Quarterly Tasks; Biennial Tasks - Oracle StorageTek SL3000 System Assurance Manual

data center, for any purpose, should be equipped with High Efficiency Particulate Air
(HEPA) filtration. Inadequately filtered equipment cannot arrest smaller particles, but
rather simply agitates them, degrading the environment they were meant to improve.
It is also important that mop-heads and dust wipes are of appropriate non-shedding
designs.
Cleaning solutions used within the data center must not pose a threat to the hardware.
Solutions that could potentially damage hardware include products that are:
Ammoniated
■
Chlorine-based
■
Phosphate-based
■
Bleach enriched
■
Petro-chemical based
■
Floor stripper or re-conditioners
■
It is also important that the recommended concentrations are used, as even an
appropriate agent in an inappropriate concentration can be potentially damaging. The
solution should be maintained in good condition throughout the project, and excessive
applications should be avoided.

Quarterly Tasks

The quarterly statement of work involves a much more detailed and comprehensive
decontamination schedule and should only be conducted by experienced computer
room contamination-control professionals. These actions should be performed three to
four times per year, based on the levels of activity and contamination present. All
room surfaces should be thoroughly decontaminated including cupboards, ledges,
racks, shelves and support equipment. High ledges and light fixtures and generally
accessible areas should be treated or vacuumed as appropriate.
Vertical surfaces including windows, glass partitions, doors, etc. should be thoroughly
treated. Special dust cloths that are impregnated with a particle absorbent material are
to be used in the surface decontamination process. Do not use generic dust rags or
fabric cloths to perform these activities. Do not use any chemicals, waxes or solvents
during these activities.
Settled contamination should be removed from all exterior hardware surfaces
including horizontal and vertical surfaces. The unit's air inlet and outlet grilles should
be treated as well. Do not wipe the unit's control surfaces as these areas can be
decontaminated by the use of lightly compressed air. Special care should also be taken
when cleaning keyboards and life-safety controls. Specially treated dust wipes should
be used to treat all hardware surfaces. Monitors should be treated with optical
cleansers and static-free cloths. No Electro-Static Discharge (ESD) dissipative
chemicals should be used on the computer hardware, since these agents are caustic
and harmful to most sensitive hardware. The computer hardware is sufficiently
designed to permit electrostatic dissipation thus no further treatments are required.
After all of the hardware and room surfaces have been thoroughly decontaminated,
the access floor should be HEPA vacuumed and damp mopped as detailed in the
Weekly Actions.

Biennial Tasks

The subfloor void should be decontaminated every 18 months to 24 months based on
the conditions of the plenum surfaces and the degree of contaminant accumulation.
