Distributed virtual tape library |
摘要 |
A system and method include a distributed virtual tape library node on a distributed computing system node and using a distributed computing system distributed file system to manage data on multiple nodes of the distributed computing system to form a distributed virtual tape library system. A master virtual tape library on a distributed computing system node, multiple slave virtual tape library on a different distributed computing system node, and a distributed computing system distributed file system to manage data on the master and slave virtual tape libraries form a distributed virtual tape library system. |

1. A method for implementing a distributed virtual tape library system that includes disk drive devices that emulate a tape drive, said method comprising:
providing a master virtual tape library node on a distributed computing system node; providing multiple slave virtual tape library nodes each on respective ones of multiple different distributed computing system nodes; providing a file on one or more of the master virtual tape library node and the slave virtual tape library nodes to identify a virtual tape library type; using a distributed file system to manage data on the master virtual tape library node and the multiple slave virtual tape library nodes; and using a map-reduce function in conjunction with the distributed file system to process application requests, wherein said using the map-reduce function in conjunction with the distributed file system includes,
receiving an application request; andusing the map-reduce function to divide the application request into multiple tasks, wherein the map-reduce function distributes each of the multiple tasks to any one of the multiple slave virtual tape library nodes of the distributed virtual tape library system. |
