Designing for the future.
WHAT CONSTRAINS GROWTH
Power, first Cooling, second Space, last
WHY THAT ORDER SURPRISES PEOPLE
Facilities run out of power and cooling long before they run out of floor space.
WHAT TO PLAN
Power distribution capable of supporting future density Cooling capable of removing the resulting heat Space for additional plant, not only racks
WHAT DENSITY MEANS
Power consumed per rack.
WHAT HAS CHANGED
Equipment has become far denser, and modern workloads more so again.
WHAT THAT MEANS
Facilities designed years ago frequently cannot support modern equipment at full density.
WHAT TO ASK
What power per rack the facility supports.
WHAT TO PLAN FOR
Phased build, so capacity is added as demand appears.
WHY
Building everything at once wastes capital on unused capacity.
WHAT TO AVOID
Filling every rack immediately, leaving no room for growth or maintenance.
WHAT TO MONITOR
Power and cooling utilisation, against capacity.
