Public IP Addresses

By default, access to VPSA instances from the public Internet is not available, for security and privacy reasons.

The VPSA Front-End IP address is used for VPSA management via the UI and REST API. It is also used for data IO workload, where host connectivity is via iSCSI, NFS, and SMB protocols. The VPSA Front-End IP address is allocated on the Zadara Storage Cloud Front-End network. Only servers in the Cloud Servers network can reach this IP address. Servers outside this network cannot access it.

To enable access to VPSA instances from outside the cloud network, Public IP addresses are allocated in the Cloud management interface, and can be assigned to VPSA instances.

A typical use case requiring Public IP addresses is VPSA Asynchronous Remote Mirroring. This involves two VPSAs in different regions, or between on-premise and public cloud deployments, or even between different Cloud Providers for Disaster Recovery (DR). In these cases, communication between the VPSAs takes place via an authenticated and encrypted channel over the public Internet , thus requiring Public IPs.

Cloud admins can use Command Center to view, define, edit and delete public IP addresses, and to assign them to VPSA instances.
