Buying guides
Choose the right kit, first time.
Short, opinionated guides on specifying each major layer — what to look for, the common traps, and how the decision shifts with scale.
Choosing a UPS
The heart of power protection — topology and battery chemistry.
- Online double-conversion for DC-grade protection
- Li-ion vs VRLA: footprint & life vs upfront cost
- Size for load + growth + N+1
Precision cooling
Match cooling type to density and room shape.
- CRAC vs CRAH vs in-row vs rear-door
- Containment beats extra tonnage
- Plan for liquid cooling if AI is coming
DG sets & backup power
Your real primary source in Indian grid conditions.
- Size for IT + cooling + losses, with margin
- AMF panels & auto-synchronisation
- Fuel storage, day-tanks & run-time
Racks & cabling
Cheap to get wrong, expensive to redo.
- 42U vs 45U/48U; weight & airflow
- Cat6A copper vs OS2 fibre backbone
- Containment-ready rows from day one
Fire & security
Non-negotiable, and often audited.
- VESDA for early aspirating detection
- Clean agent (Novec/inert) — never water
- Access control down to the rack
DCIM & monitoring
You can't run what you can't see.
- Power, thermal & capacity in one view
- Leak, temperature & humidity sensors
- Integrate with BMS, not bolt-on later
