The present disclosure provides a method and system for dynamically migrating a port in a PCIe switch. The PCIe switch comprises emulated P2P bridges stored in a memory and a processor to load the emulated P2P bridge address range values from the memory to a routing table. The processor can configure the routing table so that the P2P bridges can be remapped to various physical ports of the switch. Therefore, a device connected to a physical port may be migrated from one host to another, via the operations of the processor.

System and method for port migration in a PCIE switch

A SAS expander includes a switch core, a number of SAS expander phys coupled to the switch core, an SMP originator coupled to the switch core and an SMP receptor coupled to the switch core. In an embodiment, the SMP originator is configured to only send connection requests and the SMP receptor is configured to only receive connection requests. Program instructions stored in non-transient digital storage media include code segments detecting a new connection request, code segments determining whether the new connection request is in conflict with an existing connection request and code segments determining if there is a free destination receptor phy. In an embodiment, the free destination receptor phy is never operationally used for an origination of a connection request.

SAS expander with non-blocking virtual phy architecture

Various embodiments of the invention provide resource management of available data bandwidth of a SAS system in a non-uniform way. In certain embodiments, arbitration wait time values are adaptively modified to achieve a specified performance quota for a link.

Dynamic resource allocation for serial attached SCSI devices

Various embodiments of the innovation provide adaptive equalization training for a receiver in a communication system. In certain embodiments, the receiver's coefficients are re-optimized while links are active and initialized.
