A plurality of data mover computers control access to respective file systems in data storage A network client serviced by any of the data movers can access each of the file systems If a data mover receives a client request for access to a file in a file system to which access is controlled by another data mover, then the data mover that received the client request sends a metadata request to the data mover that controls access to the file system The data mover that controls access to the file system responds by placing a lock on the file and returning metadata of the file The data mover that received the client request uses the metadata to formulate a data access command that is used to access the file data in the file system over a bypass data path that bypasses the data mover computer that controls access to the file system

File server system using file system storage, data movers, and an exchange of meta data among data movers for file locking and direct access to shared file systems

A storage controller has at least one physical data port for a data network including host processors. The storage controller is programmed to provide a plurality of virtual ports for access to storage, and a virtual switch for routing storage access requests from the physical port to the virtual ports. The virtual ports and the virtual switch are defined by software. The virtual ports appear to the hosts as physical ports in the data network. For example, in a Fiber-Channel network, the virtual ports have World Wide Names (WWNs) and are assigned temporary addresses (S_Ds), and the virtual switch provides a name server identifying the WWNs and S_IDs of the virtual ports. For convenient partitioning of storage among host processors, one or more virtual ports are assigned to each host, and a set of storage volumes are made accessible from each virtual port. A host can access storage at a virtual port only if the virtual port has been assigned to the host. Preferably, storage can be accessed through each virtual port by no more than one assigned host, although a shared volume may be accessible from more than one virtual port. The storage controller may provide a service for reporting to a host the virtual ports through which the host can access storage, and the storage volumes that are accessible to the host through each of the virtual ports.

A method, system, and computer program product for interactive searching with executable suggestions are provided. The present invention provides a search engine and data management technology that can understand what users are looking for, understand the data in a database, and present immediately useful suggestions for finding the right information. Executable suggestions are presented that enable a user to further narrow or broaden a search intelligently and adaptively in real-time. Each executable suggestion describes a search and corresponding search criteria and provides information on the actual search results a user will obtain according to this search criteria. In one embodiment of the present invention, a system has a suggestion engine and one or more suggestion spaces.

Interactive intelligent searching with executable suggestions

A client is permitted to send data access commands directly to network data storage of a network file server after obtaining a lock on at least a portion of the file and obtaining metadata indicating storage locations for the data in the data storage For example, the client sends to the file server at least one request for access to a file In response, the file server grants a lock to the client, and returns to the client metadata of the file including information specifying data storage locations in the network data storage for storing data of the file The client receives the metadata, and uses the metadata to produce at least one data access command for accessing the data storage locations in the network storage The client sends the data access command to the network data storage to read or write data to the file For a write operation, the client may modify the metadata When the client is finished writing to the file, the client returns any modified metadata to the file server

A system ( 120 ) detects transmission of potentially unwanted e-mail messages. The system ( 120 ) may receive e-mail messages and generate hash values based on one or more portions of the e-mail messages. The system ( 120 ) may then determine whether the generated hash values match hash values associated with prior e-mail messages. The system ( 120 ) may determine that one of the e-mail messages is a potentially unwanted e-mail message when one or more of the generated hash values associated with the e-mail message match one or more of the hash values associated with the prior e-mail messages.

An apparatus and method is provided for allocating a data file across a plurality of media servers in a network, wherein each media server has associated therewith one or more levels of I/O devices organized in a hierarchical manner An attempt is made to allocate the storage of data across the I/O devices in such a way that the bandwidth imposed on the devices when the data file is sequentially accessed will be balanced, and optimum use of I/O bandwidths at all points in the system is achieved This balancing can be done by incorporating knowledge regarding various bottlenecks in the system into the decisionmaking process required for distributing the data blocks The method and apparatus further allows bandwidths to be allocated to various clients in the system at the time a data file is opened Various checks are provided at the time a data file is accessed to ensure that the data rates actually imposed by the requesting client do not exceed that requested by the client at the time the data file was opened The invention allows for much more efficient use of the I/O resources in a system and ensures that a given configuration will be able to support client requests

Apparatus and method for data storage and retrieval using bandwidth allocation

A method for creating a multimedia presentation, which presentation comprises an audio or video recording of a session wherein a presenter presents an audiovisual presentation, said method comprising said presenter presenting said audiovisual presentation, making an audio or video recording of said presentation, wherein timing data comprising data for start, end and transition events within said audiovisual presentation are automatically, and without manual processing, incorporated into said audio or video recording, so as to allow said events to be used on playback to coordinate the audio or video portion of said multimedia presentation with the audiovisual portion thereof.

Method for capturing, encoding, packaging, and distributing multimedia presentations

A multimedia device includes input ports dedicated to receiving a real-time media signal and a processor system dedicated to capturing the real-time media signal. The processor system defines an embedded environment. The input ports and the processor system are integrated into the multimedia capture device. The input ports include an audio input port and at least one of a visual-capture input port or a digital-image input port.

Embedded appliance for multimedia capture

In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive, via a first communication mode, a first indicator associated with a first user-performed process, and receive, via a second communication mode different from the first communication mode, a second indicator associated with a second user-performed process. The code includes code to cause the processor to identify, using the first indicator a first set of items for the first user-performed process, and identify, using the second indicator, a second set of items for the second user-performed process. The code further includes code to cause the processor to define a vendor-agnostic list to include the first set of items and the second set of items, and send a signal associated with at least a portion of the vendor-agnostic list to a communication device.
