摘要： Provided are a computer program product, system, and method for selecting Direct Memory Access (DMA) engines in an adaptor for processing Input/Output requests received at the adaptor. A determination is made of an assignment of a plurality of processors to the DMA engines, wherein each processor is assigned to use one of the DMA engines. I/O request related work for a received I/O request directed to the storage is processed by determining the DMA engine assigned to the processor processing the I/O request related work and accessing the determined DMA engine to perform the I/O related work.

摘要： A first adaptor implements a first communication protocol and a second adaptor implements a converged network protocol, which facilitates communication of packets encoded with a second communication protocol with a third communication protocol network. Parameters are configured in a memory for communication between the first adaptor and the second adaptor in the converged network protocol to indicate to the second adaptor that the converged network protocol is supported, wherein the first adaptor does not support the converged network protocol. A packet is received at the first adaptor encoded in the second communication protocol and forwarded to the second adaptor to forward to the third communication protocol network. A command is received at the second adaptor, directed to the first adaptor, to implement a function in the converged network protocol using the parameters in the memory to support transmission of packets between the first and the second adaptors.

摘要： An apparatus, system, and method are disclosed for establishing a point-to-point connection using Fibre Channel over Ethernet (FCoE). The point-to-point connection is established as part of the FCoE Initialization Protocol (FIP). A first computing device sends a FIP discovery solicitation to a predefined address such as ALL-FCF-MACs. The first computing device also listens to the local ALL-FCF-MACs address and determines whether or not there are any switches in the fabric connecting the first computing device and the second computing device. If there are no switches, the first computing device sends a second FIP discovery solicitation with a point-to-point indicator. If the first computing device receives a similar FIP discovery solicitation from the second computing device, it sends a FIP discovery advertisement with the point-to-point indicator. The first computing device and second computing device then perform fabric login and establish a point to point connection.

摘要： A Fiber Channel over Ethernet (FCoE) device obtains knowledge of the configuration of an attached Ethernet fabric from data fields within a frame header during a fabric initialization or login (FLOGI) process. FCoE N_Ports obtain similar information during the port initialization or login (PLOGI) process. The FCoE device may provide network management services to attached FCoE devices. Embodiments include a management module or processor within an FCoE N_Port. The management module or processor receives a frame having a header and validates and extracts information associated with an Ethernet fabric from the FCoE N_Ports and in order to provide management services based on the information associated with the Ethernet fabric. The FCoE N_Port communicatively couples to at least one additional FCoE N_Port through the Ethernet fabric. The FCoE N_Ports may be implemented within a disc storage drive, a host bus adapter, and/or an FCoE switch. The capability of an N_Port to obtain this information allows a management module or processor at the N_Port to manage the Ethernet fabric.

摘要： A method for clearing a fault condition at a target device is disclosed herein. In selected embodiments, such a method includes detecting a fault condition at a target device and receiving N instructions before the fault condition is cleared, where the N instructions are unexecutable due to the fault condition. N fault condition indicators are transmitted in response to the N instructions. Clearing of the fault condition is detected when the fault condition no longer exists. Acknowledgments corresponding to the fault condition indicators are received, where each acknowledgment indicates that one of the fault condition indicators has been received. A fault clear indicator is transmitted only after both all N fault condition indicators have been received and clearing of the fault condition has been detected. A corresponding system and computer program product are also disclosed herein.

摘要： Provided are a computer program product, system, and method for a bridge for implementing a converged network protocol to facilitate communication between different communication protocol networks. A first adaptor implements a first communication protocol and a second adaptor implementing a converged network protocol, wherein the converged network protocol facilitates communication of packets encoded with a second communication protocol with a third communication protocol network. Parameters are configured in a memory for communication between the first adaptor and the second adaptor in the converged network protocol to indicate to the second adaptor that the converged network protocol is supported, wherein the first adaptor does not support the converged network protocol. A packet is received at the first adaptor encoded in the second communication protocol directed to the third communication protocol network. The packet is forwarded to the second adaptor to forward to the third communication protocol network. A command is received at the second adaptor, directed to the first adaptor, to implement a function in the converged network protocol for communication between the first and second adaptors. Operations are performed to implement the function using the parameters in the memory to support transmission of packets between the first and the second adaptors.
