If your site has a raised oor, consider the follo
wing factors:
■
The raised oor must be built of noncombustible materials.
■
Treat concrete suboors to prevent them from releasing dust.
■
Conrm there is positive air pressure below the raised oor to verify adequate
airow.
■
The raised oor clearance must be adequate to accommodate cables. Remove all
unused cables from the area below the raised oor to prevent these areas from
becoming dust and dirt traps.
■
Eliminate sharp edges on oor cutouts to avoid damage to cables.
■
Apply sealant to raised-oor cable openings to prevent chilled air from escaping.
■
For metallic raised oor structures, it is a safety hazard to expose metal or highly
conductive material at ground potential to the walking surface.
Although raised oors are preferred, the storage system can be installed on non-raised
oors. In these environments, overhead cabling can be used to provide power to the
storage system. Installation planning, cable length, and rack location in relation to the
cable openings on the rack are critical to installations that use overhead cabling.
Floor covering and cutouts
Do not use carpeting, including antistatic varieties, because they can shed dust over time
that can cause problems with the storage system.
If your computer room has carpeting, place static discharge mats so that personnel must
walk across them before touching any part of the storage system. Failing to comply with
this precaution can damage the equipment through static discharge.
If your computer room uses oor cutouts to route power and data cables, position the
cutouts toward the center of the rack. If this is not possible, position the cutouts o-
center from the rack as long as the cutout is within the allowable range and allows
smooth routing and entrance of cables. Check the relationship between the position of
the cutout and the cable openings on the rack.
Meeting environmental conditions
For optimal performance, the storage system requires controlled environmental
conditions.
Hitachi recommends that you maintain a controlled environment, with a high degree of
cleanliness and close control of temperature and humidity. The storage system operating
environment must be free from continuous vibration, dust, and other environmental
contaminants.
Keep the location as free of airborne particulates as possible. To eliminate obvious
sources of particulates, do not permit anyone to eat, drink, or smoke near the storage
system. Do not place the storage system close to a copier or printer that can emit toner
and paper dust.
