Virtual Floating IPs (VIP)

FlexSDS provides Virtual Floating IP (VIP) functionality that allows users to configure a set of IP addresses within a storage cluster. Each VIP is dynamically bound to an active node. If the bound node fails, the VIP is automatically taken over by another healthy node, ensuring continuous service availability.
The VIP feature is typically used for:

• NFS services
• Distributed Parallel File System (DPFS)
• FlexSDS management platform high availability

Managing VIPs via CLI
Users can manage Virtual Floating IPs using the following commands.

Add a VIP

flexsds vip add -i 192.168.20.11 -d ib0or
flexsds vip add --ip 192.168.20.11 --device ib0
Parameters:
• -i, --ip : Virtual IP address
• -d, --device : Network interface to bind (e.g., ib0, eth0)

Remove a VIP

flexsds vip remove -i 192.168.20.11 -d ib0or
flexsds vip remove --ip 192.168.20.11 --device ib0

List VIPs in the Cluster

flexsds vip list
This command displays all configured Virtual Floating IPs in the storage cluster, along with their current node bindings and status.
