Dell EMC ECS EX Series User Manual

Introduction
This guide describes the hardware components that make up the ECS appliance Generation 3
(Gen3) hardware models.
ECS Gen3 appliance series
The ECS Gen3 appliance series include:
l
EX500 series: A dense object storage solution of hyper-converged nodes for small to medium-
sized ECS deployments.
The EX500 supports node expansion in increments of one when the capacity is the same as the
previous node. If the capacity is different from the previous node when expanding, EX500
supports expansion in a minimum of five-node increments. The recommended expansion is five
nodes. The EX500 series supports from 5 to 16 nodes per rack. With different drive sizes/
quantity and the flexibility of node additions, this platform can scale from 480TB RAW to
4.6PB RAW per rack.
l
EX300 series: A dense object storage solution of hyper-converged nodes for small to medium-
sized ECS deployments. With different drive sizes and the flexibility of single node addition,
this platform can scale from 60 TB RAW to 1.5 PB RAW per rack.
l
EX3000 series: An ultra-dense object storage solution of hyper-converged nodes for medium
to large-sized ECS deployments. This platform starts at a 2.2 PB RAW minimum configuration
and scales to 8.6 PB RAW per rack.
Note: In this document, the term
node is used interchangeably with server , and the term appliance
refers to a cluster of nodes running ECS software.
