The simplest case, a single 1P/1C server, running a single instance of HP-UX, is a standalone system. It is a computer not connected to a network (or is the sole server on a network).

Today, these are probably dedicated machines, perhaps running highly secure or highly specialized applications. For whatever reason, these are systems in isolation. They are either single user machines or if they support multiple users they require directly connected terminals or modem connections.

By nature, these machines are limited in processing resources and therefore not very flexible in configuration so most of the virtualization technologies are not available to them. However, even these machines can benefit from the following virtualization technologies:

  • Integrity Virtual Machines

    Integrity Virtual Machines allow you to share a common set of hardware resources on an HP Integrity Server among multiple operating system instances. The resources are shared on a temporal basis.

  • Volume Management using either:

    • The HP Logical Volume Manager (LVM)

    • The VERITAS Volume Manager (VxVM)

  • Persistent Device Special Files

    Persistent device special files allow you to have multiple physical paths to mass storage devices. Persistent device special files have virtualized hardware paths (called LUN hardware paths) so that a single persistent device special file can represent multiple physical paths to a mass storage device and traffic can be balanced among the physical paths for more efficient data transfer.

  • Common Desktop Environment (CDE)

    CDE allows you to configure multiple (virtual) workspaces using the X Window technology. You can group and organize various types of work into these workspaces and name the workspaces for easy identification.
