The material in this documentation pertains to an InfiniPath cluster. A cluster is 
defined as a collection of nodes, each attached to an InfiniBand™-based fabric 
through the QLogic interconnect. The nodes are Linux-based computers, each 
having up to 16 processors.

The QLogic HCAs are InfiniBand 4X. The Double Data Rate (DDR) QLE7240 and 
QLE7280 adapters have a raw data rate of 20Gbps (data rate of 16Gbps). For the 
Single Data Rate (SDR) adapters, the QLE7140 and QHT7140, the raw data rate 
is 10Gbps (data rate of 8Gbps). The QLE7240 and QLE7280 can also run in SDR 
mode.

The QLogic adapters utilize standard, off-the-shelf InfiniBand 4X switches and 
cabling. The QLogic interconnect is designed to work with all InfiniBand-compliant 
switches.

If you are using the QLE7240 or QLE7280, and want to use DDR mode, 
then DDR-capable switches must be used.
