When the capacity of each RDIMM is less than or equal to 64 GB, standard fans are used.
When the capacity of each RDIMM is equal to or greater than 128 GB, performance fans are used.
When the capacity of each RDIMM is 256 GB, the ambient temperature must be limited to 30°C or lower.

For T400 and T1000, only a maximum of six single-wide GPU adapters are supported.
For the chassis with 16 x 2.5-inch front drives, a maximum of two A40 or H100 GPU adapters are supported in PCIe slot 2 and slot 5 when the ambient temperature is 30°C.
A40 is not supported by the chassis with 24 x 2.5-inch front drives.
