Adding a virtual network

You can add a new virtual network to a cluster configuration to enable a multi-tenant environment connection to a cluster running Element software.

Before you begin

Attention: You must consider the following criteria for this configuration:
  • VLANs that are not VRF-enabled require initiators to be in the same subnet as the SVIP.
  • VLANs that are VRF-enabled do not require initiators to be in the same subnet as the SVIP, and routing is supported.
  • The default SVIP does not require initiators to be in the same subnet as the SVIP, and routing is supported.

About this task

When a virtual network is added, an interface for each node is created and each requires a virtual network IP address. The number of IP addresses you specify when creating a new virtual network must be equal to or greater than the number of nodes in the cluster. Virtual network addresses are bulk provisioned by and assigned to individual nodes automatically. You do not need to manually assign virtual network addresses to the nodes in the cluster.

Steps

  1. Click Cluster > Network.
  2. Click Create VLAN.
  3. In the Create a New VLAN dialog box, enter values in the following fields:
    • VLAN Name
    • VLAN Tag
    • SVIP
    • Netmask
    • (Optional) Description
  4. Enter the Starting IP address for the range of IP addresses in IP Address Blocks.
  5. Enter the Size of the IP range as the number of IP addresses to include in the block.
  6. Click Add a Block to add a non-continuous block of IP addresses for this VLAN.
  7. Click Create VLAN.
