•Are there air conditioning or power requirements that need to be met? See the documentation that comes with server hardware for this kind of information.
•Have you been thinking about upgrading elements such as cables, switches, and power supplies? Now may be a good time to do it.
•Are your TCP/IP network and subnets configured to support the services and servers you want to deploy?
Define Server Setup Infrastructure Requirements
The server setup infrastructure consists of the services and servers that need to be set up early because other services or servers depend on them.
For example, If you will use Mac OS X Server to provide DHCP, network time, or BootP services to other servers you’ll be setting up, the server or servers that provide these services should be set up and the services running before you set up servers that depend on those services. Or if you want to automate server setup by using setup data stored in a directory, both DHCP and directory servers must be set up first.
The amount of setup infrastructure you require depends on the complexity of your site and what you want to accomplish. In general, DHCP, DNS, and directory services are desirable or required for
•The most fundamental infrastructure layer comprises network services like DHCP and DNS.
All services run better if DNS is on the network. If you’re not hosting DNS, work with the administrator responsible for the DNS server you’ll use when you set up your own servers.
Setting up DHCP will reflect the physical network topology you’ll be using.
•Another crucial infrastructure component is directory services, required for sharing data among services, servers, and user computers. The most common data you need to share is for users and groups, but configuration information such as mount records and other directory data is also shared. A directory services infrastructure is necessary when you want to host
Here is an example of the sequence in which you might set up a server infrastructure that includes DNS, DHCP, and directory services; the services can be set up on the same server or on different servers:
1Set up the DNS server.
2Set up DHCP.
3Configure DHCP to specify the DNS server address so it can be served to DHCP clients.
4Set up a directory server, including Windows PDC service if required.
