NVMe SMBus Headers
NVMe SMBus (I
2
C) headers (JNVI
2
C1/2), used for PCI-E SMBus clock and data connections,
provide hot-plug support via a dedicated SMBus interface. This feature is only available for a
Supermicro complete system with an SMCI-proprietary NVMe add-on card and cable installed.
See the table below for pin definitions.

NVMe Connectors
Four NVMe connectors (NVME10/NVME11 & NVME12/NVME13) are used for high-speed
PCI-E storage devices. NVME10/NVME11 are supported by CPU1, and NVME12/NVME13
are for CPU2.
