100mm Slim Extensions for RDHX

As an alternative to the 180mm rack extension, the 42U Onyx rack also support an 100mm slim extension at the rear of the cabinet with the Rear Door Heat Exchanger (RDHX) attached. The 100mm Slim Extension is only supported on the rear of the cabinet.

Rear doors

Depending on the choice of cooling and preference of aesthetics the Heavy Duty Rack Cabinet can be ordered with a perforated rear door for ambient air cooling, a passive Rear Door Heat Exchanger leveraging Lenovo Neptune technology for liquid cooling or no rear door at all to, for example, show case a beautiful cabling job.

Ordering information is listed in the following table.

The following figure shows the standard rear door and the Rear Door Heat Exchanger, installed in 42U rack cabinets.

Figure 5. Standard rear door and the Rear Door Heat Exchanger

Side Panels

The Heavy Duty Rack Cabinets can be configured with and without side panels or even just one with the choice of side, to map exactly to your requirements. Choose both side panels if the rack cabinet will be placed standalone or you want to isolate airflow, choose one side panel with left or right placement for racks that are at the end of a rack row and leave them off for racks that are placed inside the row.

Attachment brackets to connect and secure adjacent racks together are included with all racks.

Cable management options

Proper cable management is a crucial part of a rack design to allow for optimal airflow and also easy serviceability of the populated rack cabinet. For that reason, the Heavy Duty Rack Cabinet comes by default equipped with rear cable management anchor points for a clean and beautiful cabling.

Additionally there is a choice for front cable management brackets to provide additional anchor points for front-cabled systems, and cable management brackets for use in the rear when 0U PDUs are installed.

The Heavy Duty Rack Cabinets support both 0U power distribution units (PDUs) mounted vertically in the rear as well as 1U PDUs that can be installed either within the horizontal rack space or the vertical rack side pockets.

The following table lists the power distribution units (PDUs) that are offered by Lenovo.

For more information, see the Lenovo Press documents in the PDU category:
https://lenovopress.com/servers/options/pdu

Lenovo Heavy Duty Rack Cabinets support water infrastructure used to cool the major components of the servers installed. The components of the water-cooled solution are as follows:

• Multi-port water manifold, installed in the rear of the rack cabinet

  Typical use:

  • 45-port manifold: 48U rack cabinet for 45x 1U or 23x 2U servers
  • 38-port manifold: 42U/48U rack cabinet for 38x 1U or 19x 2U servers
  • 24-port manifold: 42U/48U rack cabinet for 24x 1U or 12x 2U servers where one N1380 enclosure is installed at the bottom of the rack
  • 10-port manifold: 42U/48U rack cabinet for 10x 1U or 5x 2U servers where two N1380 enclosures is installed at the bottom of the rack

  The manifold provides quick-disconnect couplings that each server in the rack is connected to. Two 0U mounting points are required for the water manifolds, at the rear of the rack cabinet, one either side. Ordering information is in the table below.

• Coolant distribution unit (CDU), either in-rack or in-row:
  • In-rack CDUs are installed at the bottom of the rack cabinet. The supported in-rack CDU is the Lenovo Neptune DWC RM100 In-Rack CDU as described in the RM100 In-Rack Coolant Distribution Unit section.
  • In-row CDUs are separate cabinets that are typically installed at the end of a row of rack cabinets. Examples of suitable in-row CDUs include (but not limited to):
    • Vertiv Liebert XDU60 60KW CDU
• Hose kit to connect to the CDU to the manifold

  Ordering information is in the table below.

The following figure shows the 38-drop water manifold and in-rack CDU installed in either a 42U or 48U rack cabinet.

Figure 6. 38-drop water manifold and connections for an in-rack CDU

Ordering information for the water manifold and hoses is listed in the following table.

Expected performance of the 42U heat exchanger is illustrated in the following figure for a typical inlet air temperature of 27°C (80.6°F), with a fully populated rack, near uniform power dissipation, and a 30-40 kW heat load.

Figure 8. Typical performance of the 42U heat exchanger, 30 kW heat load

Performance data is shown in the following figure for a 20 kW heat load. Because of the lower heat load, a specific level of cooling can be achieved with warmer water, a lower flow rate, or both.

Figure 9. Typical performance of the 42U heat exchanger, 20 kW heat load

By selecting the correct water inlet temperature and water flow rate, you can achieve the necessary heat removal. A heat removal of 100% indicates that an amount of heat equivalent to that generated by the devices has been removed by the heat exchanger and the average air temperature leaving the heat exchanger is identical to that entering the rack (27°C /80.6°F in this example).

Heat removal in excess of 100% indicates that the heat exchanger not only removed all of the heat generated by the devices but further cooled the air so that the average air temperature leaving the rack is actually lower than that entering the rack.

A given water temperature may be used only if the system that is supplying the water is able to measure the room dew point and automatically adjust the water temperature accordingly. Otherwise, the water temperature must be above the maximum dew point that is allowed at that data center installation.

Customers should work with their Lenovo Sales Architects and Datacenter Infrastructure Specialists for an exact sizing for their project.

The following table lists the dimensions and weight of the rack cabinets.

The following image shows the location of the casters (wheels) in relation to the overall dimensions of the rack cabinet.

Figure 10. Location of the casters (distances in millimeters)

The Heavy Duty Rack Cabinets have the following operating environment requirements:

RDHX water requirements

The water requirements for the Rear Door Heat Exchanger is as follows:

• Water Temperature:
  • Above dewpoint
  • 18°C / 64.4°F for ASHRAE Class 1 Environment
  • 22°C / 71.6°F for ASHRAE Class 2 Environment
• Water volume: 9 liters (2.4 gallons)
• Maximum pressure: 689.66 kPa (20psi) / 6.9 bars
• Minimum water flow rate: 22.7 liters (6 gallons) per minute
• Maximum water flow rate: 56.8 liters (15 gallons) per minute
• Water connections: 3/4 quick connect

Note: 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 treated with anti-biological and anti-corrosion measures. The water cannot originate from the primary chilled-water system for the building but must be supplied as part of a secondary, closed-loop system.

Important: Do not use glycol solutions, because they can adversely affect the cooling performance of the heat exchanger

Tilt, shock and vibration

The rack cabinets have the following tilt, vibration and shock limits:

• Tilt:
  • 42U cabinet: 12.5 degrees
  • 48U cabinet: 10 degrees
• Vibration: 0.8 G rms at 2 Hz to 200 Hz for 15 minutes
