Using NTB (Non Transparent Bridge ) to interconnect 2 Xeon based servers

Is it possible to use NTB in Xeon servers to connect in a point-to-point manner? Is there any documentation available for the same. I could see NTB support is available in kernel, but not sure how to make use of it for interconnect two servers.

Hi Bineesh, The NTB allows hosts on each side of the bridge to exchange indormation about the status through scratchpad registers, doorbell registers, and heartbeat messages. Scratchpad Registers: These r/w from both sides of the NTB. Doorbell Registers: used to send interrupt. These are software controlled interrupt request registers with associated masking registers for each interface on the NTB. These registers can be accessed from both sides. Heartbeat Messages: are sent from primary to the secondary host to indicate it is still alive. The secondary host monitors the state of the primary host and takes appropriate action upon detection of the failure. We like to know if you can provide us with information about the configurations you have set on your systems. >Motherboard model and brand name: >Processor Model and How many processors are you going to use: >Memory: >OS: On the other hand, could you please so kind and provide us the architecture and design that you are trying to implement on your system? I will be waiting your outcome in order to proceed with the next step. Regards, Emeth O. Intel Customer Support Technician Under Contract to Intel Corporation
