Latest Patents

One of John O'Shea's latest patents is a method for performing a RAID operation in a data storage system. This innovative system features a protocol controller that converts packets between the PCIE format used by a storage processor and the Rapid IO format utilized by a packet switching network. The controller includes a PCIE endpoint for transferring atomic operation (DSA) requests, a data pipe section with multiple data pipes for passing user data, and a message engine section for communication among various storage processors. An acceleration path controller is designed to bypass a DSA buffer when there is no congestion on the network. The packets sent to the PCIE endpoint contain an address portion that indicates an atomic operation. An encoder is responsible for converting the code from PCIE format into the corresponding atomic operation in SRIO format. Each CPU in the system is capable of executing a second DSA request while a first DSA request is still in progress.

Another significant patent involves a method for transmitting user data from a selected data pipe among several available options. This method employs a ring manager to choose one data pipe from a pool for data transmission. The data is then sent from the selected data pipe through at least one packet switching network. The data pipe is equipped to detect transmission errors and generates an error interrupt for the ring manager if an error occurs. The ring manager subsequently notifies the CPU of the error and temporarily removes the affected data pipe from the pool while continuing to manage other tasks. Once the predetermined time has elapsed, the ring manager reintegrates the data pipe into the pool of available options.
