Dimensions and determining rack locations
Physical specifications for the compute node include the following.
Each node is two rack units (2RU) high.
Node measurements are listed below.
Height: 21.97cm (8.65")
Width: 48.26cm (19")
Length/depth: 79.38cm (31.25")
The compute node rails are extensible to 813mm (32in). This distance is the maximum depth that is allowed between rack posts.
Physical specifications for the 5U84 storage shelves include the following.
Each storage shelf is 5RU high.
Storage shelf measurements are listed below.
Height: 22.23cm (8.75") (approximately 5U - shelf, overall)
Width: 48.26cm (19") (across the mounting flange)
Length/depth: 93.35cm (36.75") from the rear of the front flanges to the extreme rear of the storage shelf chassis.
Note:
The 5U84 storage shelf is longer than a standard IEC-compliant rack. Be sure that your rack cabinet and Power Distribution Units accommodate the length of the storage shelves.
The storage shelf rails measure 71.3cm to 88.4cm (28" to 34.8") in length. Be sure that your rack accommodates this distance from the inside of the front post to the inside of the rear post. Plan for additional space to accommodate power strips, power cords, and other cables.
When you plan the installation be sure to allocate enough space for all of the hardware.
A typical installation has the storage shelves on the bottom and the compute node(s) at the top.
To help you identify RU spacing, many rack manufacturers 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 at the top hole.
Use the rack templates to determine the mounting locations for all devices.
To determine rack locations for the hardware
- Determine the total number of rack units (RUs) that you need as follows:
Two compute nodes (2RU each) and one storage shelf (5RU) require 9RUs of height in the rack.
Two compute nodes (2RU each) and four storage shelves (5RUs) require 24RUs of height in the rack.
- Use the rack templates to determine RU locations.
- Fold the compute node templates at the horizontal yellow lines.
- Use the following graphics to determine where pins and screws for the storage shelves fit into the rack.
The front of each rail includes four pins that insert into the rear of the front rack post. One screw fits into the middle hole of the middle RU.
The rear of each rail includes four pins that insert into the inside of the rear rack post. Two screws insert into the front of the rear rack post. The screws install into the middle hole in the first and the fifth RU.
- Record the rack positions to help you locate them easily when mounting the hardware.
