Configuration
3.5 inch x4 hard drives
(PCIe x2/x3)
2.5 inch x8 hard drives
(PCIe x3/x2)
NOTE:
When installing DCPMMs for systems that support 200W or higher wattage processors, the ambient
o
temperature of 30
C must be adhered to ensure proper cooling and to avoid excess processor throttling, which may
impact system performance.

Ambient temperature limitations
The following table lists configurations that require ambient temperature less than 35°C.
NOTE:
The ambient temperature limit must be adhered to ensure proper cooling and to avoid excess processor
throttling, which may impact system performance.
