What this part means

the computing.

Its job in the formula

L is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

In practice, computing L for the Photonic Fabric Module runs into a wall immediately, and the wall is worth describing precisely rather than waved past.

The passage around this formula

That is a clean, falsifiable test in principle. In practice, computing L for the Photonic Fabric Module runs into a wall immediately, and the wall is worth describing precisely rather than waved past. BWoptW_{\text{opt}} is at least partially available — the module’s 7.2-terabit-per-second optical connectivity figure and the appliance’s 32-terabyte pooled capacity are…
