摘要： A method is provided for transmitting user data from a selected one of a plurality of data pipes. The method includes having a ring manager select one of the data pipes from a pool of the data pipes for transmission of the user data. The data is transmitted from the selected one of the data pipes at least one packet switching network. The data pipe detects whether there was an error in the transmission. If there an error detected, the data pipe generates an error interrupt for the ring manager. The ring manager detects the error interrupt and generates an error interrupt for a CPU. The ring manager removes the selected one of the data pipes from the pool of data pipes for a predetermined period of time while the ring manager continues to work on other tasks until the time has expired. During pipe retirement, the physical pipe removed from the pool of pipes is disabled and the router will then direct orphan packets to the error ring. When the time has expired, the ring manager returns the selected data pipe to the pool of available data pipes.

摘要： A data storage system having protocol controller for converting packets between PCIE format used by a storage processor and Rapid IO format used by a packet switching network. The controller includes a PCIE end point for transferring atomic operation (DSA) requests, a data pipe section having a plurality of data pipes for passing user data; and a message engine section for passing messages among the plurality of storage processors. An acceleration path controller bypasses a DSA buffer in the absence of congestion on the network. Packets fed to the PCIE end point include an address portion having code indicating an atomic operation. An encoder converts the code from a PCIE format into the same atomic operation in SRIO format. Each one of a plurality of CPUs is adapted to perform a second DSA request during execution of a first DSA request.

摘要： An end point controller includes two of ingress/egress port pairs. A first one of the ingress/egress ports is adapted to send and receive one of a pair of types of information packets and a second one of the ingress/egress ports is adapted to send and receive the other one of the pair of types of information packets. A controller is coupled to the two port pairs for coupling one of ingress/egress ports to an input/output port selectively in accordance with the type of the information packet on the ingress/egress ports and the availability of the end point controller to a network. One of the egress ports is directly coupled to the output port to the network if the information packet is at such port and the end point controller has been granted access to the network while other information at the pair of egress ports is buffered prior to being coupled to the output. In like fashion, the input port from the network is directly coupled to one of the ingress ports if the information packet is of the type of information packet destined for such ingress port, said port being available to transmit the packet.

摘要： A system interface having: a plurality of front end directors adapted for coupling to a host computer/server; a plurality of back end directors adapted for coupling to a bank of disk drives; a data transfer section having cache memory; a cache memory manager; and, a message network. The cache memory is coupled to the plurality of front end and back end directors. The messaging network operates independently of the data transfer section and is coupled to the plurality of front end and back end. The front end and back end directors control data transfer between the host computer/server and the bank of disk drives in response to messages passing between the front end directors and the back end directors through the messaging network to facilitate data transfer between host computer/server and the bank of disk drives. The data passes through the cache memory in the data transfer section as such data passes between the host computer and the bank of disk drives. The system includes a cache memory manager having therein a memory for storing a map maintaining a relationship between data stored in the cache memory and data stored in the disk drives. The cache memory manager provides an interface between the host computer, the bank of disk drives and the cache memory for determining for the directors whether data to be read from the disk drives, or data to be written to the disk drives, resides in the cache memory. With such an arrangement, the cache memory in the data transfer section is not burdened with the task of transferring the director messaging but rather a messaging network is provided, operative independent of the data transfer section, for such messaging thereby increasing the operating bandwidth of the system interface. Further, the cache memory is no longer burdened with the task of evaluating whether data to be read from the disk drives, or data to be written to the disk drives, resides in the cache memory. The cache memory manager, plurality of front end directors, plurality of back end directors and cache memory are interconnected through a packet switching network.
