Introduction
1-1 Overview
Supermicro's SC826 chassis maximizes the storage capacity of a 2U form factor
by o󰀨ering twelve hot-swappable hard drive bays. It is ideal for data storage
applications. The chassis design optimizes every aspect of interior space, without
compromising superior cooling and is equipped with a redundant power supply.
