1.4.4 Power supply features
Two system AC power supplies are required for each CEC enclosure. The second power
supply provides redundant power for enhanced system availability. To provide full redundancy,
the two power supplies must be connected to separate power distribution units (PDUs).
A CEC enclosure will continue to function with one working power supply. A failed power
supply can be hot-swapped but must remain in the system until the replacement power supply
is available for exchange. The system requires one functional power supply in each CEC
enclosure to remain operational.
Each Power 770 or Power 780 server with two or more CEC enclosures must have one Power
Control Cable (FC 6006 or similar) to connect the service interface card in the first enclosure
to the service interface card in the second enclosure.
1.4.5 Processor card features
Each of the four system enclosures contains one powerful processor EPH0 card
feature, consisting of four single-chip module processors. Each of the processors
in the server has a 64-bit architecture.
The Power 770 has two types of processor cards, offering the following features:
򐂰
Four 3-core SCMs with 120 MB of L3 cache (12-cores per processor card,
each core with 10 MB of L3 cache) at 4.22 GHz (FC EPM0)
򐂰 Four 4-core SCMs with 160 MB of L3 cache (16-cores per processor card,
each core with 10 MB of L3 cache) at 3.72 GHz (FC EPM1)
The Power 780 has two types of processor cards (note that the TurboCore feature is no
longer offered on 780):
򐂰
Four 4-core SCMs with 160 MB of L3 cache (16-cores per processor card,
each core with 10 MB of L3 cache) at 4.42 GHz (FC EPH0)
򐂰 Four 8-core SCMs with 320 MB of L3 cache (32-cores per processor card,
each core with 10 MB of L3 cache) at 3.72 GHz (FC EPH2)
1x Removable Media Device
(FC 5771) Optionally orderable, a stand-alone system (not network
attached) requires this feature.
1x HMC Required for every Power 780 (9179-MHD)
Considerations:
򐂰 A minimum number of four processor activations must be ordered per system.
򐂰
The minimum activations ordered with MES orders of memory features EM40, EM41, EM42, and
EM44 depend on the total installed capacity of features EM40, EM41, EM42, and EM44. This
allows newly ordered mem ory to be purchased with less than 50% activations when the currently
installed capacity exceeds 50% of the existing features EM40, EM41, EM42 and EM44 capacity.
򐂰 The minimum activations ordered with all initial orders of memory features EM40, EM41, EM42,
and EM44 must be 50% of their installed capacity.
