IP Address Planning

IP Address Planning

Overview

Table 4-12 lists the IP addresses required for the OceanStor 9000 deployment.

If capacity expansion is required, reserve IP addresses for expansion nodes and switches to prevent network segment adjustment.

You are advised to reserve more than two IP addresses for device commissioning.

Table 4-12  IP address planning

Network Segment Type

Number of IP Addresses

Description

Front-end service network

Number of nodes x 4 + 1

An InfoEqualizer DNS IP address.

If a 10GE network adapter is configured for the front-end service network, assign the following addresses:
  • Assign two IP addresses to each node as their front-end static IP addresses.
  • Assign n (n = Number of nodes x 2) dynamic front-end IP addresses to the IP address pool with the InfoEqualizer function.
NOTE:

Front-end service network IP addresses can be changed in DeviceManager after system deployment.

Back-end storage network

  • Number of IP addresses = Number of nodes x 2
  • Temporary IP addresses for software installation = Number of nodes
  • Assign two back-end storage network IP addresses to each storage node. By default, the planning tool uses 172.16.0.10 to 172.16.255.254 as the back-end storage network IP address range and 255.255.0.0 as the subnet mask (the mask length is at least 16). Keep the default settings as long as no IP address conflict will occur.
  • You also need to apply for the following IP addresses during software installation in OceanStor 9000.

    Assign n (n = number of nodes) back-end storage network IP addresses. Temporary IP addresses used for software installation are assigned by DHCP. In addition, assign one IP address to each storage node. These IP addresses are temporarily assigned to each node during software installation and will be deleted after the installation is complete. Ensure that these temporary back-end storage network IP addresses do not overlap with the planned back-end storage network IP addresses of nodes.

NOTE:

The back-end storage network IP addresses cannot be changed in DeviceManager. Therefore, confirm that you have filled in the correct IP addresses on the deployment page during the deployment.

Management network

  • Number of nodes + Number of switches on the management network + 3
  • Number of temporary IP addresses for software installation: 2
  • Assign one IP address for each node IPMI.
  • Assign one IP address to each switch on the management network switch.
  • Assign one floating management IP address (floating on ports NIC0 of nodes 01 to 03 in the base cabinet) for the OceanStor 9000.
  • Assign one management IP address for the switch on the back-end storage network.
  • Assign one management IP address for the switch on the front-end storage network.
  • Two temporary IP addresses must be obtained during the OceanStor 9000 software installation, which is used to upload file packages during the software installation. The two temporary IP addresses need to be configured on the NIC0 port of the deployment node and the deployment terminal. You can delete them after finishing the software installation.
NOTE:

Two back-end storage network switches are stacked into one switch. You only need to assign one floating IP address to the management network ports on the two switches.

The management network IP address cannot be changed in DeviceManager. Therefore, confirm that you have filled in the correct IP addresses on the deployment page during the deployment.

The following user network information is required:

  • Front-end service network gateway and mask
  • Management network gateway and mask

The following paragraph uses a networking instance to describe how to plan IP addresses. In this instance, temporary IP addresses for software installation are not included.

Networking Example

An enterprise uses the file system service. The network is shown in Figure 4-21. Both the front-end and back-end networks adopt 10GE. In this example, two subnets are created. If subnets are not required, disregard information related to front-end service network 2.

InfoEqualizer DNS IP address

192.168.100.100

If you want to deploy the InfoEqualizer feature, configure a dynamic front-end IP address and an InfoEqualizer DNS IP address for OceanStor 9000. The dynamic front-end IP address needs to be configured in DeviceManager after the OceanStor 9000 software is installed.

Management IP address

10.110.100.200

Administrators can use this IP address to log in to DeviceManager. The IP address can float to ports NIC0 of the first three nodes in the OceanStor 9000 cluster.

Assign one management network IP address to the two CE6800 switches and one to the CE5800 management switch, as shown in Table 4-15.
