Abstract
Official abstract text for this publication.
According to one aspect, a backplane controller of a storage backplane is disclosed, the storage backplane having a plurality of drive slots configured to operatively connect to a corresponding plurality of mass storage devices. In one embodiment, the backplane controller is operative to perform functions that include detecting activity status on a first serial interface that is configured to operatively connect one or more sets of a plurality of drive slots on the storage backplane to a host bus adapter (HBA), according to a first drive slot assignment. The backplane controller is further operative to detect an activity status on a second serial interface that is configured to operatively connect one or more sets of a plurality of drive slots on the storage backplane to the HBA, according to a second drive slot assignment. The backplane controller is also operative to, if a change in the activity status is detected for at least one of the first serial interface and the second serial interface, modify the first drive slot assignment and the second drive slot assignment.
First claim
Opening claim text (preview).
What is claimed is: 1. A backplane controller of a storage backplane having a plurality of drive slots configured to operatively connect to a corresponding plurality of mass storage devices, the backplane controller operative to perform functions comprising: (a) detecting whether data are actively communicated between a host bus adapter (HBA) and the storage backplane through a first general purpose input/output (SGPIO) interface coupled with the HBA, wherein the first SGPIO inter…
