What Your Compute Node Offers - Lenovo NeXtScale nx360 M4 Installation And Service Manual

• Airborne particulates and reactive gases acting alone or in combination with other environmental
factors such as humidity or temperature might pose a risk to the compute node. For information
about the limits for particulates and gases, see "Particulate contamination" on page dccx.
Notes:
1. Onboard LSI software SATA RAID supports SATA drives and Solid state drives (SSD). SAS drives are not
supported for software RAID. The booting and use of internal drives with VMware is not supported with
the ServeRAID C100 (software RAID) controller.
2. Chassis is powered on.
3. A3 - Derate maximum allowable temperature 1°C/175 m above 950 m.
4. The minimum humidity level for class A3 is the higher (more moisture) of the -12°C dew point and the
8% relative humidity. These intersect at approximately 25°C. Below this intersection (~25°C), the
dew point (-12°C) represents the minimum moisture level; above the intersection, relative humidity
(8%) is the minimum.
5. Moisture levels lower than 0.5°C DP, but not lower -10 °C DP or 8% relative humidity, can be accepted if
appropriate control measures are implemented to limit the generation of static electricity on personnel
and equipment in the data center. All personnel and mobile furnishings and equipment must be
connected to ground via an appropriate static control system. The following items are considered
the minimum requirements:
a. Conductive materials (conductive flooring, conductive footwear on all personnel who go into the
datacenter; all mobile furnishings and equipment will be made of conductive or static dissipative
materials).
b. During maintenance on any hardware, a properly functioning wrist strap must be used by any
personnel who contacts IT equipment.
6. 5°C/hr for data centers employing tape drives and 20°C/hr for data centers employing disk drives.
7. Chassis is removed from original shipping container and is installed but not in use, for example, during
repair, maintenance, or upgrade.
8. The equipment acclimation period is 1 hour per 20°C of temperature change from the shipping
environment to the operating environment.
9. Condensation, but not rain, is acceptable.

What your compute node offers

Your compute node offers features such as the integrated management module II, hard disk drive support,
systems-management support, microprocessor technology, integrated network support, I/O expansion,
large system-memory capacity, light path diagnostics LEDs, PCI Express, and power throttling.
• Features on Demand
If a Features on Demand feature is integrated in the compute node or in an optional device that is installed
in the compute node, you can purchase an activation key to activate the feature. For information about
Features on Demand, see /http://www.ibm.com/systems/x/fod/.
• Flexible network support
The compute node provides flexible network capabilities:
– Models with embedded Ethernet
The server comes with an integrated dual-port Intel Gigabit Ethernet controller, which supports
connection to a 10 Mbps, 100 Mbps, or 1000 Mbps network.
– Models without embedded Ethernet
The compute node has connectors on the system board for optional expansion adapters for adding
network communication capabilities to the compute node. This provides the flexibility to install
expansion adapters that support a variety of network communication technologies.
• Hard disk drive support
