STT GDC Pune 1 is 9 MW, the smallest of five Pune building cards. On its own that is unremarkable. It carries weight because of what it does to the arithmetic: 9 + 15 + 15 = 39 MW, which is the only combination of cards that reconciles to the operator’s 40 MW, three-facility headline — and the rounded 40 is what the page says. No stage, rack count, floor area or PUE is published. This record is a small building holding up a large argument.

2Why nine megawatts matters

The Pune portfolio has four published capacities and no reconciliation. This card is one of the three that closes it.

Only one three-card arrangement lands within a megawatt of 40. It happens to be the three smallest buildings, which is also the arrangement that leaves the two largest as expansion — exactly what a page describing an operational and expanding footprint should look like.

None of this is proof. But it is the difference between a portfolio that is incoherent and one whose structure is recoverable from published numbers, and the second is more likely.

3What a 9 MW building is

Nine megawatts is small enough that its role in a portfolio is usually network and enterprise rather than hyperscale.

Bracketing 9 MW
Assumed densityRacksTypical role
5 kW a rack1,800enterprise colocation, DR, storage
8 kW a rack1,125standard market build
12 kW a rack750a single accelerated-compute hall, if cooled

At this size a building cannot serve a hyperscaler, and it does not need to. Pune’s demand is automotive, manufacturing, financial services and a growing GCC base — customers who want 200 to 800 kilowatts each, not 20 MW.

That is why removing it from the portfolio would matter more than its 11% share suggests. The three small Pune buildings are the ones that serve the customers the city actually has.

The one question
Is Pune 1 operating, and what is its rack count and design density
Why they will answer it
Pune demand is mid-size enterprise and those tenants need small halls, not 24 MW buildings

5Limits and open questions

  • No stage. The card does not say whether the building exists.
  • Basis unresolved. 9 MW could be IT, gross or a design ceiling.
  • No racks, floor area or PUE. Density cannot be computed.
  • The reconciliation is an inference. This card matters because of a reading, not a statement.
  • Single source. No directory carries the 9 MW independently.
  • What would close it. A stage. One word would make this a facility record rather than a card.
