Determining rack locations
The height of the node and the storage shelves require a different rack unit (RU) space. The node needs 2RU rack space and each storage shelf needs 4RU.
To help you identify RU spacing, many rack manufacturers typically use a system of lines and sequential numbers starting at the bottom of the rack. The front and the rear of the rack are marked the same to ensure that the rails are installed straight and level.
One RU has three holes. The holes for one RU are typically marked with a line below the bottom hole and another line above the top hole. A number at the center hole identifies where the RU appears in the rack.
Figure: Rack RU space markings shows the markings as described.
Use the node and the storage shelf Rack Templates to determine the mounting locations.
Best practices for hardware installation are as follows:
When you install the rails, be sure to use complete RUs. Do not use holes from different RUs.
The storage shelves are much heavier than the node and should be installed as close to the bottom of the rack as possible.
The node should always be installed on top of the storage shelves.
Do not leave any spaces between the compute node and a storage shelf, or between two storage shelves.
When you add expansion shelves to an operational appliance system, turn off the node(s), the primary shelf, and existing expansion shelves.
To determine rack locations for the hardware
- Determine the total number of rack units (RUs) that you need as follows:
A compute node (2RU) and a Primary Storage Shelf (4RU) require a total of six RUs.
A compute node (2RU), a Primary Storage Shelf (4RU), and one Expansion Storage Shelf (4RU) require a total of ten RUs.
A compute node (2RU), a Primary Storage Shelf (4RU), and five Expansion Storage Shelves (4RU each) require a total of 26 RUs.
An HA configuration with a compute node (2RU), a partner node (2U), a Primary Shelf (4RU), and one Expansion Shelf (4RU) requires 12 RUs.
An HA configuration with a compute node (2RU), a partner node (2U), a Primary Shelf (4RU), and five Expansion Shelves (4RU each) requires 28 RUs.
- Use the Rack Templates that are provided with the hardware to determine RU locations.
- Record the rack positions to help you locate them easily when mounting the hardware.
