Generally, Cluster Nodes that are to be equipped with PCI Express interconnect adapters should be placed close to each other to keep cable lengths short. This reduces costs and allows for better routing of the cables.
Dolphin PCI Express PX supports both copper and fiber optic cables. The maximum cable length for PXH810 is 5 meter for copper cables and 100 meter for fiber. The PXH830 card support up to 9 meter copper cables. Please ask your Dolphin sales representative for details.
Once you have decided on the physical Cluster Node placement, the cables should be ordered in the according lengths. The Dolphin sales representative will assist you in selecting the right cable lengths.
