System features – Introduction to Power E1080
1.5 System features
This section lists and explains the available system features on a Power E1080 server. These features describe the resources that are available on the system by default or by virtue of procurement of configurable feature codes.
An overview of various feature codes and the essential information also is presented that can help users design their system configuration with suitable features that can fulfill the application compute requirement. This information also helps with building a highly available, scalable, reliable, and flexible system around the application.
1.5.1 Minimum configuration
A minimum configuration babels a user to order a fully qualified and tested hardware configuration of a Power system with a minimum set of offered technical features. The modular design of a Power E1080 server enables the user to start low with a minimum configuration and scale up vertically as and when needed.
Table 1-5 lists the Power E1080 server configuration with minimal features.

1.5.2 Processor features
Each system node in a Power E1080 server provides four sockets to accommodate Power10 single chip modules (SCMs). Each processor feature code represents four of these sockets, which are offered in 10-core, 12-core, and 15-core density.
Table 1-6 lists the available processor feature codes for a Power E1080 server. The system configuration requires one, two, three, or four quantity of same processor feature, according to the number of system nodes.
Table 1-6 Processor features.
The system nodes connect to other system nodes and to the system control unit through cable connect features. Table 1-7 lists the set of cable features that are required for one-, two-, three-, and four-node configurations.

16 IBM Power E1080: Technical Overview and Introduction
Every feature code that is listed in Table 1-6 on page 16 provides the processor cores, not their activation. The processor core must be activated to be assigned as resource to a logical partition. The activations are offered through multiple permanent and temporary activation features. For more information about these options, see 2.4, “Capacity on-demand” on
page 76.
Table 1-8 lists the processor feature codes and the associated permanent activation features. Any of these activation feature codes can permanently activate one core.
Table 1-8 Processor and activation features
The following types of permanent activations are available:
A minimum of 16 processor cores must always be activated with the static activation features, regardless of the Power E1080 configuration. Also, if the server is associated to a PEP 2.0, a minimum of one base activation is required.
For more information about other temporary activation offerings that are available for the Power E1080 server, see 2.4, “Capacity on-demand” on page 76.
Chapter 1. Introduction to Power E1080 17
Regular and PEP 2.0 associated activations for Power E1080 are listed in Table 1-9. The Order type table column includes the following designations:
