This section explains how to wire the out-of-band management (IPMI) port, 25 Gbps or 100 Gbps ports, and power on Supermicro 1014S nodes.
This platform uses a unified networking configuration in which the same NIC handles back-end and front-end traffic. In this configuration, each networking port provides communication with clients and between nodes. You can connect the NIC’s ports to the same switch or to different switches.
The two rightmost Ethernet ports on the back of your node are unused.
Step 1: Connecting the Out-of-Band Management (IPMI) Port
The dedicated out-of-band management port allows functionality such as remote display, control, and power. The port uses the Intelligent Platform Management Interface (IPMI) protocol. Connect the IPMI port first on the back of your node (above the USB ports).
The IPMI username and password are unrelated to your Qumulo administrative credentials.
To configure the IPMI port, you must use the IPMI Management Utility installed on the motherboard. For more information, see Supermicro BMC User Guide X12.
Step 2: Connecting the 25 Gbps or 100 Gbps Ports
After you connect the IPMI port, connect your 25 Gbps or 100 Gbps ports (compatible with QSFP28 and QSFP56). There are two 25 Gbps or 100 Gbps ports on the back of your node. This platform uses a unified networking configuration in which the same NIC handles back-end and front-end traffic. In this configuration, each networking port provides communication with clients and between nodes. You can connect the NIC’s ports to the same switch or to different switches.
To identify the
eth port, run the following command:for i in /sys/class/net/eth*; \
do echo $i; \
cat $i/device/uevent | \
grep -i pci_slot; \
doneStep 3: Connecting the Power
After you connect your 25 Gbps or 100 Gbps ports, connect power to the node. There are two power sockets on the back of your node. To maximize redundancy, connect each PSU to a separate power supply or power distribution unit (PDU).
