Considerations for multiple system installations
When integrating a zEC12 into an existing multiple-system environment, or when adding additional
systems to an installed zEC12, consider the following factors:
v Thermal interactions
Although computer room floor space is valuable, for optimal cooling, it is recommended that zEC12
servers have a 1168 mm (46 in) aisle between rows of systems to reduce surrounding air temperature.
See "Cooling recommendations for the room" on page 42.
v Floor placement
zEC12 must be precisely placed for the cable openings to match the floor cutouts. There is zero
tolerance for variance from the frame positioning in relation to the floor tiles.
v Floor loading
When trying to optimize floor space utilization, floor loading weight distribution rules may be
inadvertently violated by overlapping weight distribution areas of adjacent machines. Obtain the
services of a qualified structural engineer if you are uncertain of the floor load assessment for your
computer room.
