Abstract

Data transfers from the peripheral interface of a disk array to a data buffer are snooped to determine if the starting address of a data transfer matches an entry in a list of starting addresses for requested data. If a match is identified, third party transfer is initiated and the data is simultaneously transferred to the host interface of the host system. The resulting data bandwidth is increased. A throttling/suspension mechanism can temporarily or indefinitely hold up actual data movement into the data buffer to allow for temporary buffering and interface speed matching as data is transferred to the host interface.
