20090210742	Methods, systems and media for data recovery using global parity for multiple independent RAID levels - Implementations described herein generally provide methods, systems and media for recovering data from disk failures. One method generally includes calculating a global parity for a group of disks comprising multiple independent RAID (Redundant Array of Independent Disks) arrays; determining if a two disk failure has occurred within a single RAID array; and if so, recovering from the two disk failure using the global parity and data from the RAID arrays.	08-20-2009

20090161247	Channel Skew Identification and Notification - Embodiments of the present invention analyze a plurality of parallel channels and identify specific channel(s) that have skew outside of an acceptable skew error margin. In certain embodiments, this skew is identified by determining the timing misalignment between a channel under test and a deskew channel. Other channels within the plurality of channels are masked by transmitting a repeating masked bit pattern. This timing misalignment may be measured by comparing a segment within the channel under test to a corresponding segment within the deskew channel and identifying a time differential between the two segments.	06-25-2009

20100037287	METHOD AND APPARATUS FOR PROVIDING ROUTING AND ACCESS CONTROL FILTERS - A method and apparatus for providing an access control filter and/or a route filter in a network are disclosed. For example, the method receives a new filter rule or a modified filter rule associated with at least one of: a routing policy, or a security policy. The method creates or modifies one or more filter templates in accordance with the new filter rule or the modified filter rule. The method identifies one or more affected interfaces and audits the one or more affected interfaces. The method then generates one or more commands in accordance with the one or more filter templates if the auditing of the one or more affected interfaces is successful, and downloads filter content to one or more routers using the one or more commands.	02-11-2010
