Scalable multimedia file system supports workstation to perform requested file operation, when sufficient network bandwidth and disk capacity are available

摘要

An access controller in cluster manager (404), regulates the file access request from workstation (408). A network status determination device and a disk status determination device determine network bandwidth and disk capacity, respectively response to file access request from workstation. The file system supports requested file operation, if available network bandwidth and disk capacity are sufficient. The file system (400) is divided into clusters (401) having a disk (402), cluster manager (404) and file manager (406). Access controller in the cluster manager regulates the file access request from workstation (408). A network status determination device in the file manager, determines the available network bandwidth, in response to the access request from workstation. A disk status device determines the available disk capacity in response to the file access request. The system supports requested file operation if the available network bandwidth and disk capacity are sufficient. An Independent claim is also included for file access control method.
