A summary of the features and specifications of the enclosure.
One DW612 Enclosure could contain six SD650 V2/SD650-N V2 trays.
Table 1. Enclosure specifications
Height: 263.3 mm (10.37 inches)
Depth: 930.6 mm (36.64 inches)
Width: 447 mm (17.6 inches)
Empty enclosure (with midplane and cables): approximately 23.6 kg (52.04 lbs)
Fully configured (stand-alone):
Enclosure with six SD650 V2 trays: approximately 156.54 kg (345.17 lbs)
Enclosure with six SD650-N V2 trays: approximately 168.94 kg (372.51 lbs)
SD650 V2 tray:
Supports six hot-swap ac power supplies (conditionally upgradable to nine with ThinkSystem 2400W (230V) v4 Platinum hot-swap power supply, see PSU configuration).
Input voltage: 200-240 Vac
SD650-N V2 tray:
Supports six hot-swap ac power supplies (conditionally upgradable to nine power supplies, see PSU configuration).
Input voltage: 200-240 Vac
SD650-N V2 tray supports ThinkSystem 2400W (230V) v4 Platinum hot-swap power supply Delta only. All the installed power supply units must be ThinkSystem 2400W (230V) v4 Platinum hot-swap power supply Delta.
Power supplies and redundant power supplies in the enclosure must be with the same brand, power rating, wattage or efficiency level.
SD650 V2 tray: 6.0 liters per minute per enclosure, assuming 1.0 lpm per compute tray with 6 trays per enclosure (1 tray consists of 2 compute nodes)
For processors below 205W: 6.0 liters per minute per enclosure, assuming 1.0 lpm per compute tray with 6 trays per enclosure
For processors above 205W: 7.5 liters per minute per enclosure, assuming 1.25 lpm per compute tray with 6 trays per enclosure
SD650-N V2 tray with 40/80 GB NVIDIA HGX™ A100 4-GPU: 21.0 liters per minute per enclosure, assuming 3.5 lpm per compute tray with 6 trays per enclosure (1 tray consists of 1 compute node and 1 GPU node)
The water required to initially fill the system side cooling loop must be reasonably clean, bacteria- free water (<100 CFU/ml) such as de-mineralized water, reverse osmosis water, de-ionized water, or distilled water. The water must be filtered with an in-line 50 micron filter (approximately 288 mesh). The water must be treated with anti-biological and anti-corrosion measures.
The SD650 V2 tray, the SD650-N V2 tray and DW612 Enclosure are supported in the following environment:
Air temperature requirements:
Operating: ASHRAE class A2: 10°C - 35°C (50°F - 95°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F) with every 300 m (984 ft) of altitude increase.
Powered off: 5°C - 45°C (41°F - 113°F)
Shipping/storage: -40°C - 60°C (-40°F - 140°F)
To use the 240 GB M.2 drive, the following conditions must be met:
If inlet water temperature is 45°C, then the ambient air temperature cannot exceed 27°C.
If inlet water temperature is 30°C, then the ambient air temperature cannot exceed 35°C.
Relative humidity (non-condensing):
Operating: ASHRAE Class A2: 8% - 80%, maximum dew point : 21°C (70°F)
Shipment/storage: 8% - 90%
Maximum altitude: 3048 m (10 000 ft)
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 solution. For information about the limits for particulates and gases, see Particulate contamination.
The solution is designed for standard data center environment and recommended to be placed in industrial data center.
