The MicroLink Pod on Vertiv MegaMod HDX

The Pod is a factory built 2 MW data centre delivered as two 45 ft HC containers. Container 1 is the IT row, nineteen rack positions. Container 2 is the power and cooling module, split by a solid wall with the cooling and heat recovery plant on one side and the low voltage power plant on the other. It is designed to sit at an energised industrial host partner and return its heat.

The unit, as designed

Cooling is two loops meeting at the CDU. A treated stainless steel secondary network carrying PG25 runs from the CDU along the row and into the cold plates at each compute rack. A facility loop carries the heat from the CDU to the heat recovery exchangers, and on to the external dry coolers. The dry coolers are a site bolt-on and are always present, because the Pod must reject its full load even when the host takes none.

Power lands once, at a single low voltage interface on Container 2 at 480 VAC, and is distributed from a 4000 A board to the overhead busway in the IT pod and to the mechanical plant. Transformers, medium voltage switchgear and standby generators are site bolt-ons, sized to the whole site rather than to one Pod. The transfer switch sits in the genset package, outside the unit.

The cooling plant is N+1 throughout. The CDU, the heat recovery exchangers and the facility water pumps are redundant pairs manifolded in parallel across a 0.9 m central aisle, so either row can carry the load.

02 · Clarification

This is how the Pod maps onto what Vertiv already builds. Please correct us.

The mapping, element by element

Gap
MegaMod HDX stops at 1.25 MW

Compact is max 13 racks, up to 1.25 MW. The Pod is 19 racks at 2 MW. Combo jumps to 144 racks and 10 MW. Nothing sits at 2 MW.

Check
Density published at 50 to 100+ kW

The Pod runs 15 compute racks at 120 to 130 kW each. We sit above the published band. What is the real ceiling?

Gap
HDX is not an ISO container

The Pod is two 45 ft HC ISO containers, moved by road, rail and sea on standard handling. Vertiv modules are sized for service clearance, not the ISO envelope.

Confirm
CoolChip CDU2300 fits the Pod

2,300 kW covers 2 MW at N. Two of them gives the N+1 pair in the BoD, manifolded in parallel. Direct match, no adaptation.

Confirm
PowerBar is our overhead busway

Named in the HDX component set. Busway along the row with a tap and drop into each rack, fed from the riser out of Container 2.

Confirm
CoolChip Fluid Network Rack Manifolds

These are the secondary fluid branches at each rack: isolation, flow control, leak prevention. Already a Vertiv part.

Confirm
Buffer tank thermal backup

HDX carries a buffer tank so GPU clusters hold stable through maintenance and load transitions. That is the buffer vessel in the BoD, same job, same reason.

Confirm
Vertiv Unify is the BMS

Power, thermal and building management in one interface. Maps to the controls and BMS cabinet in the power half.

Confirm
OCP compliant racks

The BoD reference envelope is 600 by 1200 by 2077 mm, bus bar fed by power shelves. Vertiv already ships OCP compliant racks.

Check
Distributed redundant power

HDX keeps running if one module goes offline. The Pod is N+1 on cooling. We need to see how the two philosophies line up at 2 MW.

Gap
No UPS in the Pod BoD

Power lands at 480 V, goes to a 4000 A board, then to busway. There is no UPS and no ride through anywhere. HDX assumes a Liebert APM2. This needs a decision.

Gap
No heat recovery in MegaMod

But Vertiv does sell heat recovery chillers at 70 degrees C for district heating. It is not a new category for you, it is a product left out of this one.

Confirm
Dry coolers stay a site bolt-on

Always present, sized for full rejection at worst case ambient. The Pod must reject its whole load even when the host takes none.

Check
PowerDirect in-rack DC

Vertiv already ships an in rack DC power system. This is the thread that runs to the 800 V DC pilot and to the Edge cabinet.

Where MegaMod HDX sits

Compact is a maximum of 13 racks and up to 1.25 MW. Combo is a maximum of 144 racks and up to 10 MW. Both run hybrid direct to chip liquid cooling with air, distributed redundant power, and a buffer tank thermal backup. The Pod at 19 racks and 2 MW falls in the gap between the two, and two compacts together would give 26 racks and 2.5 MW. There is no 2 MW unit in the published range.

03 · Questions

Eleven questions. Six of them shape the Pod.

Mark each one yes or no and leave a comment.

The eleven questions

01
Stretch HDX to 2 MW

Compact tops out at 1.25 MW and 13 racks. Can it carry 19 racks at 2 MW, or does a 2 MW size have to exist?

Architecture
02
Fit out into 45 ft HC ISO

Will Vertiv build into two 45 ft HC ISO containers, or must we take a Vertiv enclosure and lose standard container handling?

Architecture
03
UPS or no UPS at 2 MW

The Pod sits behind site gensets and an energised host. Does it need a UPS at all, and what is your recommendation?

Architecture
04
Heat recovery in the Pod

Will you supply and co-engineer the two heat recovery exchangers on the facility loop and the host interface?

Architecture
05
Real density ceiling

You publish 50 to more than 100 kW per rack. We need 120 to 130 kW. Where does the number actually stop?

Architecture
06
Two container split

Container 1 is the IT row. Container 2 is cooling and power either side of a solid wall. Can HDX be arranged that way?

Architecture
07
CDU count and temperatures

Two CDU2300 at N+1 for a 2 MW pod. Confirm, and give us the facility loop supply and return temperatures.

Sizing
08
70 degrees C chiller relevance

Your heat recovery chillers deliver 70 degrees C. Our facility loop runs below 41 degrees C. Is that a lift we want, or not?

Sizing
09
Buffer tank volume

What volume does the HDX buffer tank carry at 2 MW, and what ride through does it actually buy on a swinging GPU load?

Sizing
10
PowerDirect to 800 V DC

Is the in rack DC system a path to the 800 V DC architecture, and can it land in the Pod as well as the block?

Sizing
11
Price and lead time, pod one

Indicative price for the first pod, the factory slot, and how the unit price behaves across a fleet of them.
