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.
About Terabits
A terabit (Tbit) = 10¹² bits (SI). Submarine cable capacity: 2Africa cable (2024) designed at 180 Tbit/s; MAREA (2017) at 160 Tbit/s. Data-centre interconnects use 400 Gbit/s (0.4 Tbit/s) per link. PCIe 6.0 ×16 delivers ≈0.5 Tbit/s aggregate. NVMe RAID arrays with 100+ PCIe 5.0 SSDs approach 1 Tbit/s aggregate sequential read. 1 Tbit = 10¹² bits = 125 GB.
