Host Groups and Supported Protocols in PowerStore

Host Groups: Host groups in PowerStore allow you to group multiple hosts together for easier management and access control. When you create a host group, you specify the protocol that the hosts in that group will use to connect to the PowerStore appliance.

Supported Protocols: PowerStore supports several protocols for host connectivity, but when creating a host group, you can choose from these two:

iSCSI: A widely used IP-based storage networking protocol.

FC (Fibre Channel): A high-speed network technology primarily used for storage networking.

Why other options are incorrect:

A . InfiniBand: While PowerStore supports InfiniBand for NVMe over Fabrics (NVMe-oF), it's not a selectable option when creating a host group.

C . NVMe/TCP: Similar to InfiniBand, NVMe/TCP is supported for NVMe-oF, but it's not a protocol choice during host group creation.

Key Considerations for Host Groups

Single Protocol per Host Group: A host group can only use one protocol. All hosts within the group must use the same protocol (either iSCSI or FC) to connect to PowerStore.

Host Mapping: After creating a host group, you can map volumes to the group, granting access to all hosts within that group.
