Flexible entry points enable ECS to rapidly scale to petabytes and exabytes of data. With minimal business impact, an ECS solution can scale linearly in both capacity and performance by adding nodes and disks.
ECS appliance hardware models are characterized by hardware generation. The third-generation appliance series, known as the Gen3 or EX-Series, include three hardware models. A high-level overview of the EX-Series is provided in this section. For complete details, see the ECS EX-Series Hardware Guide.
