A physical server is a computer used to provide data to other computers or systems on a local area network (LAN) or a wide area network (WAN) over the internet. While any computer can be configured as a server, most production servers use specialized server hardware mounted in racks and installed in a data center. A physical server can be used for a number of applications, including databases, applications, network management, email, directory services, etc. The lifecycle outlined here applies to any physical server equipment irrespective of its application.

Application

This lifecycle is typical for the following asset classes:

• Physical Servers of all classes

Typical Lifecycle for Physical Servers

• Phase 1: Hardware Requested & Approved
  During this phase, a need for the server is determined and a decision is made to deploy a physical server rather than a VM. The specifications for the equipment are determined, quotes are obtained, approvals are collected from appropriate stakeholders, and a supplier is selected. In some cases, the "supplier" may be internal if, for example, an existing device can be repurposed or one is located in another department.

• Phase 2: Order Placed & Equipment Acquired
  If the equipment is being acquired from a third party, an order is placed. If the equipment is being transferred internally within OIT or from another department, the required documentation is prepared and executed. This phase ends at the point where the hardware has been delivered and is ready for configuration.

• Phase 3: Hardware Tested & Installed
  The equipment must be compared to the original specifications and acquisition documents to confirm that it matches the original requirements. Any required assembly and configuration is done during this phase. This includes operating system software, application software and services, databases, network connections, user definition and security rules, and arrangements made for backups and disaster recovery. When all configuration steps are complete, a system test is performed on the server in place to ensure it meets all client requirements. This phase ends when the server is ready to be deployed into production.

• Phase 4: Equipment in Service & Maintained
  This phase represents the useful production life of the server. Throughout this phase, the equipment will undergo periodic maintenance, upgrades, failures and fixes. At some point, the usefulness of the server will come to an end and plans need to be made to take it out of service. (Normally, these plans are made well in advance of the decommissioning of the server.)

• Phase 5: Equipment Decommissioned
  When the equipment is no longer needed, either because it is being replaced by a newer system or it no longer serves any useful function, it is decommissioned. Decommissioning is usually a fairly complex process when the server is being replaced. If the services provided by the server are no longer needed then decommissioning can be as simple as powering the system off. Once offline, the server is either deinstalled and disposed of, or made available for other purposes. Plans for decommissioning are generally made well in advance of the actual deinstallation of the equipment.
