QLDIRECT
The QLDIRECT driver, coupled with the QLogic Windows 2000 enhanced miniport
driver, provides the following features:
A highly optimized I/O path for normal read and write operations with reduced
CPU utilization and increased parallelization
Failover and failback features to reroute I/O operations to the correct path
NOTE: When the storport driver is loaded, QLdirect is not supported.
Consequently, the failover and failback features are not supported.
This section provides installation instructions for the QLDIRECT driver in an already
installed Windows 2000 operating system. Earlier versions of this operating system
are not supported.
