Form rows of racks or cabinets perpendicular to air conditioners. This formation facilitates an
unobstructed flow of heated air down the aisles to the air conditioner return ducts. Heated air must
not be forced to travel over or between the cabinets to get to the air conditioner return ducts. Doing
so could heat the air in the cold aisles. Ensure that any free-standing equipment does not allow air
to flow between the hot and cold aisles.
A cold aisle has perforated floor tiles or grates that enable cold air to rise from the raised floor
whereas the hot aisle has no tiles or grates so that hot air and cold air do not mix. Seal cable
cutouts in both hot aisles and cold aisles to increase under the floor pressure and to eliminate cold
or hot air redirection. To further optimize the airflow in hot and cold aisles, install blanking panels
at the front of all unused cabinet spaces so that hot air does not recirculate to the system’s cold air
inlet.
Providing for Service Access
HP P10000 3PAR Storage Systems are housed in 2M (40U) cabinets that measure 76.75 in. (195
cm) x 32.65 in. (82.9 cm) x 35.62 in. (90.5 cm). Cabinets feature locking rear doors and
removable side panels to improve access while installing, cabling, and servicing components.
When establishing an operating site for an storage system, provide for adequate access to cabinets
by following the access area recommendations in Table 12 (page 25).
NOTE: The V400 and V800 Storage Systems have circuit breakers located at both the front and
rear of the system. It is necessary to maintain access to both the front and rear circuit breakers.

NOTE: HP 3PAR cabinets do not require side access during operation. However, during
installation, one side of the cabinet must be removed to access the PDU power cords.
Meeting Environmental Conditions
It is recommended that you maintain a controlled environment requiring a high degree of cleanliness,
close control of temperature and humidity, and infrequent personnel access.
CAUTION: The storage system operating environment must be free from continuous vibration
and from dust and other environmental contaminants.
In addition, the operating site must comply with the following environmental specifications (Table 6
(page 12)):
