Primary Stub File Retention And Secondary Retention Coordination In A Hierarchical Storage System

View page
US Patent:
8170985, May 1, 2012
Filed:
Jan 31, 2006
Appl. No.:
11/343313
Inventors:
Eyal Zimran - Richmond, GB
Christian J. Chuba - Berkeley Heights NJ, US
Christopher H. Stacey - Swindon, GB
Mary Walker - Windham NH, US
Assignee:
EMC Corporation - Hopkinton MA
International Classification:
G06F 17/00
US Classification:
707609, 707661, 707640, 707682, 707821, 707826
Abstract:
A protected file is retained in secondary storage for a retention period, and a corresponding stub file is retained in primary storage for the retention period. The stub file retains attributes of the file indicating a location of the file data in the secondary storage and indicting that the stub file is to be retained for the retention period. A system administrator may instruct a primary file server that a secondary file server supports retention based protection and it is desired to protect stub files corresponding to protected files that are migrated to the secondary file server. The primary file server may request the secondary file server to return a protection status of the file after migration. This enables automatic policy-based migration to both file level retention (FLR) and non-FLR retention protected secondary storage from diverse applications accessing FLR or non-FLR files in the primary storage.

Method And Apparatus For Performing Bulk File System Attribute Retrieval

View page
US Patent:
8560569, Oct 15, 2013
Filed:
Jan 27, 2006
Appl. No.:
11/341353
Inventors:
Ivan Basov - Westborough MA, US
Christian J. Chuba - Berkeley Heights NJ, US
Stephen A. Fridella - Belmont MA, US
Uday K. Gupta - Westford MA, US
Xiaoye Jiang - Shrewsbury MA, US
Christopher Stacey - Swindon, GB
Jiannan Zheng - Ashland MA, US
Eyal Zimran - London, GB
Assignee:
EMC Corporation - Hopkinton MA
International Classification:
G06F 17/30
US Classification:
707771, 707770, 707E17014
Abstract:
Accordingly a method and interface allows an attribute data base used by an Information Manager to be quickly populated and accurately maintained. A single Bulk Attribute Retrieval Request triggers the primary storage device to collect object attribute information. The method allows for selective collection of objects and attributes by providing filters and attribute lists in the Requests. The Request may be used to provide an incremental scan with appropriate time stamp filtering. In addition, the size of the results can be controlled by the IM by eliminating attributes that are not of interest to the IM. The Request is advantageously issued over a FileMover interface, which is an HTTP connection, and encoded in XML, allowing the IM to easily customize the Request as desired.

Detection Of Single-Frequency Signals

View page
US Patent:
48496880, Jul 18, 1989
Filed:
Sep 16, 1988
Appl. No.:
7/247049
Inventors:
Christian J. Chuba - Scotch Plains NJ
Charles R. Walden - Montclair NJ
Joseph J. Grecco - Saddle Brook NJ
Jeffrey I. Feinstein - Clifton NJ
Assignee:
Dialogic Corporation - Parsippany NJ
International Classification:
G01R 2302
US Classification:
324 78R
Abstract:
Apparatus for detecting a single-frequency signal having a predetermined frequency in an analog signal includes means for converting the analog signal to a differentially encoded digital signal and detection means for detecting a single-frequency signal having the predetermined frequency from the differentially encoded digital signal. In a preferred embodiment, the detection means includes: means for detecting one cycle of the analog signal by detecting a signal maximum followed by detecting a signal minimum which is followed, in turn, by detecting another signal maximum; means for determining the length of the cycle, for determining whether the length is within predetermined bounds, and for keeping a count of such occurrences; and means for determining whether the count has reached a predetermined amount, whereby a single-frequency signal having the predetermined frequency has been detected.
