BLR 1 at Whitefield is listed by Nxtra by Airtel at 5.4 MW of IT power across 2,000 racks — 2.7 kW a rack, the second lowest density in this registry. It is the smallest of the operator’s four Bengaluru buildings by power and the second largest by cabinet count, which tells you almost everything about when it was designed. Whitefield is where Bengaluru’s data centre industry started, and its buildings were laid out when a cabinet meant a rack of servers drawing under three kilowatts.

22.7 kW a rack
Two numbers describe this building and a division describes what it is for.
| Facility | kW a rack | Racks |
|---|---|---|
| Nxtra NCR 2, Noida | 2.3 | 1,500 |
| Nxtra BLR 1, Whitefield | 2.7 | 2,000 |
| Nxtra NCR 1, Noida | 3.6 | 1,250 |
| Nxtra DC2, Bengaluru | 5.0 | 4,000 |
| Nxtra MUM 4, Mahape | 11.7 | 3,600 |
| TCS HyperVault, Hyderabad, claimed | above 170 | — |
At 2.7 kW a cabinet this building is space-constrained long before it is power-constrained. Two thousand cabinets occupy the floor area of a 5.4 MW building, where the same load at Mahape density would fit into roughly 460. That inverts the usual Indian data centre problem, where land and power are scarce and cabinets are the thing operators build to fill.
Its commercial life is therefore long and undramatic. Two kilowatts a cabinet serves exactly what a large share of Bengaluru’s enterprise market still buys: racks of servers, storage arrays, network equipment and backup infrastructure for software and services companies in the surrounding EPIP zone. It will not host a GPU. It will keep earning.
India’s installed base is mostly buildings like this one — under six kilowatts a cabinet, profitable, unexciting, and invisible in AI coverage.
Any supplier whose strategy is only AI capacity is ignoring the majority of the sites that actually exist.
3Whitefield: the original corridor
Whitefield is Bengaluru’s first data centre corridor and it is still one of the densest concentrations of IT infrastructure in India, but the new capacity has moved east.
| Neighbour | Position |
|---|---|
| Iron Mountain BLR-1 | 80,000 square feet and about 4 MW in Whitefield, roughly 1.6 miles away |
| STT Bengaluru DC 2 and DC 3 | KIADB EPIP layout in Whitefield, within a few miles |
| CapitaLand Bangalore 01 | inside International Tech Park Bangalore in Whitefield |
| NTT Bengaluru facilities | including a newer campus near the airport with 100 MW planned |
| The EPIP zone itself | Bengaluru’s original export promotion industrial park, surrounded by software campuses and the customers they house |
| Why the growth moved | Whitefield is built up. Hoskote, further east on the highway, has the land and is where Karnataka is planning a 500 MW data park |
That is the shape of the market in one city. The customers stayed in Whitefield; the capacity is moving to Hoskote, about 30 kilometres east, because land, substations and water are available there and are not here.
For an operator this is the familiar dilemma. An old building in the right location with the wrong density is worth keeping for its contracts and cross-connects, and worth nothing for growth. Nxtra’s answer, visible in its own four cards, has been to build the new capacity at Hoskote and leave Whitefield to run.
4Bengaluru’s four buildings
The cluster arithmetic is the useful frame, and Bengaluru turns out to be the operator’s most rack-heavy cluster relative to its power.
| Facility | Location | MW | Racks | kW a rack |
|---|---|---|---|---|
| DC2 | locality not stated | 20 | 4,000 | 5.0 |
| BLR 2 | Hoskote | 14 | 2,800 | 5.0 |
| BLR 3 | Hoskote | 6 | 1,000 | 6.0 |
| BLR 1 | Whitefield | 5.4 | 2,000 | 2.7 |
| Total | four buildings | 45.4 | 9,800 | 4.6 |
Forty-five megawatts across 9,800 racks. Compare that with Nxtra’s Mumbai cluster at 71 MW across 6,900 racks. Bengaluru has 42% more cabinets on 36% less power. The same operator, two cities, and two very different physical estates.
That is what a mature software market looks like in infrastructure terms: many enterprise tenants in many small footprints, rather than a few hyperscalers in dense halls. Karnataka’s government estimates the state has about 400 MW of data centre capacity today, which would put Nxtra at roughly 11% of the state.
