Before you begin 9
If IPv6 is not enabled, the HC380 nodes will not be discovered during the installation progress and the
installation and deployment will not complete.
IP address assignments
Note the following points about the IP address assignments:
•
The appliance uses a private IPv4 network (192.168.42.0/24) for internal system communications
that can not be used by other devices sharing the same network.
•
If you plan to expand the number of nodes in the future, Hewlett Packard Enterprise recommends
that you preallocate and leave enough room in the IP address ranges. Preallocating allows you to
add future nodes with IP addresses matching the initial installation subnet ranges. If you choose not
to preallocate the IP addresses now, the future nodes require IP addresses within the subnet ranges
used during initial system deployment.
•
You need between 5 and 119 IPv4 addresses, depending upon whether you are performing an initial
configuration or expanding the HC380 cluster.
o
If you are performing an initial configuration, the system requires between 15 and 119 IPv4
addresses, depending on the number of nodes in your initial configuration and whether you are
installing CloudSystem.
o
If you are expanding an existing HC380 cluster, you need between 5 and 70 IPv4 addresses,
depending on the number of nodes you are adding and whether you are using CloudSystem.
•
Since the OneView InstantOn configuration utility accepts a starting IP address and automatically
increments the IP addresses by the number of nodes in the initial configuration or expansion, some
of the IP addresses must be contiguous.

Planning your appliance networks
Use the topics in this section to plan your appliance networks and determine the IP addresses that are
required for your installation.
ESXi management network IP addresses
The ESXi management network assigned in OneView InstantOn requires contiguous IP addresses. When
assigning IP addresses for the ESXi management network, the Management VM IP address is assigned
first and is the starting IP address. Record the starting IP address on the preinstallation worksheet
You must choose separately the HC380 Management UI and HC380 OneView VM IP addresses on the
ESXi management network so that they do not conflict with the IP addresses assigned by OneView
InstantOn.
When planning the ESXi management network, Hewlett Packard Enterprise recommends that you use
the convention shown in the table.
