The SAS expander includes a plurality of ports and a route lookup table configured for providing a central resource for routing information for the ports. The SAS expander also includes a plurality of connection history caches (CHCs) associated with the ports, each CHC is configured for storing at least one successfully established connection record. Upon receiving a connection request at a particular port, that particular port may determine whether a matching connection record for the connection request is stored in its corresponding CHC. If the matching connection record is stored in its corresponding CHC, a connection may be established in response to the connection request based on the matching connection record. However, if no matching connection record is found in its corresponding CHC, the connection may be established utilizing the route lookup table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Route lookup method for reducing overall connection latencies in SAS expanders","description":"A system and method for reducing overall connection latencies in a SAS expander is disclosed.
