What should be a consideration when having casters (rollers/wheels) or feet under the rack?

Show Suggested Answer Hide Answer
Suggested Answer: A

The casters and feet under the rack are used to support the weight of the rack and its equipment, and to allow the rack to be moved if needed. However, the casters and feet should also be designed to avoid putting too much pressure on the floor tile, especially if the data centre uses a raised floor system. A too heavy point load on the floor tile can cause the tile to crack, deform, or collapse, which can damage the rack, the equipment, and the underlying infrastructure. To prevent this, the casters and feet should be larger, so that they can distribute the weight over a larger area and reduce the point load. The casters and feet should also be compatible with the floor type and the load rating of the floor tile.

I think having casters and feet that are not locked is important for flexibility in moving the racks.

I'm going with B. Skirts at the bottom will help with air flow management between the aisles. Gotta keep that hot and cold air separated, you know?

D sounds like a reasonable option too. If the racks need to be moved around, it's important to have unlocked casters or feet to make that easier.

I think the answer is C. Soft material like rubber casters and feet will prevent damage to the raised floor tiles. That's a good consideration to have when setting up racks.

I agree with Kattie, having larger casters and feet can distribute the weight better.
