Abstract

A method and system for improving a shared memory file transfer setup and usage is provided. The method includes configuring network links connected between hardware nodes. For every shared storage link, each hardware node includes a command section and a data storage section. A storage capacity for a hardware disk drive is determined based on a number of the hardware nodes and the hardware disk drive is connected to the hardware nodes. A software agent is installed within each of the hardware nodes and properties for the network links are configured. Each software agent is enabled and a connectivity status, bandwidth, and loading condition are tested for each of the network links. Each hardware node is registered with the hardware disk drive and communications between the hardware disk drive and the hardware nodes are enabled via the network links.

First claim

What is claimed is:

1. A shared memory file transfer setup and improvement method comprising:
configuring, by a processor of a network controller hardware device, a plurality of network links connected between a plurality of hardware nodes, wherein each hardware node of said plurality of hardware nodes comprises a command section and a data storage section;
determining, by said processor based on a number of said plurality of hardware nodes, a storage capacity for a hardware disk drive;
connecting based on said storage capacity, by said processor via at least one storage link, said hardware disk drive to said plurality of hardware nodes;
configuring, by said processor, properties for said plurality of network links and said at least one storage link;
testing, by said processor executing a software agent installed within each of said plurality of hardware nodes, a connectivity status, a bandwidth, and a loading condition for each of said plurality of network links and said at least one storage link;
registering, by said processor via each said command section, each said hardware node with said hardware disk drive; and
enabling, by said processor, communications between said hardware disk drive and said plurality of hardware nodes via said plurality of network links and said at least one storage link.

2. The method of claim 1 , wherein said determining said storage capacity for a hardware disk drive is further based on a bandwidth for each of said plurality of network links.

3. The method of claim 1 , wherein said properties for said plurality of network links and said at least one storage link comprise a priority level for said plurality of network links and said at least one storage link and a specified timeframe associated with said testing.

4. The method of claim 1 , wherein said plurality of network links comprise TCP/IP network links.

5. The method of claim 1 , further comprising:
providing at least one support service for at least one of creating, integrating, hosting, maintaining, and deploying computer-readable code in the control hardware, said code being executed by the computer processor to implement: said configuring said plurality of network links, said determining, said connecting, said configuring said properties, said testing, said registering, said enabling said communications.

6. A shared memory file transfer usage and improvement method comprising:
receiving, by a processor of a receiver host hardware node, a request for transferring a data file from an additional hardware node;
determining, by said processor, a current file transfer status of said receiver host hardware node;
selecting, by said processor, executing software code, a specified file transfer process for transferring said data file;
receiving, by said processor in accordance with execution of said specified file transfer process, a summary describing said data file;
receiving, by said processor from said additional hardware node via a plurality of network links, a storage link, and a storage device, a plurality of data segments of said data file, wherein said plurality of network links, said storage link, and said storage device are connected between said receiver host hardware node and said additional hardware node;
transmitting by said processor to said additional hardware node, an acknowledgment notification for each segment of said plurality of data segments indicating successful receipt of each said segment;
recording, by said processor, a transfer rate for each said segment being transferred, via said plurality of network links, said storage link, and said storage device from said additional hardware node to said receiver host hardware node;
determining, by said processor, that all segments of said data file have been received by said receiver host hardware node; and
constructing, by said processor, said data file from said plurality of data segments.

7. The method of claim 6 , wherein said request is determined based on an availability of each of said plurality of network links.

8. The method of claim 7 , wherein said request is further determined based on an associated priority level for each of said plurality of network links.

9. The method of claim 6 , further comprising:
storing, by said processor, each said transfer rate determined during said recording.

10. The method of claim 6 , wherein said plurality of network links comprise TCP/IP network links.

11. A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, said computer readable program code comprising an algorithm that when executed by a processor of a host hardware node implements a shared memory file transfer usage and improvement method, said method comprising:
receiving, by said processor, a summary describing a data file to be transferred from an additional hardware node;
receiving, by said processor from said additional hardware node via a plurality of network links, a storage link, a storage device, a plurality of data segments of said data file, wherein said plurality of network links, said storage link, and said storage device are connected between said receiver host hardware node and said additional hardware node;
transmitting by said processor to said additional hardware node, an acknowledgment notification for each segment of said plurality of data segments indicating successful receipt of each said segment;
recording, by said processor, a transfer rate for each said segment being transferred, via said plurality of network links, said storage link, and said storage device from said additional hardware node to said receiver host hardware node;
determining, by said processor, that all segments of said data file have been received by said receiver host hardware node; and
constructing, by said processor, said data file from said plurality of data segments.

12. The computer program product of claim 11 , wherein said request is determined based on an available of each of said plurality of network links.

13. The computer program product of claim 12 , wherein said request is further determined based on an associated priority level for each of said plurality of network links.

14. The computer program product of claim 11 , wherein said method further comprises:
storing, by said processor, each said transfer rate determined during said recording.

15. The computer program product of claim 11 , wherein said plurality of network links comprise TCP/IP network links.

16. A shared memory file transfer usage and improvement method comprising:
determining, by a processor of a transmitter host hardware node, an available number of a plurality of network links for transferring a data file between said transmitter host hardware node and a receiver host hardware node via a storage device;
determining, by said processor, an associated priority level for each of said plurality of network links;
dividing, by said processor in response to receiving a request for transferring said data file to said receiver host hardware node, said data file into a plurality of segments;
assigning, by said processor, a transmission sequence to said plurality of segments;
transmitting, by said processor to said receiver host hardware node, a summary describing said data file;
determining, by said processor, a transfer ratio for each of said plurality of network links;
