Method And System For Caching Data In A Storgae System
view source
US Patent:

8032708, Oct 4, 2011
Filed:

Feb 11, 2009
Appl. No.:

12/369486
Inventors:

Brendan D. Gregg - San Francisco CA, US
Adam H. Leventhal - San Francisco CA, US
Bryan M. Cantrill - Piedmont CA, US
Assignee:

Oracle America, Inc. - Redwood City CA
International Classification:

G06F 12/00
US Classification:

711118, 711103, 711112, 711133, 711136, 711159
Abstract:

A method for caching data in a storage system involves receiving a request for a first datum stored on a storage disk, retrieving the first datum from the storage disk when a copy of the first datum is not stored on an asymmetric cache device (ACD), storing a first copy of the first datum in a main memory, updating a list of data to include the first datum, storing, prior to any data being evicted from the main memory, a second copy of the first datum on the ACD, and evicting the first copy of the first datum from the main memory when a first copy of a second datum is designated for storing in the main memory and the main memory is full and the first datum is at the tail of the list of data.

US Patent:

8468251, Jun 18, 2013
Filed:

Dec 29, 2011
Appl. No.:

13/340461
Inventors:

William D. Pijewski - San Francisco CA, US
Gerald A. Jelinek - Colorado Springs CO, US
Brendan Gregg - Walnut Creek CA, US
Bryan Cantrill - Piedmont CA, US
Assignee:

Joyent, Inc. - San Francisco CA
International Classification:

G06F 15/16
G06F 15/173
US Classification:

709226, 709215, 709235
Abstract:

Systems, methods, and media for method for managing requests for computing resources are provided herein. Methods may include dynamically throttling requests for computing resources generated by one or more tenants within a multi-tenant system, such as a cloud. In some embodiments, the present technology may dynamically throttle I/O operations for a physical storage media that is accessible by the tenants of the cloud. The present technology may dynamically throttle I/O operations to ensure fair access to the physical storage media for each tenant within the cloud.

US Patent:

8547379, Oct 1, 2013
Filed:

Dec 29, 2011
Appl. No.:

13/340488
Inventors:

David Pacheco - San Francisco CA, US
Brendan Gregg - Walnut Creek CA, US
Bryan Cantrill - Piedmont CA, US
Assignee:

Joyent, Inc. - San Francisco CA
International Classification:

G06T 11/20
US Classification:

345440
Abstract:

Systems, methods, and media for generating heat maps of event data are provided herein. Methods may include gathering instances of event data according to a performance characteristic, discretely decomposing the instances by applying at least one constraint to the instances, assigning a hue to each instance, the hue being associated with the at least one constraint, and generating a heat map that includes representations of the instances, wherein each representation includes the hue associated with the at least one constraint to which the instance has been assigned.

Method And System For Accessing Data Using An Asymmetric Cache Device

US Patent:

20090249007, Oct 1, 2009
Filed:

Apr 1, 2008
Appl. No.:

12/060761
Inventors:

Adam H. Leventhal - San Francisco CA, US
Brendan D. Gregg - Menlo Park CA, US
Bryan M. Cantrill - San Francisco CA, US
Assignee:

SUN MICROSYSTEMS, INC. - Santa Clara CA
International Classification:

G06F 12/00
US Classification:

711162, 711E12001
Abstract:

A system configured to receive a first request for a first datum, query the cache metadata to determine whether the first datum is present in the main memory or the asymmetric cache device (ACD), retrieve the first datum from the main memory when the first datum is present in the main memory, retrieve the first datum from the ACD when the first datum is present in the ACD and not present in the main memory, store a copy of the first datum in the main memory when the first datum is present in the ACD and not present in the main memory, update the cache metadata to indicate that the copy of the first datum is stored in the main memory when the first datum is present in the ACD and not present in the main memory, and retrieve the first datum from the disk when the first datum is not present in the ACD and is not present in the main memory.
