Patent number: 8713252Abstract: A proxy manages write operations between devices that initiate write operations and one or more storage devices that store data for the write operations. A write log buffers the data for the write operations while the proxy waits for acknowledgments back from the storage device. The proxy is configured to copy at least some of the data from the write log into an overflow log when the data from the write operations is about to overflow the write log. The proxy device is further configured to maintain data consistency by delaying or blocking read operations until associated data from previously received write operations is acknowledged by the storage device.Type: GrantFiled: May 4, 2010Date of Patent: April 29, 2014Assignee: Violin Memory, Inc.Inventors: Erik de la Iglesia, Som Sikdar, Ross Becker

Patent number: 8650362Abstract: A storage system creates an abstraction of flash Solid State Device (SSD) media allowing random write operations of arbitrary size by a user while performing large sequential write operations of a uniform size to an SSD array. This reduces the number of random write operations performed in the SSD array and as a result increases performance of the SSD array. A control element determines when blocks from different buffers should be combined together or discarded based on fragmentation and read activity. This optimization scheme increases memory capacity and improves memory utilization and performance.Type: GrantFiled: April 13, 2010Date of Patent: February 11, 2014Assignee: Violin Memory Inc.Inventors: Erik de la Iglesia, Som Sikdar

Patent number: 8463800Abstract: Regular expressions used for searching for patterns in captured objects can be grouped into attributes. Such attributes can be associated with captured objects using tags stored in a database. In one embodiment, the present invention includes capturing an object being transmitted over a network, and determining that a regular expression appears in the object, the regular expression belonging to a group of one or more regular expressions associated with an attribute. If a regular expression associated with the attribute is found in the object, then an attribute field of a tag containing metadata related to the captured object is set to indicate the presence of the attribute in the captured object. The presence of the attribute in the captured object can now be determined from the tag, which can be stored in a database.Type: GrantFiled: March 27, 2012Date of Patent: June 11, 2013Assignee: McAfee, Inc.Inventors: William Deninger, Erik de la Iglesia
