Planning of IP addresses on the OceanStor 9000 InfiniBand network

OceanStor 9000 V100R001C01 supports the following typical networking plans: 1. 10GE front-end and 10GE back-end 2. 10GE front-end and GE back-end 3. InfiniBand front-end and InfiniBand back-end 4. 10GE front-end and InfiniBand back-end In the preceding four networking scenarios, the networking tool automatically generates a network plan, hardware connection diagram, and connection table.

OceanStor 9000 InfiniBand (IB) is a common storage networking mode. In IB networking mode, switches and cables are referred to as IB switches and IB cables. IB features high bandwidth (40 Gbit/s) and high speed and applies to high-performance computing (HPC) for astronomical surveys and gene sequencing. It is recommended that OceanStor 9000 IB cables for QSPF+ ports be 3 m-long common copper cables or 10 m-long IB integrated optical cables. Copper cables are recommended only for intra-cabinet installation. Optical cables must be used for cross-cabinet installation.

Management ports in OceanStor 9000 V100R001C01 include NIC0 and IPMI ports. NIC0 ports are used for logging in to system management software, as well as configuring, maintaining, and monitoring the system. IPMI ports on each node are used for hardware system management, including viewing hardware component status and remotely powering on or off nodes. The entire system uses only NIC0 ports on the first three nodes, and one floating management IP address (floating on the NIC0 ports on the three nodes) is planned. An IP address is separately planned for the IPMI port on each node.
