E870/880 Racking - “Only Enterprise 42U Rack” Only the IBM Enterprise rack (7014-T42 or #0553)
have been tested/certified by IBM Development/Test with the E870/E880 as of Oct 2014. Therefore the 7014-T42 or #0553 is the only rack IBM Manufacturing uses withE870/E880 system nodes.
If a different rack (IBM or non-IBM) is desired, work with IBM Service organization to confirm the rack has the needed strength, rigidity, hole spacing, clearances, etc. IBM Service does not require certification by IBM Development/Test to be able to provide service/warranty in other racks.

Capacity on Demand (CoD) (1 of 2)
Static CoD : Activations are permanent Not eligible to be relocated
Mobile CoD Activations are permanent Eligible to be relocated (within defined enterprise pool)
Elastic (On/Off) CoD Activations are temporary Not eligible to be relocated. Covers 24 hours from activation time
Utility Almost similar to Elastic Processor minute is charged
Power IFLs For use in Linux partitions only Activations are permanent Not eligible to be relocated
Capacity on Demand (CoD) (1 of 2)
POWER Enterprise Pool
Dynamically move processor and memory activations between systems within a defined pool
Require Mobile features of Capacity of Demand (CoD) Supported platform : 770, 780, 795, E870 and E880 Mix processor generation within pool type Applications:
LPM : Partition relocation, mobile activations shifted between LPM servers
PowerHA : When primary server fails, move mobile activations to backup server
Rebalance server capacity: Mobile activation moved between servers to make best use of CPU core and memory resources
POWER Enterprise Pool (PEP)- Configuration compliance Single server can be member of only one Power
Enterprise Pool at a time Customers must complete both PEP agreements Server must join a POWER Enterprise Pool type based
on its processor class of system Mid Range : 770 and E870 High Range : 780, 795 and E880
Each pool will tie to only one master HMC that manages all its resources
Master HMC holds the key All HW & SW maintenance coverage must be
consistent
