Abstract: Techniques for operating a serial attached SCSI (SAS) expander that includes a latency table comprising entries of outbound PHYS with latency values associated with connections between inbound PHYs and outbound PHYs. A storage management module to, in response to receipt of a command from an initiator device associated with an inbound PHY to route data to a target device associated with an outbound PHY, select from the latency table a random outbound PHY from among a plurality of outbound PHYs, wherein the random selection is based on weighted average of latency values of the outbound PHY entries of the latency table.

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.
