Property Description
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 (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 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.
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
