Systems, methods, and computer program products for streaming video data to a user. In one implementation, the video includes first video data and second video data. The user is allowed to fast-forward the first video data but is not allowed to fast-forward the second video data. The first video data is stored on a first member of data storage and the second video data is stored on a second member of the data storage. In one implementation, a module is operable to read the video data from a first and a second portion of a virtual partition, and to refuse a request to fast-forward any video data stored on the second portion.

Streaming video data with fast-forward and no-fast-forward portions

A system and a method manages storage space in one or more data storage devices. This is done by receiving a request for storage space from a requester, the request specifying one or more criteria associated with the requested storage space; searching a data structure such as a table containing attributes associated with the data storage devices; selecting one of the data storage devices whose attributes best match the one or more criteria; returning an identification associated with a portion of the selected data storage devices to the requester; and creating a communication path between the requester and the selected data storage device.

Intelligent virtual volume access

A scalable computer system has an interconnect bus providing communication links among a host processor and one or more function-specific processors, including a network processor (NP) and a file storage processor (FSP). The host processor provides a single interface to network administrators for maintaining the system. A bi-endian conversion system is provided to minimize a need for translating between big and little endian data types generated by diverse processors. The NP shares a single memory image with other processors and has a buffer memory for buffering requests from the network interfaces. The buffer memory has one or more segments which are dynamically allocatable to different processors. The FSP has a metadata cache for maintaining information on data being cached in the NP buffer memory. The FSP also has a write cache for buffering file write operations directed at disks. Upon receiving requests for data from the NP, the FSP checks the metadata cache to see if a copy of the requested data has been cached in the NP buffer and, if the copy exists in the NP buffer, causing the NP with the data to respond to the request. The resulting scalable computer provides higher data availability, faster access to shared data, and reduced administrative costs via data consolidation.
