Configuring memory in a RAID controller

摘要

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.
