Media stream distribution system
View Patent ↗A media server comprises a plurality of nodes each comprising a gateway, each gateway providing memory and communication of data between mass storage and I/O ports of a node, and/or providing communication of data between the node and other nodes. Each node utilizes one or more central processors. The media server comprises logic to enable the processors to manage the streaming of data from the mass storage to the I/O ports via the gateways without communicating the data between the processors and any of the mass storage, I/O ports, or gateways.
1. A media server comprising:
a plurality of nodes each comprising a gateway, each gateway providing memory and communication of data between mass storage and I/O ports of a node;
each node utilizing one or more central processor and processor memory; and
the media server comprising non-transitory machine readable media or memory devices embodying logic to enable the central processor of one or more selected nodes from the plurality of nodes to manage the streaming of data from the mass storage of the one or more selected nodes via the gateway of the one or more selected nodes to the I/O ports of the one or more selected nodes while the streamed data bypasses the central processors and processor memory of the one or more selected nodes.
2. The media server of claim 1 , further comprising:
non-transitory machine readable media or memory devices embodying logic to cause mass storage and gateway memory of the at least two nodes to appear to the central processors as a single mass storage volume and cache memory, respectively.
3. The media server of claim 1 , further comprising:
non-transitory machine readable media or memory devices embodying logic to determine whether one or more addresses of data to stream refers to data stored by non-local gateway memory, and if so, to retrieve the data from the non-local gateway memory to the node that is streaming the data.
4. The media server of claim 1 , further comprising:
the first and second nodes comprising a single console and interfaces to nodes of other consoles.
5. The media server of claim 4 , further comprising:
nodes within the single console communicating stream data between themselves primarily via gateways of the nodes within the single console.
6. The media server of claim 1 , further comprising:
the first and second nodes coupled to a console interface comprising independent physical communication channels to multiple nodes of other consoles.
7. The media server of claim 6 , further comprising:
the first and second nodes coupled to nodes of another console by a cable comprising four independent physical communication channels, with the first node having two independent physical communication channels to a first node in another console, and the second node having two independent physical communication channels to a second node in the another console.
8. The media server of claim 6 , further comprising:
multiple independent communication channels in each cable connecting two consoles, a pair of independent communication channels connecting each node in a first console with a partner node in a second console.
9. A node of a multi-processor system comprising:
mass storage; at least one central processor;
processor memory providing storage for data read from or written to the mass storage by the central processor;
an I/O interface; and
a media server comprising non-transitory machine readable media or memory devices embodying logic to enable the central processor to manage the streaming of data from the mass storage to the I/O interface without reading or writing the streamed data to the processor and/or processor memory.
10. The node of a multi-processor system of claim 9 , further comprising:
at least one gateway providing communication of stream data between the mass storage, the I/O interface, and an interconnect to other nodes of the multi-processor system; and
non-transitory machine readable media or memory devices embodying logic to enable the central processor to manage the streaming of data from the mass storage to the I/O interface via the gateway without communicating the data between the central processor and any of the mass storage gateway, or I/O interface.
11. The node of a multi-processor system of claim 9 , further comprising:
non-transitory machine readable media or memory devices embodying logic to enable the central processor to cause the communication of data stream blocks from the mass storage of the node or the mass storage of another node to the I/O interface, without communicating contents of the blocks to the central processor or the processor memory.
12. A computer-implemented method, comprising: providing a plurality of gateways within a plurality of nodes, respectively, each gateway providing memory and communication of data between mass storage and I/O ports of a node, and each of the plurality of nodes comprising one or more central processors and processor memory;
streaming of data from a mass storage of one or more selected nodes from the plurality of nodes via gateways associated with the one or more selected nodes to the I/O ports of the one or more selected nodes; and
managing the streaming from the mass storage of the one or more selected nodes such that the streamed data bypasses the central processors and processor memory of the one or more selected nodes.
13. The computer-implemented method of claim 12 , further comprising causing the mass storage and gateway memory of the plurality of nodes to appear to the central processors as a single mass storage volume and cache memory, respectively.
14. The computer-implemented method of claim 12 , further comprising:
determining whether one or more addresses of data to stream refer to data stored by non-local gateway memory; and
based upon determining that the addresses refer to data stored by non-local gateway memory, retrieving the data from the non-local gateway memory to the node that is streaming the data.
15. The computer-implemented method of claim 12 , wherein a first node and a second node from the plurality of nodes comprise a single console and interfaces to nodes of other consoles.
16. The computer-implemented method of claim 15 , further comprising communicating stream data between the first node and the second node primarily via gateways of the nodes within the single console.
17. The computer-implemented method of claim 12 , further comprising coupling a first node and a second node from among the plurality of nodes to a console interface comprising independent physical communication channels to multiple nodes of other consoles.
18. The computer-implemented method of claim 17 , wherein the first node and the second nodes are coupled to nodes of another console by a cable comprising four independent physical communication channels, with the first node having two independent physical communication channels to a first node in another console, and the second node having two independent physical communication channels to a second node in the another console.
19. The computer-implemented method of claim 17 , wherein multiple independent communication channels in each cable connect two consoles, a pair of independent communication channels connecting each node in a first console with a partner node in a second console.
