New Features and Enhancements
The new features and enhancements added since Release 7.0 and the two
previous major/minor releases for the OFED+ Host Software are listed below.
Release 7.0.1 Features
 The iba_manage_switch script, along with the xedge tools, is included as
part of IB-Basic (OFED+) allowing customers not using the IFS software to
manage externally managed switches. Unlike FastFabric, it is designed to
operate on one switch at a time, taking a mandatory target GUID parameter.
Refer to the QLogic OFED+ Host Software User Guide for more information.
 Performance tuning parameters for the QLE7340 and QLE7342 drivers can
now be set on a per port or per unit basis. If there are two Host Channel
Adapters in a server, settings for one Host Channel Adapter can be
optimized for storage traffic and settings for the other Host Channel Adapter
can be optimized for MPI traffic. Please see the QLogic OFED+ Host
Software User Guide for details.
Release 7.0 Features
 The automatic performance tuning utility: ipath_perf_tuning can be run
as root to set the qib driver parameters in the modprobe.conf file. The
utility can be run without parameters to do a minimal, safe amount of tuning,
or the OFED+ Host Software User Guide describes how to run the utility
interactively to tune node performance for more situations, such as to
improve parallel storage performance, or to turn off unneeded services.
 The QLogic Congestion Control Architecture (CCA) uses the Performance
Scaled Messaging (PSM) library which is included within QLogic OFED+.
The QLogic Fabric Manager is required to enable and manage QLogic CCA.
For information about QLogic CCA, refer to the “Fabric Manager Features,
Release 7.0” section in the QLogic InfiniBand Fabric Suite Software Release
Notes and the QLogic Fabric Manager User Guide.
