32 IBM BladeCenter PS703 and PS704 Technical Overview and IntroductionTable 1-13 Converged network modules supported by the QLogic CNAFor the latest interoperability information see the BladeCenter Interoperability Guide,available from:http://ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-50730161.7.5 InfiniBand switch moduleThe Voltaire 40 Gb InfiniBand Switch Module for BladeCenter provides InfiniBand QDRconnectivity between the blade server and external InfiniBand fabrics in non-blockingdesigns, all on a single device. Voltaire's high speed module also accommodatesperformance-optimized fabric designs using a single BladeCenter chassis or stackingmultiple BladeCenter chassis without requiring an external InfiniBand switch.The InfiniBand switch module offers 14 internal ports, one to each server, and 16 ports out ofthe chassis per switch.The module's HyperScale architecture also provides a unique interswitch link or meshcapability to form highly scalable, cost-effective, and low latency fabrics. Because this switchhas 16 uplink ports, they can create a meshed architecture and still have unblocked access todata using the 14 uplink ports. This solution can scale from 14 to 126 nodes and offerslatency of less than 200 nanoseconds, allowing applications to operate at maximumefficiency.The PS703 and PS704 blades connect to the Voltaire switch through the 2-port 40 GbInfiniBand Expansion Card. The card is only supported in a BladeCenter H and the two portsare connected to high speed I/O switch bays 7/8 and 9/10.Details about the Voltaire 40 Gb InfiniBand Switch Module for the BladeCenter H are shownin Table 1-14.Table 1-14 InfiniBand switch module for IBM BladeCenterPartNumberFeatureCodeaa.
