended-copy-specification-defined List ID, a time stamp, and the size of the backup medium block written. The order in which the data is written to the backup medium can be identified with these same Host ID and List ID numbers. When it is desired to restore data corresponding to one of the threads, the desired blocks of data can be identified in the log, and the preceding blocks stored on the backup medium can be skipped.

US Classification:

711162, 711161, 711111, 711 4, 714 13

Abstract:

Embodiments of the present invention provide systems and methods for backing up data through recordation and issuance of extended copy and media commands. One embodiment of the present invention can include a method for backing up data comprising, receiving one or more extended copy commands for a requested operation, receiving one or more media commands for the operation, recording the one or more media commands, recording the one or more extended copy commands and retrieving and issuing the recorded one or more extended copy commands and the recorded one or more media commands for the operation to perform the requested operation.

Inventors:

Robert Sims - Round Rock TX, US

Assignee:

Crossroads Systems, Inc. - Austin TX

International Classification:

G06F 12/00

US Classification:

711111, 369 3401, 711202

Abstract:

Embodiments of the present invention provide a media library controller that can communicate with multiple physical libraries that are physically separate from each other. The media library controller can maintain a virtualized aggregate media library representing the physical media libraries with which it is in communication. From the physical media libraries, the media library controller can establish a virtual media library and associate a host with the virtual media library. The virtual media library can represent the portions of a physical media library to which the host is allowed access.

Robert C. Sims - Round Rock TX, US

Assignee:

Crossroads Systems, Inc. - Austin TX

International Classification:

G06F 15/173

US Classification:

709224, 709221, 709223, 711111, 711112, 714 47, 713190

Abstract:

Embodiments of methods and systems comprise collecting data associated with a library or library components and storing the collected data in repository. By collecting data associated with a library or library components and storing the collected data in a repository, the degradation of library components can be monitored and the reliability of library components determined, allowing unreliable components to be bypassed or replaced, enhancing the reliability of the library and preventing data loss.

Appl. No.:

12/025322

Inventors:

Robert C. Sims - Round Rock TX, US

Assignee:

Crossroads Systems, Inc. - Austin TX

International Classification:

H04L 12/26

US Classification:

370253, 370254

Abstract:

Embodiments provide systems and methods for diagnosing a network and identifying problems in a network which reduce the data transfer rate of data through the network. One embodiment of a method for network diagnosis may include infusing data into a network upstream and downstream of a portion of the network relative to a library drive, querying the drive at intervals over time for drive data to determine the data transfer rate at the drive and comparing the data transfer rate of the data infused upstream of the device or network portion with the data transfer rate of the data infused downstream of the device or network portion to determine throughput. By comparing the data transfer rate of data infused upstream and downstream of a network device or network portion, problem devices in a network may be identified.

Inventors:

Robert C. Sims - Round Rock TX, US

Assignee:

Crossroads Systems, Inc. - Austin TX

International Classification:

G06F 21/00

US Classification:

713193, 713189, 713191, 725 25, 380201, 380277

Abstract:

Embodiments provide systems and methods for the encryption of data to be stored on media in a library. A method of data encryption may comprise intercepting or monitoring commands sent to a library comprising one or more media stored at secure slots. If in response to a command or commands, media is moved from a secure slot to a drive, data stored on the media by the drive is encrypted, either by an encryption device, the drive or other encryption system, thus allowing encryption based on individual slots or media in a library.

Abstract:

Embodiments of systems and methods for implementing a file system utilizing a media library are disclosed. In particular, embodiments may present a network based file system to one or more host devices. These host devices may utilize the network based file system to organize, store, read or perform other operations in association with files. These files may be managed in conjunction with the media library.
