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.
