The high-availability status of a device group is usually indicated by the following notation.
The device group can experience a device failure
and still function normally.
N+
The device group has just enough good devices to
function normally. Subsequent failure of a device
in the group can cause the cabinet to shut down.
N
The device group does not have enough good
components to function normally. If a cabinet is
running and goes into an N- cooling state, then the
cabinet is automatically shut down. If a cabinet has
an N- power state, then devices in the group cannot
be powered on. This means that if the cabinet is
running, it continues running, but no additional
devices can be powered on. If the cabinet is off and
comes up in the N- power state, then none of its
devices can be powered on.
N-
headroom
In general, the amount of a computing resource that is available on a system after all
requirements for applications on the system are accounted for.
In
HP Insight Capacity Advisor software
, requirements for applications include the
set for each application.
See also relative headroom.
high availability
See HA.

HP SIM
HP Systems Insight Manager software (HP SIM). HP SIM provides simplified, centralized
management of multiple
and platforms through a web-based, unified interface. HP SIM
provides the platform and framework on which the VSE Management Software products are
deployed. HP SIM provides administrators single sign-on access to
on managed
servers (standalone or partitioned) from a central console.
HP SMH
HP System Management Homepage. HP SMH is a web-based interface that consolidates and
simplifies the management of a single HP-UX server. HP SMH is also available for Linux and
Microsoft® Windows® systems. HP SMH integrates with HP Systems Insight Manager, the
strategic platform for multisystem management.
hyper-threading
Intel® Hyper-Threading Technology. The ability of certain processors to create a second virtual
that allows additional efficiencies of processing. This is not a true multi-core processor, but
it adds performance benefits. True multi-core processors typically deliver much greater
performance than equivalent hyper-threading technology.
iCAP
HP Instant Capacity. The HP Utility Pricing Solutions product that allows you to purchase and
install additional processing power through the use of a two-step purchase model. Initially,
you purchase system components (
, cell boards, memory) at a fraction of the regular price
because 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
price for the usage rights 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.
Earlier versions of iCAP were referred to as Instant Capacity on Demand, or iCOD.
iCAP core
Also referred to as a core without usage rights, a core that is physically installed in an
system but does not have usage rights and is not activated. After obtaining
