The following table lists the system specifications.

The System x3650 M5 supports up to two processors of the Intel Xeon processor E5-2600 v4 product family. Also, support for the Intel Xeon processor E5-2600 v3 product family is available via CTO only. The following tables list the specifications of the processors for the System x3650 M5.

For System x3650 M5 server models that come standard with one processor, the second processor can be ordered, if required (see the following table for ordering information). The second processor must be of the same model as the first processor. The second processor option includes two system fans.

* The first feature code is for the first processor; the second feature code is for the second processor.

The System x3650 M5 supports TruDDR4 memory. TruDDR4 memory uses the highest-quality components sourced from Tier 1 DRAM suppliers and only memory that meets strict requirements is selected. It is compatibility tested and tuned on every System x server to maximize performance and reliability.

TruDDR4 memory has a unique signature programmed into the DIMM, which enables System x servers to verify whether the memory installed is qualified and supported. Because TruDDR4 memory is authenticated, certain extended memory performance features can be enabled to extend performance over industry standards. From a service and support standpoint, System x memory automatically assumes the system's warranty, and service and support provided worldwide.

The System x3650 M5 supports up to 12 DIMMs with one processor and up to 24 DIMMs when two processors are installed. Each processor has four memory channels, and there are three DIMMs per channel.

The following rules apply when selecting the memory configuration:

• The server supports RDIMMs and LRDIMMs.
• Mixing different types of memory (RDIMMs and LRDIMMs) is not supported.
• All DIMMs in the server operate at the same speed, which is determined as the lowest value of:
  • Memory speed that is supported by the specific processor.
  • Memory speed for selected quantity of DIMMs per channel.
  Note: Maximum memory speed can be achieved when Max performance mode is enabled in UEFI.

Chipkill works only in independent channel mode (the default operational mode) and supports only x4-based memory DIMMs.

If memory mirroring is used, then DIMMs must be installed in pairs (a minimum of one pair per each processor), and both DIMMs in a pair must be identical in type and size.

If memory rank sparing is used, then a minimum of one quad-rank DIMM or two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need being identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs installed.

Chipkill, memory mirroring, and memory rank sparing modes are mutually exclusive. Only one operational memory mode can be enabled on a server, and it is a system-wide setting.

System x engineering tested and validated system designs that support memory speeds beyond Intel memory specifications, which provides benefits for workloads that require memory speed and density. System x TruDDR4 memory is fully supported up to the rated speeds that are shown in the following table. Table cells highlighted with a gray background indicate when the DIMMs are allowed to operate at a higher speed than Intel specifications define.

* Maximum memory capacity is achieved with two processors installed. With one processor, the capacity is a half of what is shown.

Integrated Management Module 2.1

The System x3650 M5 server contains Integrated Management Module II (IMM2.1), which provides advanced service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM2.1 lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. Optionally, the IMM2.1 also provides a virtual presence capability for remote server management capabilities.

The blue-screen capture feature captures the video display contents before the IMM2.1 restarts the server when the IMM2.1 detects an operating system hang condition. A system administrator can use the blue-screen capture to assist in determining the cause of the hang condition.

Light path diagnostics

All System x3650 M5 server models include basic light path diagnostics, which provides the system LEDs on the front of the server (see Components and connectors) and the LEDs near the monitored components (for example, the DIMM error LED on the system board).

Server models with 8x 3.5-inch or 8x or 16x 2.5-inch front drive bays support a next-gen light path diagnostics LCD display panel (standard on 8x 3.5-inch models; available as an option for 8x or 16x 2.5-inch models). With LCD display, you have quick access to system status, firmware, network, and health information.

Storage dense server models (models with USB ports and system LEDs that are located on the right EIA bracket) with 8x or 16x 2.5-inch front drive bays that are upgradeable to 24x 2.5-inch front drive bays and models with 12x 3.5-inch front drive bays do not support an LCD display panel.

Lenovo XClarity Administrator is an optional software component for the System x3650 M5 which can be downloaded and used at no charge to discover and monitor the x3650 M5 and manage firmware upgrades for them.

If software support is required for Lenovo XClarity Administrator, or Lenovo XClarity Administrator premium features (such as configuration management and operating system deployment) are required, or both, Lenovo XClarity Pro software subscription should be ordered. Lenovo XClarity Pro is licensed on a per managed system basis, that is, each managed Lenovo system requires a license.
