Figure 11: Memory Channels
Memory Modes of Operation
Depending on your DIMM configuration, the server can operate in one of the following
modes:
■ Single-channel mode
This is the minimum possible DIMM configuration. The system will automatically
switch to this mode if only DIMM_A1 is populated.
Note: this single DIMM mode operation is not
recommended for “performance” applications.
■ Dual-channel mode (maximum interleave mode)
The DIMMs on adjacent channels on each branch are configured for maximum
interleave in order to provide the optimal lock-step operation.
