# Massive unapologetic storage firepower part 4: On the test track with a Forte unit … vaaaaROOOOOOMMMMMMM!!!!!

I am trying to help people conceptualize the experience. Here is a video depicting very fast, very powerful cars and their sound signatures.

This is a good start. Take one of those awesome machines, and turn off half the engine. So it is literally running with 1/2 of its power turned off. Remember this. There will be a quiz. As we flippantly noted in the video, this is face-melting performance. Had I any hair left, it would have been blown way back.
This is (for a number of reasons) a 1/2 configuration of a Forte NVMe storage unit. We’ve said it is quite likely the fastest storage platform in market, not by a little bit. And we are really … really … not kidding.
After conditioning the unit for a few hours, I turned on the parallel file system (BeeGFS), and started doing a customer run. The Forte unit is attached to a Unison unit as a client, over a single (yes, really) 100Gb link. The network traffic is RDMA so it won’t show up on dstat output below.
Watch as I run writes …

The longer tail actually comes from straggling writers/readers. 24 threads, similar performance from 2k to 1024k blocks.
The take home message is that we are filling up the network, and it is our bottleneck.
We are filling the 100Gb network.
With 1/2 our box.
And its 2/3rds idle during the reads, and about 1/2 idle during the writes.
These are very reasonably priced boxen. And available in volume today. Reach out to the day job if you would like more info. More tests soon. Very soon.
