Setting Node Interleaving
You can disable the NUMA architecture properties of the system. All operating systems supported
by this platform support NUMA architectures. In most cases, obtain optimum performance by
disabling Node Interleaving. When this option is enabled, memory addresses are interleaved
across the memory installed for each processor and some workloads might experience improved
performance.
IMPORTANT: Enabling Node Interleaving can impact operating system performance.
To set node interleaving:
1.
From the System Utilities screen, select System Configuration
→BIOS/Platform Configuration
(RBSU)
→Advanced Options→Advanced Performance Tuning Options→ Node Interleaving and
press Enter.
2. Select one of the following options:
•
Enabled—Enabling Node Interleaving requires all nodes to equal memory sizes. System
performance might be impacted.
•
Disabled (default)—In most cases, disabling Node Interleaving provides optimum
performance.
3. Press F10 to accept your selection.
