3PAR InServ E-Class/F-Class Storage Server Physical Planning Manual
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.
4.4 Providing for Service Access
3PAR InServ Storage Server cabinets feature locking rear doors and removable side panels and
fascias to improve access while installing, cabling, and servicing components. Storage server
cabinets can be housed in two sizes (Table 4-3).
