Host portsets
A host portset defines the set of node ports that a host can use to communicate with the system. Portsets apply to both Ethernet and Fibre Channel (FC) environments. Use portsets to control host access, support isolation between workloads, and provide predictable connectivity.
A host object can be assigned to only one portset. A portset can include multiple hosts. Hosts in a cluster can use different portsets. If you do not assign a portset, the host uses the default portset. NVMe‑FC hosts cannot use the default portset. They must use a user-defined Fibre Channel portset.
For more information and requirements about portsets, see Portsets.
Fibre Channel host portsets
Fibre Channel portsets define the FC target ports that a host can access. You can use these portsets with automated switch zoning tools to create consistent zoning rules.
For more information about Fibre Channel portset, see Configuring Fibre Channel portsets.
Ethernet host portsets
- A host portset can include up to four IP addresses per node.
- A host portset must include at least one IP address before you add a host.
- Host attach IP addresses within a single portset can be on different VLANs or subnets
- Each physical port supports one unique routable IP address with a gateway. The same routable IP can be referenced in multiple portsets.
