摘要:
A computational device allocates a plurality of solid state disks to a plurality of redundant array of independent disk (RAID) ranks, wherein a different solid state disk is absent in each RAID rank of the plurality of RAID ranks. The computational device determines at least one selected solid state disk from the plurality of solid state disks, wherein the at least one selected solid state disk is estimated to have undergone a greater amount of wear in comparison to other solid state disks in the plurality of solid state disks. Relatively more data and parity information is written to those RAID ranks in which the at least one selected solid state disk is absent in comparison to those RAID ranks in which the at least one selected solid state disk is present.

A first interconnect card is configured, wherein a first controller is included in the first interconnect card. A second interconnect card coupled to the first interconnect card is configured, wherein a second controller is included in the second interconnect card. In response to a failure of the first controller included in the first interconnect card, the first interconnect card is controlled via the second controller included in the second interconnect card. In response to a failure of the second controller included in the second interconnect card, the second interconnect card is controlled via the first controller included in the first interconnect card.

Provided are a method, system, and program for an adaptor to read and write to system memory. A plurality of blocks of data to write to storage are received at an adaptor. The blocks of data are added to a buffer in the adaptor. A determination is made of pages in a memory device and I/O requests are generated to write the blocks in the buffer to the determined pages, wherein two I/O requests are generated to write to one block split between two pages in the memory device. The adaptor executes the generated I/O requests to write the blocks in the buffer to the determined pages in the memory device.

One embodiment of an adapter card in accordance with the invention includes a circuit board connectable to a motherboard of a computer system. A logic chip is connected to the circuit board to provide functionality to the adapter card. One or more programmable devices are connected to the circuit board and store data read by the logic chip upon initialization. This data may include first character data to program the logic chip to have a first character and second character data to program the logic chip to have a second character. A switching mechanism is provided to switch between the first and second character data in response to an external input, thereby causing the logic chip to read one of the first and second character data.

Protocol multiplexer is configured to receive multiple communication links, each link operating with one of a plurality of communication protocols. Protocol handler converts the received data and frames the data according to the communication protocol in use for a particular communication link. Port multiplexer separates the received frames into data frames and control frames. The data frames being multiplexed onto a single data bus and the control frames being multiplexed onto a single control bus to increase performance of the protocol multiplexer.

A system and method for recording trace data while conserving cache resources includes generating trace data and creating a cache line containing the trace data. The cache line is assigned a tag which corresponds to an intermediate address designated for processing the trace data. The cache line also contains embedded therein an actual address in memory for storing the trace data, which may include either a real address or a virtual address. The cache line may be received at the intermediate address and parsed to read the actual address. The trace data may then be written to a location in memory corresponding to the actual address. By routing trace data through a designated intermediate address, CPU cache may be conserved for other more important or more frequently accessed data.

A method, apparatus and program storage device for automatically presenting status from a host bus adapter until an error is detected is provided. Data is transmitted between the host bus adapter and a host. The host performs data transmission validation and determines whether data transmission was successful. The host bus adapter automatically sends status information when data transmission was successful, else the host bus adapter waits for status type identification from the host for transmission of data.
摘要:
An apparatus, system, and method are disclosed for adapter card failover. A switch module connects a first processor complex to an adapter card through a first port as an owner processor complex. The owner processor complex manages the adapter card except for a second port and receives error messages from the adapter card. The switch module further connects a second processor complex to the adapter card through the second port as a non-owner processor complex. The non-owner processor complex manages the second port. A detection module detects a failure of the first processor complex. A setup module modifies the switch module to logically connect the second processor complex to the adapter card as the owner processor complex and to logically disconnect the first processor complex from the adapter card in response to detecting the failure.
