| 20100192160 | System, Device, and Method for Interprocessor Communication in a Computer System - A system, device, and method for interprocessor communication in a computer system utilizes a special Message Passing Service (MPS) to provide interprocessor communications. The MPS enables a client application running on one processor in a computer to communicate with a target application running a different processor in the same or a different computer. In order for the client application to communicate with the target application, the client application establishes a session to the target application over an existing communication link using the MPS. The MPS provides for both synchronous and asynchronous communication services. When the client application establishes the session to the target application, the client application specifies, among other things, a “callback” routine. The MPS invokes the “callback” routine to report certain asynchronous events to the client application. The MPS blocks the client application during certain synchronous operations so that the client application does not proceed until the synchronous operation is completed. | 07-29-2010 |

A data for a disposition of the communication is determined from a portion of the identified keywords, a portion of the call transport information, or a portion of the policies invoked. The communication is associated with the date(s). | 05-21-2009 |
| 20090089862 | Cross domain delegation by a storage virtualization system - The present is a system and method for preserving user account security privileges during a migration or re-direction of data from one network attached storage (“NAS”) system to another. Certain NAS systems authenticate user accounts using Kerberos Delegation Technology. In addition, some NAS systems feature the ability to constrain delegation to certain services. While effective in limiting access and promoting network security, this constrained delegation restricts the ability of a storage virtualization system to migrate or re-direct data to other NAS systems, especially if the other NAS system resides or is identified by a different domain name. The present invention is a system and method for storing user account credentials that work with the former NAS system, and providing a way to translate these credentials to a new NAS system with a new domain, permitting seamless data migration and re-direction across domains. | 04-02-2009 |
| 20090089522 | System and method for dynamic storage device reconfiguration - A system and method provides for recovery of a backup process that has been interrupted by an address change for a connected backup storage device. A backup server may manage a data backup process from client computers to backup storage devices, each device having a unique address. Devices may be managed by storage node computers, which may occasionally reorganize its associated devices, causing some device address changes. This will interrupt the backup process since the server will not be able to match reorganized devices to known addresses. The present invention provides a method for querying the backup storage device, updating the server with the new address change, and continuing with the backup process. The present invention also provides a method for disabling the device from the backup process if the problem cannot be solved, then resuming the backup process. | 04-02-2009 |
| 20090089395 | System and method for absolute path discovery by a storage virtualization system - A system and method provides for enabling a storage virtualization system to dynamically discover shares on a network attached storage file system is disclosed. Certain network attached storage systems represent user shares using abbreviated symbolic path names rather than full absolute path names. These network attached storage systems can correctly map the abbreviated path address to the actual file location; however, when a storage virtualization system is implemented to manage shares or files in these shares, it cannot access these files because it does not have the absolute path address. An embodiment of the present invention provides software instructions to augment the capabilities of the storage virtualization system, enabling it to map files with abbreviated share names, and therefore provide it with the ability to access these types of network attached storage systems. | 04-02-2009 |
| 20090089344 | Network accessed storage files system query/set proxy service for a storage virtualization system - A system and method provides for querying and setting file attributes between Network File System and Common Internet File System network attached storage systems. Aspects of the present invention may be performed by a storage virtualization system that acts as an intermediary between one or more network attached storage systems. By querying and setting file attributes, files may be migrated between network attached storage systems while keeping the file attributes and primary location of the file contents intact. In addition, the present invention provides an additional aspect of ensuring that file names of multi-protocol files are compatible across every protocol. | 04-02-2009 |
| 20090063795 | DE-DUPLICATION IN A VIRTUALIZED STORAGE ENVIRONMENT - A data de-duplication application de-duplicates redundant data in the pooled storage capacity of a virtualized storage environment. The virtualized storage environment includes a plurality of storage devices and a virtualization or abstraction layer that aggregates all or a portion of the storage capacity of each storage device into a single pool of storage capacity, all or portions of which can be allocated to one or more host systems. For each host system, the virtualization layer presents a representation of at least a portion of the pooled storage capacity wherein the corresponding host system can read and write data. The data de-duplication application identifies redundant data in the pooled storage capacity and replaces it with one or more pointers pointing to a single instance of the data. The de-duplication application can operate on fixed or variable size blocks of data and can de-duplicate data either post-process or in-line. | 03-05-2009 |
| 20090063528 | DE-DUPLICATION IN A VIRTUALIZED SERVER ENVIRONMENT - A data de-duplication application de-duplicates redundant data on the primary storage read/write pathway of a virtualized server environment. The virtualized server environment comprises one or more server applications operating on a virtualization layer provided on a computer architecture that includes memory (e.g., RAM, cache memory) for temporarily storing data and storage (e.g., disk storage) for persistently storing data. The one or more server applications use the read-write pathway to read data into memory from storage and to write data to storage from memory. The de-duplication application identifies redundant data in memory, storage, or both, and replaces the redundant data with one or more pointers pointing to a single copy of the data. The de-duplication application can operate on fixed or variable size blocks of data and can de-duplicate data either post-process or in-line. | 03-05-2009 |
| 20080219093 | Sensing System - The present invention relates to a sensing system, in particular to sensing system for sensing undersea seismic events. A vibration sensor is provided for sensing seismic vibrations on the sea bed is provided. The vibration sensor is electrically coupled to a transmitter unit, the transmitter unit being arranged to transmit, in use, an acoustic wave from which the presence of a seismic vibration can be inferred. The acoustic wave modulates light travelling along a nearby optical cable, the modulation being recovered at a distant monitoring station. A flotation arrangement is provide for retaining the transmitter unit in a raised position relative to the sea bed to facilitate the coupling of the acoustic wave to the optical cable. | 09-11-2008 |
