| 7725768 | System and method for handling a storage resource error condition based on priority information Various embodiments of systems and methods are disclosed for using priority information when handling error conditions for a storage resource. In some embodiments, a method involves detecting an error condition, which is associated with a storage resource, and selec... | 05/25/2010 |
| 7657744 | System and method for dynamically determining the role of a network device in a link authentication protocol exchange Various methods and systems for dynamically determining the role of a network device in a link authentication protocol exchange are disclosed. In one embodiment, such a method involves monitoring several (e.g., two) link authentication protocol exchanges. These link... | 02/02/2010 |
| 7551559 | System and method for performing security actions for inter-layer binding protocol traffic Users are allowed to specify per-interface rate limits for inter-layer binding protocol traffic. If the user-specified rate limit is exceeded on a given interface, inter-layer binding protocol messages received via that interface are caused to be dropped (e.g., by s... | 06/23/2009 |
| 7529199 | System and method for resolving conflicts in proxy routing information associated with multicast distribution trees A first message, received from a first device, identifies a multicast distribution tree and includes first information associated with a route leading to a root of the multicast distribution tree. A second message, received from a second device, also identifies that... | 05/05/2009 |
| 7436836 | Method and apparatus for detecting support for a protocol defining supplemental headers Various methods and systems for detecting whether a network device supports a protocol, which defines a supplemental header, are disclosed. One method involves detecting a value within a preamble generated by a sending device and verifying that a header format of a ... | 10/14/2008 |
| 7409586 | System and method for handling a storage resource error condition based on priority information Various embodiments of systems and methods are disclosed for using priority information when handling error conditions for a storage resource. In some embodiments, a method involves detecting an error condition, which is associated with a storage resource, and selec... | 08/05/2008 |
| 7409512 | Method and apparatus for maintaining information that indicates valid regions of a working volume and using that information to delay volume initialization Various embodiments of systems and methods are disclosed for tracking valid regions of a working volume. State information identifies which regions of the working volume are currently valid. When the volume is created, the state information can be initialized to a v... | 08/05/2008 |
| 7373543 | Method and apparatus for uninterrupted packet transfer using replication over disjoint paths A method of operating a fault tolerant connection in a network is described. The network includes a number of network elements and a number of links. Each of the network elements is coupled to at least one other of the network elements by at least one of the links. ... | 05/13/2008 |
| 7366969 | System and method for implementing a Reed Solomon multiplication section from exclusive-OR logic Various methods and systems for implementing Reed Solomon multiplication sections from exclusive-OR (XOR) logic are disclosed. For example, a system includes a Reed Solomon multiplication section, which includes XOR-based logic. The XOR-based logic includes an input... | 04/29/2008 |
| 7343485 | System and method for maintaining protocol status information in a network device A method may involve: maintaining protocol status information for a network protocol, where the protocol status information includes protocol information generated by a protocol server and network traffic information indicative of how messages are conveyed from the ... | 03/11/2008 |
| 7313724 | Method and apparatus for synchronizing redundant data with a volume Various embodiments of systems and methods are disclosed for initially synchronizing redundant data (e.g., a mirror, a replica, or a set of parity information) with an original volume. State information identifies which regions of the original volume are currently v... | 12/25/2007 |
| 7310704 | System and method for performing online backup and restore of volume configuration information Various embodiments of systems and methods are disclosed for performing online backup and restore of volume configuration information.

| 7217889 | System and method for reducing crosstalk between vias in a printed circuit board Two pairs of vias are arranged in a printed circuit board. A first pair of vias, which conveys a first signal pair, is arranged in a plane that is substantially equidistant from the vias in a second pair of vias, which conveys a second signal pair. Similarly, the se... | 05/15/2007 |
| 7194487 | System and method for recording the order of a change caused by restoring a primary volume during ongoing replication of the primary volume A method may involve replicating a first change made to a primary volume. The first change is replicated to a secondary volume. A second change made to the primary volume is also replicated to the secondary volume. The second change is caused by a restore operation.... | 03/20/2007 |
| 7054960 | System and method for identifying block-level write operations to be transferred to a secondary site during replication A method involves generating a block-level write operation, which causes a value to be written to a primary volume, and generating information indicative of whether any of the block-level write operation should be transferred to a secondary site during replication o... | 05/30/2006 |
