The high-speed switch can replace the optional secondary Ethernet switch. It
requires a Myrinet PCI adapter in each cluster node and storage node.
Myrinet BladeCenter connectivity
Myrinet BladeCenter connectivity support includes a Myrinet PCI card, the Optical
Pass thru Module, an I/O expansion card, and special cable options.
Power distribution unit (PDU)
Each rack contains one or more of the following power distribution units:
v
IBM NetBAY Rack Power Distribution Unit (PDU)
v
IBM NetBAY Front-End PDU
v
IBM Distributed Power Interconnect (DPI
®
) Rack PDU
v IBM DPI Front-End PDU
v
IBM DPI High Density PDU
Some PDUs are mounted sideways beside the rack space. The cluster supports rack
PDUs and front-end PDUs. The cluster can have the PDUs installed in the side
pockets and not accessible from the rear. Some of the newer cluster configurations
provide access to the PDUs from the rear of the system cabinet.
Rack PDUs provide power to components within a cabinet; front-end PDUs
provide the connection to the external power source and distribute the power
among the rack PDUs. To eliminate the need for the front-end PDU, a rack PDU is
directly connected to the external power source. Up to four front-end PDUs and up
to 12 rack PDUs can be placed in each cabinet.
