Property Description
• 11 = Battery

• 13 = Memory
• 14 = Power Source/Generator
• 15 = Storage Media Package (e.g., Disk or Tape Drive)
• 16 = Blade
• 17 = Blade Expansion
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 dierent than the MIB's values.
The values Rack through Port/Connector are dened 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 dierently by
inventory systems and diers 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.
SKU
The stock-keeping unit number for this PhysicalElement.
Tag
An arbitrary string that uniquely identies 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 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 from its
containing (scoping) Package and be temporarily unused. The
object still continues to exist and can even be inserted into a
dierent scoping container. Therefore, the key for Physical Element
is an arbitrary string and is dened independently of any placement
or location-oriented hierarchy.
