Features and specifications

Use this information to view specific information about the compute node, such as compute node hardware features and the dimensions of the compute node.

Notes:
  1. Power, cooling, and chassis systems management are provided by the IBM® Flex System chassis.
  2. The operating system in the compute node must provide USB support for the compute node to recognize and use USB media drives and devices. The IBM Flex System chassis uses USB for internal communication with these devices.

The following table is a summary of the features and specifications of the IBM Flex System x240 Compute Node Types 7863, 8737, 8738, and 8956.

  • Particulate contamination
    Attention: 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.
  1. Chassis is powered on.
  2. A3 - Derate maximum allowable temperature 1°C/175 m above 950 m.
  3. 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 (~25C), the dew point (-12 °C) represents the minimum moisture level; above the intersection, relative humidity (8%) is the minimum.
  4. 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:
    1. 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).
    2. During maintenance on any hardware, a properly functioning wrist strap must be used by any personnel who contacts IT equipment.
  5. 5°C/hr for data centers employing tape drives and 20°C/hr for data centers employing disk drives.
  6. Chassis is removed from original shipping container and is installed but not in use, for example, during repair, maintenance, or upgrade.
  7. The equipment acclimation period is 1 hour per 20°C of temperature change from the shipping environment to the operating environment.
  8. Condensation, but not rain, is acceptable.
