Table Notes
PCIe is Gen 1
aThe 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.
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
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.
