Processor Subsystem

The Oracle Server X5-4 uses the Intel Xeon E7-8895 v3 18-core 2.6 GHz processor and supports two CPU-based configurations: a two-CPU configuration and a four-CPU configuration.

Two-CPU Configuration

Servers with two CPUs have CPUs and heatsinks in sockets 0 and 1 and CPU cover plates installed in sockets 2 and 3. This configuration requires four memory riser cards and an air baffle to control airflow for maximum cooling. The following illustration shows the components in a two-CPU server configuration.

Callout Description 1 Air baffle 2 CPU P1 3 CPU P0 4 Memory riser card P1/MR1 5 Memory riser card P1/MR0 6 Memory riser card P0/MR1 7 Memory riser card P0/MR0

Four-CPU Configuration

In addition to four CPUs, this configuration requires eight memory riser cards. The following illustration shows the components in a four-CPU server configuration.

Callout Description Callout Description 1 Memory riser card P3/MR1 7 Memory riser card P0/MR1 2 Memory riser card P3/MR0 8 Memory riser card P0/MR0 3 Memory riser card P2/MR1 9 CPU P3 4 Memory riser card P2/MR0 10 CPU P2 5 Memory riser card P1/MR1 11 CPU P1 6 Memory riser card P1/MR0 12 CPU P0

The four-CPU configuration offers a greater level of resiliency with redundant QPI interconnects that allow working CPUs to route around a disabled CPU as the system starts.
