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

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.
