NTB Mode
The MXH930 card can be combined with the MXS924 24 port PCIe switch to create larger PCIe networks. Each node typically has a
MXH930 adapter and a x4, x8 or x16 cable connection to the MXS924 switch. All MXH930 adapter cards operate in NTB mode.
Please consult the MXS924 Users Guide for more details. Dip switches should be set as specified in Table 3: DIP Switch settings on
page 9. Some configuration examples can be found below, please contact Dolphin for more information how to build larger systems
up to 60 nodes.
6 Node, x16 Link Width
In this use case, each MXH930 card is connected to the switch using four x4 cables to create a x16 Gen4 link. The aggregated link
speed is 256 GT/s.

12 Node, x8 Link Width
In this use case, each MXH930 card is connected to the switch using two cables to create a x8 Gen4 link. The aggregated link speed
is 128 GT/s.

24 Node, x4 Link Width
In this use case, each MXH930 card is connected to the switch using one x4 cables to create a x4 Gen4 link. The aggregated link
speed is 64 GT/s.
