Storage controller option population guidelines

To maintain optimal thermal conditions when installing a P-series Smart Array Controller or a Smart HBA option, Hewlett Packard Enterprise recommends the following population guidelines:

Expansion slot H240 H241 P440 P441 P841
Slot 1 PCIe3 x8 (8, 4, 1) low-profile, standup Yes Yes Yes Yes
Slot 2 PCIe3 x16 (16, 8, 4, 1) low-profile, standup Yes Yes Yes Yes
Riser slot 3 PCIe3 x8 (8, 4, 1) full-height, half-length Yes Yes Yes Yes Yes
Riser slot 4 PCIe3 x8 (8, 4, 1) full-height, half-length Yes Yes Yes Yes Yes
Slot 5 PCIe3 x16 (16, 8, 4, 1) low-profile, standup Yes* Yes Yes* Yes
Slot 6 PCIe3 x8 (8, 4, 1) low-profile, standup Yes* Yes Yes* Yes
Slot 7 PCIe3 x16 (16, 8, 4, 1) low-profile, standup Yes* Yes Yes* Yes
* When an H240 HBA or a P440 Smart Array Controller is installed in PCIe3 expansion slot 5, 6 or 7, a rear drive cage must be installed.
