Abstract: Techniques herein include systems and methods for driver-assisted BAR mapping that virtualize PCI functions, but without virtualizing the storage media itself. Such techniques make use of unused BARs (Base Address Registers) of a master (Operating system-facing) device to gain access to other PCIe logical instances, while still exposing only a single PCIe function (connection or channel) to system software. This technique provides a new concept of logical PCIe device instances through BAR mapping by making use of unused BARs to extend access to any number of PCIe instances or memory-mapped I/O devices behind a master device such that only a single PCIe function is exposed to system software. Embodiments can thus extend access to one or more additional storage devices through one level of BAR indirection. As a result, such techniques and embodiments enable the multiplication of storage capacity and performance through the aggregation of multiple, similar hardware components.

By controlling zoning access and performing discovery one device port at a time, the mechanism transfers access and ownership of the RAID group from one adapter pair to another.
