It looks very different.

You can't use the lead-acid UPS systems because these peaks are ultra-fast.

These transients, they have tens of amps per microsecond.

And essentially this slew rate of the DIDT that you need for bringing these GPUs switched on, the latency increases the longer the cable is because of the inductance.

And that's basically the slew rate that limits.

It impacts it, yeah.

So essentially you may have what is on paper

Great metrics on the ratings.

Okay, power taken care of, but actually that's just static loads.

For dynamic loads, there were no metrics.

There's no continuity of compute metric.

You can call an uptime of powers available at that site, but actually it's breaking when the GPU needs it.

So you are having brownouts, you're having blackouts.

So coming back to fast energy storage, you need microsecond level peak response to just like come on as fast as you can.

You can recharge it again as fast as that window is available.

So there's 20 milliseconds of like overshooting by 100% or something like that.

And then there's another like maybe 100 milliseconds or a few seconds.

So you know how the workloads are trained, right?

So you have the compute cycle and then you have a communication cycle and then you have like a checkpoint cycle with the memory.

So each time you're going up and down, it's a repetitive pattern.
