Installation and Upgrade Guide

HSx drive Any disk or tape drive connected to an HSx device (for example, an HSJ or HSG). A system
disk on an HSx drive can be shared by several computers in an OpenVMS Cluster environment.

Hyper-Threading Supported on systems that have dual-core processors, this feature provides the ability for
processors to create a second virtual core that allows additional efficiencies of processing. For
example, a dual-core processor with Hyper-Threading active can run four threads.
iCAP Instant Capacity. Supported on cell-based Integrity servers, an HP Utility Pricing Solutions
product whose pricing model is based on purchasing components (processors, cell boards, and
memory). Instant Capacity allows you to purchase and install additional components at a
discount from the regular purchase price, as the usage rights are not included. These Instant
Capacity components are inactive but installed and ready for use. When extra capacity is needed,
you pay the remainder of the regular purchase price for the usage rights (through purchasing
a Right to Use codeword) to activate the components. (If the regular price for the component
is reduced by the time the usage rights are purchased, the remainder price is proportionally
reduced, providing additional savings.) After obtaining usage rights, Instant Capacity processors
can be turned on by the Instant Capacity software or during installation.
Earlier versions of iCAP were referred to as Instant Capacity on Demand, or iCOD.
See also PPU, TiCAP.
iLO See MP.
InfoServer A general-purpose disk storage server (virtual device server). It can make devices available to
client systems on the LAN. Client systems can connect to the virtual devices and use them as
though they are locally attached devices. OpenVMS systems connected to the same LAN can
boot from a virtual drive available from the InfoServer instead of from a local CD or DVD.

Kerberos A network authentication protocol that provides authentication for applications using secret-key
crytpography. Kerberos is automatically installed with the OpenVMS operating system.
layered products Products, including SIPs, provided by HP and third parties that can installed on an OpenVMS
system.
See also SIP.
local area
OpenVMS
Cluster system
A configuration consisting of one or more computers that act as a MOP server and disk server,
and a number of low-end computers that act as satellite nodes. The LAN connects all of the
computers. These computers share a single file system.
local drive A drive, such as a CD, DVD, or disk drive, that is connected directly to a computer. If you have
a standalone computer, it is likely that all drives connected to the system are local drives.
logical CPU An execution thread contained within a core on Integrity servers with Intel Itanium Dual-Core
processors.. With Hyper-Threading enabled, each core can contain multiple logical CPUs.
See also core, Hyper-Threading.

MCOE Mission Critical Operating Environment. The tier of the Operating Environment for OpenVMS
for Integrity Servers that offers everything offered by the Enterprise Operating Environment
(EOE) plus clustering.

media Any packaging agents capable of storing computer software (for example, compact discs,
magnetic tapes, floppy disks, disk packs, and tape cartridges).
