Abstract
Improving extent-based read performance using pre-fetches by utilizing synthesized sequential extent files in a deduplication storage system. Synthesized content for the extents is created on a server. The synthesized content is headed by a content handle and stored in a stateful context data structure for lookup by the client. This enables an extent read workflow to be supported on a storage system without an added cache required to achieve sufficient random read performance by synthesizing content into a inode-less file. It improves extent reads at random offsets by synthesizing the extents to leverage the sequential restore performance, and leverages delta files to improve read performance for extent reads.
