NOTE: This enumeration expands on the list in the Entity
MIB (the attribute, entPhysicalClass). The numeric
values are consistent with CIM's enum numbering
guidelines, but are slightly different than the MIB's
values. The values Rack through Port/Connector are
defined per the Entity-MIB (where the semantics of rack
are equivalent to the MIB's stack value). The other
values (for battery, processor, memory, power source/
generator and storage media package) are self-
explanatory.
A value of Blade should be used when the PhysicalPackage
contains the operational hardware aspects of a ComputerSystem,
without the supporting mechanicals such as power and cooling.
For example, a Blade Server includes processor(s) and memory,
and relies on the containing chassis to supply power and cooling. In
many respects, a Blade can be considered a
Module/Card.
However, it is tracked differently by inventory systems and differs
in terms of service philosophy. For example, a Blade is intended to
be hot-plugged into a hosting enclosure without requiring
additional cabling, and does not require a cover to be removed
from the enclosure for installation. Similarly, a
Blade Expansion
has characteristics of a Blade and a Module/Card. However, it is
distinct from both due to inventory tracking and service
philosophy, and because of its hardware dependence on a Blade. A
Blade Expansion must be attached to a Blade prior to inserting the
resultant assembly into an enclosure.
PartNumber
The part number assigned by the organization that is responsible
for producing or manufacturing the PhysicalElement.
SerialNumber
A manufacturer-allocated number used to identify the Physical
Element.
SKU
The stock-keeping unit number for this PhysicalElement.
Tag
An arbitrary string that uniquely identifies the Physical Element and
serves as the key of the Element. The Tag property can contain
information such as asset tag or serial number data. The key for
PhysicalElement is placed very high in the object hierarchy in order
to independently identify the hardware or entity, regardless of
physical placement in or on Cabinets, Adapters, and so on. For
example, a hotswappable or removable component can be taken
