Dell PowerFlex 4.5.x Administration Guide

Defining a network

Adding the details of an existing network enables PowerFlex Manager to automatically configure nodes that are connected to the network.

1. On the menu bar, click Settings and then click Networking.
2. Click Networks.
   The Networks page opens.
3. Click Define. The Define Network page opens.
4. In the Name field, enter the name of the network. Optionally, in the Description field, enter a description for the network.
5. From the Network Type drop-down list, select one of the following network types:
   • General Purpose LAN
   • Hypervisor Management
   • Hypervisor Migration
   • Hardware Management
   • PowerFlex Data
   • PowerFlex Data (Client Traffic Only)
   • PowerFlex Data (Server Traffic Only)
   • PowerFlex Replication
   • NAS File Management
   • NAS File Data
   • PowerFlex Management

   For a PowerFlex configuration that uses a hyperconverged architecture with two data networks, you typically have two networks that are defined with the PowerFlex data network type. The PowerFlex data network type supports both client and server communications. The PowerFlex data network type is used with hyperconverged resource groups.

   For a PowerFlex configuration that uses a two-layer architecture with four dedicated data networks, you typically have two PowerFlex (client traffic only) VLANs and two PowerFlex data (server traffic only) VLANs. These network types are used with storage-only and compute-only resource groups.

6. In the VLAN ID field, enter a VLAN ID between 1 and 4094.
   NOTE:PowerFlex Manager uses the VLAN ID to configure I/O modules that enable network traffic to flow from the node to configured networks during deployment.
7. Optionally, select the Configure Static IP Address Ranges check box, and then do the following:
   NOTE:The Configure Static IP Address Ranges check box is not available for all network types. For example, you cannot configure a static IP address range for the operating system installation network type. You cannot select or clear this check box to configure static IP address pools after a network is created.
   1. In the Subnet box, enter the IP address for the subnet. The subnet is used to support static routes for data and replication networks.
   2. In the Subnet Mask box, enter the subnet mask.
   3. In the Gateway box, enter the default gateway IP address for routing network traffic.
   4. Optionally, in the Primary DNS and Secondary DNS fields, enter the IP addresses of primary DNS and secondary DNS.
   5. Optionally, in the DNS Suffix field, enter the DNS suffix to append for hostname resolution.
   6. To add an IP address range, click Add IP Address Range. In the row, indicate the role in PowerFlex nodes for the IP address range and then specify a starting and ending IP address for the range. For the Role, select either:
      • Server or Client: Range is assigned to the server and client roles.
      • Client Only: Range is assigned to the client role on PowerFlex hyperconverged nodes and PowerFlex compute-only nodes.
      • Server Only: Range is assigned to the server role on PowerFlex hyperconverged nodes and PowerFlex storage-only nodes.

      Repeat this step to add IP address ranges based on the requirement. For example, you can use one range for SDC and another for SDS.

      NOTE:IP address ranges cannot overlap. For example, you cannot create an IP address range of 10.10.10.1–10.10.10.100 and another range of 10.10.10.50–10.10.10.150.
8. Click Save.
