memory activation feature. One pre-planned memory acti-
vation feature is required for each preplanned memory fea-
ture. You now have the fl exibility to activate memory to any
logical size offered between the starting and target size.
Plan ahead memory is exclusive to System z10 and is
transparent to operating systems.
Service Enhancements
z10 EC service enhancements designed to avoid sched-
uled outages include:
• Concurrent fi rmware fi xes
• Concurrent driver upgrades
• Concurrent parts replacement
• Concurrent hardware upgrades
• DIMM FRU indicators
• Single processor core checkstop
• Single processor core sparing
• Point-to-Point SMP Fabric (not a ring)
• FCP end-to-end checking
• Hot swap of ICB-4 and Infi niBand hub cards
• Redundant 100 Mb Ethernet service network with VLAN

Environmental Enhancements

Power and cooling discussions have entered the budget
planning of every IT environment. As energy prices have
risen and utilities have restricted the amount of power
usage, it is important to review the role of the server in bal-
ancing IT spending.
Power Monitoring
The "mainframe gas gauge" feature introduced on the
System z9 servers, provides power and thermal informa-
tion via the System Activity Display (SAD) on the Hardware
Management Console and will be available on the z10
EC giving a point in time reference of the information. The
current total power consumption in watts and BTU/hour as
well as the air input temperature will be displayed.
Power Estimation Tool
To assist in energy planning, Resource Link provides tools
to estimate server energy requirements before a new
server purchase. A user will input the machine model,
memory, and I/O confi guration and the tool will output
an estimate of the system total heat load and utility input
power. A customized planning aid is also available on
Resource Link which provides physical characteristics
of the machine along with cooling recommendations,
environmental specifi cations, system power rating, power
plugs/receptacles, line cord wire specifi cations and the
machine confi guration.
