The QHT7140 has a smaller form factor than the QHT7040, but is otherwise the same. Throughout
this document, the QHT7040 and QHT7140 are collectively referred to as the QHT7140 unless
otherwise noted.
Single port 10Gbps SDR 4X InfiniBand to HTX adapter. For
systems with HTX expansion slots.
QLE7140 Single port 10Gbps SDR 4X InfiniBand to PCI Express x8
adapter. Supported on systems with PCI Express (PCIe) x8 or
x16 slots.
QLE7240 Single port 20Gbps DDR 4X InfiniBand to PCI Express x8
adapter. Supported on systems with PCI Express x8 or
x16 slots.
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.
