About Zettabits
A zettabit (Zbit) = 10²¹ bits (SI). Global internet traffic crossed 1 ZB/year ≈ 2017; projected to reach 72 Zbit/year by 2030. IDC estimates global data created/consumed could reach 1,400 Zbit/year by 2025 (mostly transient). The theoretical capacity of all installed submarine fibre, running simultaneously at state-of-the-art spectral efficiency, approaches several Zbit/s. 1 Zbit = 10²¹ bits = 125 EB.
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.
