Support for up to six InfiniBand QDR-CX2 ExpressModules (Oracle part number 4243A) has been added to a Sun Server X2-8 system running Oracle Linux 6.4 (eight socket systems only). The following configuration has been tested:
Sun Server X2-8, eight socket system with 2TB memory
InfiniBand QDR-CX2 ExpressModules in slots: EM0.0, EM0.1, EM1.0, EM2.0, EM3.0, EM3.1 (EM1.1 and EM2.1 left empty).
System SW1.2: SP version 220.127.116.11.c_r82507, BIOS 15020500
Sun Server X2-8 systems running versions of Oracle Linux earlier than 6.4, or with only four sockets, only support a maximum of four InfiniBand QDR-CX2 ExpressModules.
