Operating System-Specific Settings In Uefi; Creating An Hx5 Scalable Complex - IBM System x3850 X5 Implementation Manual

Use these general settings for each operating system type:
Pooled: Use this setting with Linux operating systems.
Non-Pooled: VMware and Microsoft operating systems must be configured to use the
Non-Pooled setting.

8.5.6 Operating system-specific settings in UEFI

When installing an operating system onto an HX5, there is little that you are required to
configure in the UEFI. When using MAX5, ensure that you follow the MAX5 memory scaling
settings that are described in 8.7, "Operating system installation" on page 407.

8.6 Creating an HX5 scalable complex

The HX5 provides the flexibility to scale from a single-node 2-socket system to a dual-node
4-socket system, and back again when the business demand requires it. You can achieve all
of this scaling without having to make any physical changes to the hardware after the
scalability kit has been installed. The configuration of a multinode HX5 is controlled through
the AMM web interface. The AMM communicates with the onboard integrated management
module (IMM) to enable and disable the scaling capabilities of the system, allowing for great
flexibility.
In this section, we demonstrate how to scale two single-node HX5s into a dual-node complex.
Firmware requirements: Before you attempt to scale the HX5, see Table 8-3 on page 380
for the minimum firmware requirements for the HX5 and the AMM.
Use the following steps to create a complex:
1. Log in to the AMM.
2. Navigate to Scalable Complex  Configuration. The scalable systems and the slots
that they occupy are shown as tabs, as shown in Figure 8-36 on page 403. For our
example, we use the HX5s installed in blade bays 1 and 2 to create a partition.
