Features and specifications

The following table is a summary of the features and specifications of the NeXtScale nx360 M4 compute node.

Microprocessor (depending on the model):

• Supports up to two multi-core microprocessors (one installed)
• Level-3 cache
• Two QuickPath Interconnect (QPI) links speed up to 8.0 GT per second

Note

• Use the Setup utility to determine the type and speed of the microprocessors in the server.
• For a list of supported microprocessors, see Lenovo ServerProven compatability.

Memory:

• 8 dual inline memory module (DIMM) connectors
• Type: Low-profile (LP) double-data rate (DDR3) DRAM
• Supports 4 GB, 8 GB, and 16 GB DIMMs with up to 128 GB of total memory on the system board
• Support for UDIMMs and RDIMMs (combining is not supported)

Integrated functions:

• Integrated Management Module II (IMM2), which consolidates multiple management functions in a single chip.
• Concurrent COM/VGA/2x USB (KVM)
• System error LEDs
• Software RAID supportability for RAID level-0, RAID level-1, or RAID level-10
• Hardware RAID supportability for RAID level-0, RAID level-1, RAID level-5, or RAID level-10
• Wake on LAN (WOL)

Drive expansion bays (depending on the model):

Supports up to eight 3.5-inch SATA (if the storage tray is installed, up to 7 in the storage tray and 1 in the compute node), two 2.5-inch SATA/SAS, or four 1.8-inch solid-state drives.¹

Attention

As a general consideration, do not mix standard 512-byte and advanced 4-KB format drives in the same RAID array because it might lead to potential performance issues.

Upgradeable firmware:

All firmware is field upgradeable.

• Compute node
  • PCI Express x16 (x8 mechanically) slots (PCIe3.0, full-height, half-length)

• GPU tray
  • Two PCI Express x16 (x16 mechanically) slots (PCIe3.0, full-height, full-length)

• Compute node
  • Height: 41 mm (1.6 in)
  • Depth: 659 mm (25.9 in)
  • Width: 216 mm (8.5 in)
  • Weight estimation (based on the LFF HDD within computer node): 6.05 kg (13.31 lb)
• Storage tray
  • Height: 58.3 mm (2.3 in)
  • Depth: 659 mm (25.9 in)
  • Width: 216 mm (8.5 in)
  • Weight estimation (with 7 hard disk drives installed): 8.64 kg (19 lb)
• GPU tray
  • Height: 58.3 mm (2.3 in)
  • Depth: 659 mm (25.9 in)
  • Width: 216 mm (8.5 in)
  • Weight estimation (with no GPU adapter installed): 3.33 kg (7.34 lb)

Environment:

The NeXtScale nx360 M4 compute node complies with ASHRAE class A3 specifications.

Server on²

• Temperature: 5°C to 40°C (41°F to 104°F)³
• Humidity, non-condensing: -12°C dew point (10.4°F) and 8% to 85% relative humidity^4,5
• Maximum dew point: 24°C (75°F)
• Maximum altitude: 3048 m (10,000 ft)
• Maximum rate of temperature change: 5°C/hr (41°F/hr)⁶

Environment:

Server off⁷:

• Temperature: 5°C to 45°C (41°F to 113°F)
• Relative humidity: 8% to 85%
• Maximum dew point: 27°C (80.6°F)

Storage (non-operating):

• Temperature: 1°C to 60°C (33.8°F to 140.0°F)
• Maximum altitude: 3,050 m (10,000 ft)
• Relative humidity: 5% to 80%

Particulate contamination

Attention

• Design to ASHRAE Class A3, temperature: 36°C - 40°C (96.8°F - 104°F), with relaxed support:
  • Support cloud such as workload with no performance degradation acceptable (turbo-off)
  • Under no circumstance, can any combination of the worst case workload and configuration result in system shutdown or design exposure at 40°C
  • The worst case workload (such as linpack and turbo-on) may have performance degradation
• 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.
