ACTIVITY-BASED BLOCK MANAGEMENT OF A CLUSTERED FILE SYSTEM USING CLIENT-SIDE BLOCK MAPS

摘要

A technique for operating a client node in a clustered file system includes allocating a number of blocks during a first time window and tracking the number of blocks allocated during the first time window. The technique further includes transmitting a block allocation request to a server node of the clustered file system for a number of requested blocks in response to a number of free blocks in a client-side block map reaching a first threshold value. In this case, the number of the requested blocks is based on the number of blocks allocated by the client node during the first time window.
