ZettaScaler is a series of Japanese supercomputers using processors designed by PEZY and liquid cooling systems designed by ExaScaler.

Overview

ZettaScaler supercomputers are constructed using dense server aggregates called 'Bricks'. The system is cooled using enclosures containing a number of bricks. The cooling system is designed by ExaScaler and makes use of 3M's Fluorinert Electronic liquid which is an electrically insulating fluorocarbon-based inert liquid.

ZettaScaler-2.x

With the introduction of the ZettaScaler-2.x, PEZY has redesigned the Brick. PEZY moved to an advanced 3D packaging technology using ThruChip Interface (TCI) to interconnect the DRAM to the processor which uses wireless near-field inductive coupling instead of the traditional TSV.
