Evaluating SP System power requirement
The total power requirement of your RS/6000 SP system is the sum of the power
required by all of the following individual components:
򐂰 Each base frame with integral power subsystem.
򐂰 Each processor node.
򐂰
All options and adapters in each node.
򐂰 Each switch.
򐂰
All auxiliary equipment, such as SP-attached servers, routers, RAIDs,
extension nodes, printers, etc.
For the all auxiliary equipment, see the appropriate equipment documentation.
After calculating frame power requirements, add the total of all auxiliary
equipment power to the total power usage of all the frames in your system.
Notes:
1. Not supported in 120 MHz thin nodes or 135 MHz wide nodes.
2. High nodes and wide nodes have a minimum of one if used.
3. FDDI dual ring adapters (F/C 2723) have a mandatory prerequisite of the
FDDI-SAS
(F/C 2724).
4. The HIPPI feature (F/C 2735) uses three physical MCA slots and requires
a total of five
slots to satisfy power and thermal requirements.
5. The BMCA node-to-node (F/C 2752) cables are required on any node
having the BMCA
adapter and not having an external host connection.
6. BMCA adapters cannot be installed in two adjacent MCA slots due do
physical cabling
constraints. There is a limit of 32 adapters per frame, and a limit
of 16 cables exiting the frame.
7. A maximum of 128 9333 High Performance Subsystem Adapter cables is
allowed per
frame.
8. Will not operate in SSA loops containing F/C 6214 or F/C 6216.
