Abstract: Provide access to storage resources of a storage device over a data storage fabric. Allow a zone manager of a first switch to assign a zone group to one of a plurality of phys of an expander of the storage device to allow the first switch to access storage resources of the storage device. If status of the phy that is assigned a zone group indicates a disconnection condition with the first switch, then configure the zone group of the expander of the storage device to prevent access to the storage resources of the storage device. If after the disconnection condition, the status of the phy indicates a reconnection condition with a second switch, then allow a zone manager of the second switch to assign a zone group to the phy to allow the second switch to access storage resources of the storage device.

Abstract: Example embodiments relate to providing serial ATA (SATA) initiator addressing and storage device slicing. In example embodiments, an expander device configures an initiator serial attached SCSI (SAS) address to uniquely identify a SATA initiator, where the SATA initiator is associated with a target address of a SATA storage bridge. Further, the STP storage bridge of the expander device is configured to associate the initiator SAS address with a drive slice of an SATA storage device. At this stage, the expander device receives a SATA request from the SATA initiator, where the SATA request comprises a SATA command and a logical block addressing (LBA) address, and after inserting the initiator SAS address into the SATA request, sends an STP connection request to the target address. The expander device may then offset the LBA address based on the initiator SAS address to obtain an offset LBA address of the SATA storage device.

Abstract: An example disclosed is directed to a switch. The switch includes a communication interface and a discovery module. The discovery module is to receive a registration request for bulk discovery from an initiator device via the communication interface. The discovery module is further to receive a change indication specifying that a change has occurred in a fabric associated with the switch, and update a data model based on the received change indication to generate an updated data model. The discovery module then filters the updated data model to generate a filtered data model, and sends the filtered data model to the initiator device via the communication interface.
