Abstract:
A SAS expander collects data access information associated with a nexus and determines whether a data prefetch is appropriate. The SAS expander identifies potential data blocks utilizing previous data requests of the nexus. The SAS expander issues a data request to the target for the potential data blocks. The SAS expander stores the potential data blocks within a prefetch cache for future utilization within a data read.
