12 IBM Power 770 and 780 Technical Overview and Introduction
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 (#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 POWER7 processor card feature,
consisting of two single-chip module processors. Each of the POWER7 processors in the
server has a 64-bit architecture, includes six or eight cores on a single-chip module, and
contains 2 MB of L2 cache (256 KB per core), 24 MB of L3 cache (4 MB per core) for the
6-core SCM, and 32 MB of L3 cache (4 MB per core) for the 8-core SCM.
There are two types of Power 770 processor cards, offering the following features:
򐂰 Two 6-core POWER7 SCMs with 24 MB of L3 cache (12-cores per processor card, each
core with 4 MB of L3 cache) at 3.72 GHz (#4983)
򐂰 Two 8-core POWER7 SCMs with 32 MB of L3 cache (16-cores per processor card, each
core with 4 MB of L3 cache) at 3.3 GHz (#4984)
The Power 780 has two types of processor cards. One of these has two different processing
modes (MaxCore and TurboCore).
1x Removable Media Device
(#5762)
Optionally orderable, a standalone system (not network
attached) requires this feature.
1x HMC Required for every Power 780 (9179-MHC)
Note the following considerations:
򐂰 A minimum number of four processor activations must be ordered per system.
򐂰 The minimum activations ordered with all initial orders of memory features #5600, #5601, and
#5602 must be 50% of their installed capacity.
򐂰 The minimum activations ordered with MES orders of memory features #5600, #5601, and #5602
will depend on the total installed capacity of features #5600, #5601, and #5602. This allows
newly ordered memory to be purchased with less than 50% activations when the currently
installed capacity exceeds 50% of the existing features #5600, #5601, and #5602 capacity.
򐂰 The minimum activations ordered with all initial orders of memory feature #5564 must be 192 GB
of 256 GB per each feature #5564 ordered (that is, 75% of the installed feature #5564 capacity).
򐂰 The minimum activations purchased with MES orders of feature #5564 memory, 0/256 GB, will
depend on the total installed capacity of feature #5564. This allows MES orders of feature #5564
memory to be purchased with less than 192/256 GB per each feature #5564 ordered when the
system activations currently installed exceed 75% of the existing feature #5564 capacity.
