Architecture of an installation  11  
 
 
DHCP server 
A Dynamic Host Configuration Protocol (DHCP) server is required to provide systems with network 
configuration parameters for use during network deployments. If deployments are booted through PXE, 
then the DHCP server can also provide boot information. If the Rapid Deployment Pack is used, a 
separate DHCP server for PXE boot is not required. 
TFTP server 
When PXE booting is used, a TFTP server must provide the booting systems with the files that are 
necessary to properly boot. For Solaris this server includes 
pxegrub,
 the GRUB menu file 
menu.lst,
 
the Solaris 
multiboot
 program, and a miniroot. The DHCP/PXE server often hosts the TFTP server. If the 
Rapid Deployment Pack is used, a separate TFTP server is not required. 
JumpStart server 
A JumpStart server is a networked system that provides JumpStart profiles and sysidcfg(4) files to clients 
during network deployments. A profile and 
sysidcfg
 file provide all the system configuration 
information necessary to complete an installation, reducing the amount of interaction required. 
Profiles and 
sysidcfg
 files are typically exchanged through NFS. For information about setting up a 
Install server 
An install server is a networked system that contains a copy of the Solaris installation media that it makes 
available to other systems on the network through NFS. During a network deployment, a client obtains the 
Solaris operating environment software from the install server instead of from the physical media such as 
a CD or DVD. For information about setting up an install server, see “Install server preparation.” 
Deploying ProLiant servers 
While you can use traditional Solaris deployment mechanisms to deploy ProLiant servers, some 
requirements are ProLiant-specific. In addition, you can use some HP technologies to enhance Solaris 
deployments. The following sections provide an overview of these requirements and technologies. 
Information in the following sections is for use with network-based or other advanced deployment 
methods. For basic interactive installation information, see “Basic installations.” For more information 
about the tasks, see “Deployment tasks.”
