Remapping routing information entries in an expander

摘要

A system includes a peripheral device and an expander having interfaces to couple to one or more peripheral devices and an expander. The expander has a storage to store entries containing routing information used to route a request received by the expander to one of the interfaces, wherein each interface is allocated to a respective set of routing information entries. Mapping logic remaps unused routing information of one of the interfaces to one or more other interfaces to expand capacity of the one or more other interfaces.
