Notes:
1. A storage system contains a base frame (model 988, 986, 985, 984) and any expansion frames (model 88E, 86E,
85E, 84E) that are associated with it.
2. The base frame and expansion frame are bolted together. The weights represent a combined configuration, fully
populated with all enclosures and adapters.
3. Weight distribution areas cannot overlap.
4. Weight distribution areas are calculated for maximum weight of the frames.
Note: Keep any future upgrades in mind, and plan for the highest possible weight distribution.
5. The base and expansion frames in each storage system are bolted to each other. Move one side cover and
mounting brackets from the base frame to the side of the expansion frame. Side clearance for frames that are
bolted together applies to both sides of the assembled frames.
6. The all-flash machine type 533x storage system does not support the configuration noted.
Calculating space requirements
When you are planning the installation site, you must first calculate the total
amount of space that is required for the storage system. Consider future expansion,
and plan accordingly.
Procedure
Complete the following steps to calculate the amount of space that is required for
your storage system.
1. Determine the dimensions of each frame configuration in your storage system.
2. Calculate the total area that is needed for frame configuration by adding the
3. Determine the total space that is needed for the storage system by planning the
4. Verify that the planned space and layout meet the service clearance
Dimensions and weight of individual models
When you are planning the floor and space requirements for your storage system,
consider the dimensions and weights of the frames that compose your storage
system.
The following table provides dimensions and weights.
