Patent number: 9418015Abstract: Among other things, one or more techniques and/or systems are provided for storing data within a hybrid storage aggregate comprising a lower-latency storage tier and a higher-latency storage tier. In particular, frequently accessed data, randomly accessed data, and/or short lived data may be stored (e.g., read caching and/or write caching) within the lower-latency storage tier. Infrequently accessed data and/or sequentially accessed data may be stored within the higher-latency storage tier. Because the hybrid storage aggregate may comprise a single logical container derived from the higher-latency storage tier and the lower-latency storage tier, additional storage and/or file system functionality may be implemented across the storage tiers. For example, deduplication functionality, caching functionality, backup/restore functionality, and/or other functionality may be provided through a single file system (or other type of arrangement) and/or a cache map implemented within the hybrid storage aggregate.Type: GrantFiled: April 24, 2015Date of Patent: August 16, 2016Assignee: NetApp, Inc.Inventors: Rajesh Sundaram, Douglas Paul Doucette, David Grunwald, Jeffrey S.

Patent number: 9152600Abstract: A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that “virtualizes” a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.Type: GrantFiled: July 18, 2013Date of Patent: October 6, 2015Assignee: NetApp, Inc.Inventors: Jason Ansel Lango, Robert M.

Patent number: 9128942Abstract: Many applications and computing environments allow users to migrate data from a source object to a target object (e.g., a file may be cut/pasted, copied, etc.). It may be advantageous to provide users with access to the data (e.g., migrated data at the target object and/or data that has yet to be migrated from the source object) before all of the data is completely migrated (e.g., a user may otherwise have to wait hours for a 2 TB file to be copied between various data volumes). Accordingly, as provided herein, migration of a source object to a target object may be declared as completed, even though the target object may not comprise all of the data that is to be migrated. In this way, an I/O request may be satisfied based upon migrated data within the target object and/or data, not yet migrated, retrieved on-demand from the source object.Type: GrantFiled: December 24, 2010Date of Patent: September 8, 2015Assignee: NetApp, Inc.Inventors: Jeffrey Pfau, Devang K. Shah, Amber Palekar, Ashish Prakash
