IBM Power Systems E870 and E880 Technical Overview and Introduction
Table 2-16 Power Systems Capacity Upgrade on Demand static processor activation features
The Table 2-17 lists the static memory activation features that are available for the
Power E870 and Power E880.
Table 2-17 Power Systems Capacity Upgrade on Demand static memory activation features
2.4.2 Power enterprise pools and mobile capacity on demand (Mobile CUoD)
While static activations are valid for a single system, some customers could benefit from
moving processor and memory activations among different servers due to workload
rebalance or disaster recovery.
IBM power enterprise pools, is a technology for dynamically sharing processor and memory
activations among a group (or pool) of IBM Power Systems servers. Using Mobile Capacity on
Demand (CoD) activation codes, the systems administrator can perform tasks without
contacting IBM.
Two types of power enterprise pools are available:
Power 770 (9117-MMD) and Power E870 (9119-MME) class systems
Power 780 (9117-MHD), Power 795 (9119-FHB), and Power E870 (9119-MHE) class
systems
Each pool type can support systems with different clock speeds or processor generations.
The basic rules for the Mobile Capacity on Demand follows:
The Power 770 and Power 780 systems require a minimum of four static processor
activations.
The Power 870 and Power 880 require a minimum of eight static processor activations.
The Power 795 requires a minimum of 24 static processor activations or 25% of the
installed processor capacity whichever is bigger.
For all systems, 25% of the installed processor capacity must have static activations.
All the systems in a pool must be managed by the same HMC or by the same pair of
redundant HMCs. If redundant HMCs are used, the HMCs must be connected to a network so
that they can communicate with each other. The HMCs must have at least 2 GB of memory.
An HMC can manage multiple power enterprise pools and can also manage systems that are
not part of a power enterprise pool. Systems can belong to only one power enterprise pool at
a time. Powering down an HMC does not limit the assigned resources of participating
systems in a pool but does limit the ability to perform pool change operations.
