Lenovo NeXtScale nx360 M5, Installation And Service Manual, Page: 25 / 1022

The compute node supports up to 512 GB of system memory. The memory controller provides support
for up to 16 industry-standard registered ECC DDR4 on low-profile (LP) DIMMs on the system board. For
the most current list of supported DIMMs, see http://www.lenovo.com/ serverproven/.
• Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more information about light
path diagnostics and the LEDs, see “Compute node controls, connectors, and LEDs” on page 18.
• Microprocessor technology
The compute node supports up to two multi-core IntelXeon microprocessors. For more information about
supported microprocessors and their part numbers, see http://www.lenovo.com/ serverproven/.
Note: The optional microprocessors that Lenovo supports are limited by the capacity and capability
of the compute node. Any microprocessor that you install must have the same specifications as the
microprocessor that came with the compute node.
• Mobile access to Lenovo Service Information website
The server provides a QR code on the system service label, which is on the cover of the server, that you
can scan using a QR code reader and scanner with a mobile device to get quick access to the Lenovo
Service Information website. The Lenovo Service Information website provides additional information
for parts installation and replacement videos, and error codes for server support. For the QR code, see
Chapter 1 “The Lenovo NeXtScale nx360 M5 compute node” on page 1.
• PCI Express
PCI Express is a serial interface that is used for chip-to-chip interconnect and expansion adapter
interconnect. You can add optional I/O and storage devices.
Optional expansion nodes are available to provide a cost-effective way for you to increase and customize
the capabilities of the compute node. Expansion nodes support a wide variety of industry-standard PCI
Express, network, storage, and graphics adapters.
• Power throttling
By enforcing a power policy known as power-domain oversubscription, the NeXtScale n1200 Enclosure
can share the power load between twelve power supplies to ensure sufficient power for each device in the
NeXtScale n1200 Enclosure. This policy is enforced when the initial power is applied to the NeXtScale
n1200 Enclosure or when a compute node is inserted into the NeXtScale n1200 Enclosure.
The following settings for this policy are available:
– Basic power management
– Power module redundancy
– Power module redundancy with compute node throttling allowed
• Lenovo XClarity Administrator
Lenovo XClarity Administrator is a centralized resource-management solution that enables administrators
to deploy infrastructure faster and with less effort. The solution seamlessly integrates into System x,
ThinkServer, and NeXtScale servers, as well as the Flex System converged infrastructure platform.
Lenovo XClarity Administrator provides:
– Automated discovery
– Agent-free hardware management
– Monitoring
– Firmware updates and compliance
– Pattern-based configuration management
– Deployment of operating systems and hypervisors
