9 DELL EMC HPC Solution for Life Sciences v1.1: Deployment Best Practices | Document ID | version (optional)
3.3 Network configuration
This solution comprises of two network switches, Dell Networking S3048-ON and Dell Networking H1048-
OPF switch, for management network and high-speed interconnects respectively.
The port assignment of the Dell Networking S3048-ON switch for the Intel® OPA or IB versions of the solution
is as follows.
• Ports 01-04 and 27–52 are assigned to the cluster’s private management network to be used by Bright
Cluster Manager® connecting master, login, CIFS gateway and compute nodes. The PowerEdge C6320
server’s ethernet and iDRAC constitute a majority of these ports.
• Ports 06–09 are used for the private network associated with NSS7.0-HA.
• The rest of the port 05 and ports 12–26 are allocated to the Lustre solution for its private management
network
• Port 10 and 11 are used for the PDUs.
Note: It is required to install four SFP+ to RJ45 transceivers in Dell Networking S3048-ON switch ports 49-52.
High-speed interconnect among master, login and compute nodes is configured through the Dell Networking
H1048-OPF with 1:1 non-blocking topology. One port is assigned to each master, login and CIFS gateway
and compute nodes. NSS7.0-HA needs two ports while DELL EMC HPC Lustre Storage requires five ports.
