About Petabits
A petabit (Pbit) = 10¹⁵ bits (SI). Major internet exchange points (DE-CIX, AMS-IX) handle peak traffic of multi-Tbit/s, accumulating Pbits per hour. Bell Labs (2022) achieved 1.02 Pbit/s over a single fibre pair. CERN LHC distributes ≈ 720 Pbit/year through the WLCG computing grid. 100 wavelengths at 800 Gbit/s each = 80 Tbit/s per fibre; ≈13 such fibres = 1 Pbit/s. 1 Pbit = 10¹⁵ bits = 125 TB.
About Pebibits
A pebibit (Pibit) = 2⁵⁰ bits (IEC 80000-13). Intel LA57 5-level paging extends virtual addressing to 57 bits = 128 PiB = 1 Pibit of byte-addressable virtual memory space per process. The Frontier supercomputer (ORNL, 2022) has ≈700 PiB = 5,600 Pibit of total Lustre storage. AMD EPYC Milan-X supports up to 52-bit physical addresses (4 PiB). 1 Pibit = 2⁵⁰ bits = 128 TiB.
