Node bays (on front): The
chassis has fourteen node bays that support any of the following configurations:
- Fourteen 1-bay compute nodes
- Seven 2-bay compute nodes (with
the shelves removed from the chassis)
The chassis can also support a combination of 1-bay and 2-bay compute nodes. Note:
- A 1-bay compute node occupies
one node bay in the chassis.
- A 2-bay compute node occupies
two adjacent node bays (horizontally) in the chassis and requires
the chassis shelf to be removed prior to installation.

- Water to air ratio must never exceed 0.026 kg H20/ kg dry air.
- Derate maximum allowable temperature 1°C/213 m above 1829 m. Also
note that this maximum temperature is for a self-standing system,
not located in a rack. If in a rack, deduct 5°C.
- 30°C/hr for data centers employing disk drives, tape drives are
not used.
- The equipment acclimation period is 1 hour per 30°C of temperature
change from the shipping/storage environment to the operating environment.
- One excursion is defined at no more than four days (96 hrs), all
excursions per year should not exceed 15 days (360 hrs).
- The fully configured chassis weight is based on all nodes and
I/O modules being at their maximum design limit.
