Overview

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.

NOTE:

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