		ASIC ROHS
HT-460	QHT7040	Single Port 10GBS InfiniBand to HTX Adapter
HT-465	QHT7140	Single Port 10GBS InfiniBand to HTX Adapter
PE-880	QLE7140	Single Port 10GBS InfiniBand to x8 PCI Express
		Adapter
PE-850	QMI7140	Single Port 10GBS InfiniBand IBM Blade Center
		Adapter

This version of InfiniPath provides support for all QLogic’s HCAs, including:

■InfiniPath QLE7140, which is supported on systems with PCIe x8 or x16 slots

■InfiniPath QMI7140, which runs on Power PC systems, particularly on the IBM® BladeCenter H processor blades

■InfiniPath QHT7040 and QHT7140, which leverage HTX™. The InfiniPath QHT7040 and QHT7140 are exclusively for motherboards that support HTXcards. The QHT7140 has a smaller form factor than the QHT7040, but is otherwise the same. Unless otherwise stated, QHT7140 will refer to both the QHT7040 and QHT7140 in this documentation.

Expanded MPI scalability enhancements for PCI Express have been added. The QHT7040 and QHT7140 can support 2 processes per context for a total of 16. The QLE7140 and QMI7140 also support 2 processes per context, for a total of 8.
