# Ocient Architecture

> Learn about Ocient architecture, designed to support high-speed analytics on massive datasets.

The Ocient Hyperscale Data Warehouse™ is a modern, scalable distributed system capable of enabling complex OLAP-style analysis on the world’s largest structured and semi-structured datasets using SQL. It features a purpose-built storage and an input and output layer designed for highly parallel interaction with modern NVMe SSD drives in a Compute Adjacent Storage Architecture® (CASA) that leverages erasure coding for cost-efficient reliability.

On top of this is a fully integrated execution engine and optimizer that were each built from scratch using modern design principles in a manner that deeply integrates with the storage and I/O layer. The result is a state-of-the-art data warehouse that can deliver outstanding, and even unprecedented, analytical capability on datasets with record sets numbering in the trillions, quadrillions, and beyond.
