HP Insight Control Server Provisioning 7.2 Update 2 Installation Guide

5 DHCP server setup
Insight Control server provisioning requires a DHCP server to provide IP addresses to target servers
during the provisioning process. Insight Control server provisioning has a DHCP server internal to
the appliance you may use, or you can set up your own DHCP server external to the appliance.
NOTE: A DHCP server is still required for Gen8 servers. Even if PXE is not used, a DHCP server
is needed to bring the server into maintenance and contact the appliance. Once that communication
is established, you can run build plans with static IP addressing provided.
Deciding whether to use a DHCP server internal or external to the appliance
Insight Control server provisioning has a DHCP server internal to the appliance you may use, or
you can set up your own DHCP server external to the appliance. Consider the following to choose
which method is better for your facility.
1. Consider what your DHCP requirements are when provisioning servers: IP address only or
extended DHCP options.
IP address only
In this configuration, your DHCP server only needs to provide standard networking information
(IP address, net mask, etc.) to the target servers. This configuration can be used if your
environment meets all the following conditions:
• You will not PXE boot any servers
• Your target servers are all HP ProLiant Gen8 series or newer
• You will use the embedded HP Intelligent Provisioning features of your ProLiant servers
(no PXE)
• You will use iLO IP addresses and credentials to add servers to the appliance.
Extended DHCP options
In this configuration your DHCP server must provide standard networking information, plus
additional options so the target servers can PXE boot from the appliance into the required
service OS. The extended DHCP configuration is required if your environment meets any of
the following conditions:
• You will PXE boot servers (this includes PXE booting to add servers to the appliance)
• You have target servers earlier than Gen8 series
• You have Gen8 series target servers but will not use Intelligent Provisioning
• You do not want to use iLO to add servers to the appliance
2. Next, decide between using the DHCP server internal to the appliance or configuring an
external DHCP server.
DHCP server internal to the appliance
Your Insight Control server provisioning appliance comes with a built-in DHCP server that is
easy to configure and use, and provides all the extended information required for PXE booting.
• Configures easily via the appliance Settings screen
• Provides addresses only for the subnet your appliance is in
• Supports optional information, such as DNS and gateway
• Will always provide extended information required for PXE booting target servers.
External DHCP server
An external DHCP server might make sense in the following cases:
