New Features
The following features are new to the 2.2 release:
Expanded MPI scalability enhancements for PCI Express have been added.
On the QLE7240 and QLE7280, up to 16 dedicated hardware contexts per
node are available. The QHT7140 has eight per node. The QLE7140 has
four per node.
A total of 64 processes on the QLE7240 and QLE7280 are supported when
context sharing is enabled. The QHT7040 and QHT7140 support a total of
32 processes per adapter. The QLE7140 supports a total of 16 processes
per adapter.
This release continues support for multiple high-performance native PSM
Message Passing Interface (MPI) implementations added in the 2.1 release.
(PSM is QLogic’s accelerated library for high performance MPIs). In addition
to QLogic MPI, the currently supported MPI implementations are HP-MPI,
Open MPI, MVAPICH, and Scali. Open MPI provides MPI-2 functionality,
including one-sided operations and dynamic processes. These all offer the
same high performance as QLogic MPI.
Dual PCIe QLogic adapters per node are supported.
Driver support for the QLogic Virtual Network Interface Controller (VNIC) is
provided in this release. The VNIC Upper Layer Protocol (ULP) works in
concert with firmware running on Virtual Input/Output (VIO) hardware such
as the SilverStorm™ Ethernet Virtual I/O Controller (EVIC), providing virtual
Ethernet connectivity for Linux operating systems.
The QLogic InfiniBand Fabric Suite CD is available separately for purchase.
The CD includes FastFabric, the QLogic Subnet Manager (SM), and the
Fabric Viewer GUI for the QLogic SM.
QLE7280 Single port 20Gbps DDR 4X InfiniBand to PCI Express x16
adapter. Supported on systems with PCI Express x16 slots.
The QLE7280 is backward compatible; it can also be used with
PCIe adapters that connect to x8 slots.

The QHT7140 has a smaller form factor than the QHT7040, but is otherwise the same. Throughout
this document, the QHT7040 and QHT7140 will be collectively referred to as the QHT7140 unless
otherwise noted.
