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.
PropertyOwnershipTag

SecurityBreach
An enumerated, integer-valued property indicating whether a
physical breach of the Frame was attempted but unsuccessful
(value=4) or attempted and successful (5).
Possible values are:
• 1 = Other
• 2 = Unknown
• 3 = No Breach
• 4 = Breach Attempted
