When using Dual CPU motherboard to work with Netstor GPU expansion chassis, there will be CPU1 and CPU2 on the PC motherboard. Normally some PCIe slots are controlled by CPU1, and some PCIe slots are controlled by CPU2.

For the Dual CPU motherboard design, because all the I/O and motherboard peripheral devices are linked to CPU1 in support of work, more PCIe resources will be occupied and be utilized on CPU1. Therefore, CPU2 will naturally have more PCIe resources to be assigned and be allocated to the GPU cards on system in support of the application.

Example:

Tips:

1. Check PC motherboard’s user manual first, and verify which PCIe slots on PC motherboard are controlled by CPU2. Then install NP970AG3-H host card in the PCIe 3.0 ×16 slot controlled by CPU2 to have the max ×16 bandwidth.
2. Note generally do not install a third-party card in the PCIe slot next to the PCIe 3.0 ×16 slot for NP970AG3-H host card as doing so will result in Netstor host card’s PCIe 3.0 ×16 slot becoming ×8 bandwidth.
