Abstract:
As storage systems grow larger and more
complex, the traditional block-based file systems
cannot satisfy the large workload. More recent
distributed file systems have adopted
architectures based on object-based storage.
This paper presents a framework of efficient
storage management for distributed storage
system. In object storage side which manage disk
block allocation internally by object-based
storage devices (OSDs), low-level storage tasks
and data distribution must be managed, and in
metadata server side, we will manage how to
scale the metadata. Due to the high space
efficiency and fast query response, we will utilize
bloom-filter based approach to manage
metadata and add semantic-based scheme to
narrow the managed workload. Then we will
optimize the data distribution in OSDs using
chord mechanism.
