Abstract: PROBLEM TO BE SOLVED: To solve the problem that a cache memory cannot be automatically constituted in a suitable stripe size and regulating characteristics, when the cache memory is separated from a virtual RAID controller.
SOLUTION: An apparatus has an operable memory together with the virtual RAID controller for deciding an optimum I/O constitution by testing the performance characteristics of a plurality of I/O operations. The I/O operation includes writing of a data block in the RAID controller. The I/O constitution includes data length and data adjustment.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that a cache memory cannot be automatically configured with appropriate stripe size and alignment characteristics if the cache memory is separated from a virtualized RAID controller. SOLUTION: An apparatus has a memory operable with a virtualized RAID controller to determine an optimum I/O configuration by testing performance characteristics of a plurality of I/O operations, wherein the I/O operations include respectively writing a data block in the RAID controller, and the I/O configuration includes data length and data adjustment.

Abstract: An apparatus and method of use are provided to determine the optimum I/O configuration of a RAID controller. The I/O configuration includes parameters for data length and alignment. In use a virtualised RAID controller is established in a memory and tests performance characteristics by issuing a plurality of different I/O operations, each of which includes a write operation to the RAID controller. In response to the testing an optimal configuration can then be set for the RAID controller. Preferably the key performance characteristic may be response time. The memory used maybe cache, an input buffer or and output buffer. The method may be carried out when the RAID controller is idle.

Abstract: A communications control unit, integrated into a processor, enables lines and modems to be changed or replaced by different types of lines and modems without changing the control unit hardware. A common modem adapter design can be used in the control unit for different data rates. A processor microprogram and a simple control unit local microprogram (dynamically changeable during the transfer of data) obviate the need for different adapters for each line and modem type. Both microprograms cooperate to control data transfer.
