3.1 Installing the Sun SPARC Solaris Fusion-MPT™ Drivers
The LSI Logic LSI40909G-S offers the highest possible performance on
Sun Solaris systems. The LSI Logic Fusion-MPT FC driver (itmpt) is
optimized for low CPU overhead and high I/O throughput, making use of
the LSI Logic Fusion-MPT architecture.
The LSI Logic FC adapters have built-in Fcode, designed to operate in
the Sun OpenBoot environment, allowing FC devices to be available to
the OpenBoot (
ok ) prompt.
The LSI Logic driver, itmpt, allows the Solaris operating system to
interface with FC devices connected to the LSI40909G-S. This driver
takes advantage of new hardware features in the LSI40909G-S to
minimize CPU utilization, including interrupt coalescing, which can result
in less than one interrupt per I/O.
