LSISAS1068 Features

* a performance based message passing protocol that ofﬂoads the host CPU by completely managing all I/Os and minimizes system bus overhead by coalescing interrupts. The Fusion-MPT architecture requires only thin, easy to develop device drivers that are independent of the I/O bus. LSI Logic provides th
