Abstract

See full text

An HBA driver manages a queue number for enqueuing and dequeuing data to an I/O queue by the main storage, and HBA-F/W manages a storage region at inside of HBA. The HBA driver reduces the number of access times by way of the PCIe bus by noticing an enqueued queue number or a dequeued queue number of an I/O queue to HBA-F/W by utilizing an MMIO area of the main storage in which a storage region on HBA is mapped.
