Multitenant networking in Element storage clusters allows traffic between multiple clients that are on separate logical networks to be connected to one Element storage cluster without layer 3 routing.
Connections to the storage cluster are segregated in the networking stack through the use of VLAN tagging.
Prerequisites for setting up a multitenant virtual network
- You must have identified the block of client network IP addresses to be assigned to the virtual networks on the storage nodes.
- You must have identified a client storage network IP (SVIP) address to be used as an endpoint for all storage traffic.
Virtual networking order of operations
- Use the AddVirtualNetwork method to bulk provision the IP addresses you enter.
After you add a virtual network, the cluster automatically performs the following steps:
- Each storage node creates a virtual network interface.
- Each storage node is assigned a VLAN address that can be routed to using the virtual SVIP.
- VLAN IP addresses persist on each node in the event of a node reboot.
- When the virtual network interface and VLAN addresses have been assigned, you can assign client network traffic to the virtual SVIP.
