Property Description
whom the Element is purchased, but this is not necessarily
true. The latter information is contained in the Vendor
property of CIM_Product.
Model
The name by which the PhysicalElement is generally known.
Name
The Name property defines the label by which the object is
known. When sub-classed, the Name property can be
overridden to be a Key property.
PackageType
Enumeration defining the type of the PhysicalPackage.
Possible values are:
● 0 = Unknown — Indicates that the package type is not
known.
● 1 = Other — The package type does not correspond to an
existing enumerated value. The value is specified using the
OtherPackageType property.
● 2 = Rack
● 3 = Chassis/Frame
● 4 = Cross Connect/Backplane
● 5 = Container/Frame Slot
● 6 = Power Supply
● 7 = Fan
● 8 = Sensor
● 9 = Module/Card
● 10 = Port/Connector
● 11 = Battery
● 12 = Processor
● 13 = Memory
● 14 = Power Source/Generator
● 15 = Storage Media Package (example, 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 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
