Term Definition

HPVM Hewlett Packard Virtual Machine, internal code name for Integrity VM

Hypervisor A hypervisor is a module which allows multiple OS instances to run on a single hardware

platform. In Integrity VM, the PMAN is the hypervisor.

I/O (Accelerated, Direct, Virtual) Accelerated, Direct, and Virtual I/O refer to the three different I/O models for Integrity VM.

Virtual I/O refers to standard drivers used in the guest, which rely on Integrity VM to emulate

registers to allow the Virtual I/O to execute without modification in the Guest. Direct I/O refers

to specially modified drivers, which run in the Guest and have direct access to the physical

hardware below. This results in higher performance than VIO but does not support the sharing

of the hardware between multiple guests. Accelerated I/O refers to specially modified drivers,

which run in the Guest and Host and allow the sharing of the hardware between guests but

perform better than VIO.

VIO, Virtual IO VIO or Virtual IO refers to the unchanged driver stack in an Integrity VM, which relies on the host

to provide register emulation to run unmodified.

Virtual NIC A virtual NIC is the NIC which is seen by a guest in the Integrity VM environment. The virtual NIC

in the guest looks like a NIC in the normal operating environment for the various applications

running on the guest, but in actuality may be one of many interfaces from various guests

sharing a single physical NIC in the host environment.

Virtual switch, vswitch The vswitch, or virtual switch, is the Integrity VM module which emulates an Ethernet switch. This

function is necessary in order for the Integrity VM guests to share via VIO a common physical NIC

on the Host. The switch performs similar functions as a real switch with the main function being

routing packets between the Guests, Host, and the wire (through the physical NIC).

VMSAN Virtual Fibre Channel HBA on HP-UX Integrity VM 11i v3 1003 guest that provides a FC device for

SAN management provisioning at the guest.
