IP Address Planning

IP Address Planning

Overview

Table 4-2 lists the IP addresses to be planned for OceanStor 9000.

To avoid readjusting network segments in the future capacity expansion, reserve IP addresses for nodes and switches to be added.

You are advised to reserve more than two IP addresses on each network segment for commissioning.

Table 4-2  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.

The following IP addresses also need to be assigned:
  • 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

  • Actual number of IP addresses: number of nodes x 2
  • Number of temporary IP addresses for software installation: number of nodes
  • Each storage node is assigned two back-end storage network IP addresses. By default, the planning tool assigns IP addresses that reside on the network segment 172.16.0.0 to 172.16.255.255 to the back-end storage network. The default subnet mask is 255.255.0.0 (the mask length is at least 16).
  • During the software installation, you need to apply for temporary IP addresses for OceanStor 9000.

    Assign n (n = Number of nodes) IP addresses for the back-end storage network. During the software installation, assign one temporary IP address for each node using Dynamic Host Configuration Protocol (DHCP). Those IP addresses are temporarily assigned to each node during the software installation and will be automatically deleted after the software is installed. Those temporary IP addresses cannot overlap the planned back-end network IP addresses.

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 + 2
  • 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.
  • Assign one floating management IP address for OceanStor 9000.
  • Assign one management IP address for the switch on the back-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 information about the user's network must be obtained:

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

Networking Example

An enterprise uses the file system service. The network is shown as Figure 4-7.

Figure 4-7  Networking example

Table 4-3, Table 4-4, and Table 4-5 show the IP address planning when three M nodes are deployed.
Table 4-3  Management network IP address planning

Management IP Address

In total seven management IP addresses are required for interconnection with the management network, of which five are official and two are temporary.
