Servicing CRUs That Require Server Node Power Off
Each processor in Oracle Database Appliance Version 1 has six DIMM slots numbered D0
through D5. D0 is the closest to the processor and D5 is the farthest.
Each slot should contain a 1333 MHz or 1600 MHz DDR3, 8GB dual rank DIMM. No other
configurations are supported.
The server node supports a maximum memory speed of 1333 MHz, even if it is configured with
1600 MHz DIMMs.
If the system contains a mixture of 1333 MHz and 1600 MHz DIMMs, then P0 and P1 should
be configured the same, so that both sides are symmetrical. For example, if you install only two
1600 MHz DIMMs, they should go into P0, D0 and P1, D0.
The following picture shows the physical layout of the DIMMs and CPUs. When viewing the
server node from the front, CPU0 (P0) is on the right.
Each processor socket supports three independent memory channels labeled channel A, B,
and C, where channel A is closest to the processor socket. Each channel supports two DIMM
slots, is controlled by an independent memory controller, and operates independent of the other
channels.
