US Patent:

20080034147, Feb 7, 2008

Filed:

Aug 1, 2006

Appl. No.:

11/496858

Inventors:

Robert Stubbs - Longmont CO, US
John Kloeppner - Buhler KS, US
Dennis Gates - Wichita KS, US

International Classification:

G06F 13/36

US Classification:

710315

Abstract:

A method, system and computer program for transferring packets between devices connected to a PCI-Express bus of a computer. A selected pair of devices, such as for example a root complex device and an endpoint device or a pair of endpoint devices, connected to the PCI-Express bus, are configured to transmit/receive data with their respective maximum payload size (MPS). A packet, such as for example a read completion packet, a write memory packet or a message request packet, can then be transmitted from the source device to the destination device. If the source device MPS exceeds the destination device MPS, the packet can be divided into a plurality of sub-packets. Each of sub packets has a maxmimum payload size based on the MPS of the destination device. The sub-packets can then be transmitted to the destination device so that the packet can be delivered to the destination device.

Abstract:

Methods and apparatus for improved calculation of redundancy information in RAID storage controllers. Features and aspects hereof provide for a firmware/software element (FPE) for generating redundancy information in combination with a custom logic circuit (HPE) designed to generate redundancy information. A scheduler element operable on a processor of a storage controller along with the FPE determines which of the FPE and HPE is best suited to rapidly complete a new redundancy computation operation and activates or queues the new operation for performance by the selected component.
