Specifications
The expansion blade has the following specifications:
30 mm expansion blade, attaches to a supported server blade through the PCIe x16 CFFh connector
Standard NVIDIA GPU computing module
Up to four expansion blades can be attached to the base server. With four expansion blades attached,
the total width of the server is 150 mm.
The CFFh slot remains usable on the top-most expansion blade, for use in BladeCenter H and HT
configurations. Supported CFFh cards are listed in Table 4.
