ECS 3.6.2.3 Release Notes

ECS Gen3 appliance series

The ECS Gen3 appliance series include:

• EXF900: An all flash object storage solution of hyper-converged nodes for low latency and high Input or Output Operations Per Second (IOPs) ECS deployments. This platform starts at 230 TB RAW minimum configuration and scales up to 2.8 PB RAW per rack.
  NOTE EXF900 with three or more sites in Geo are available only by RPQ.
• 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 480 TB RAW to 6.144 PB RAW per rack.
• 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 3.08 PB RAW per rack.
• EX3000 series: An ultradense object storage solution of hyper-converged nodes for medium to large-sized ECS deployments. This platform starts at a 2.16 PB RAW minimum configuration and scales to 11.52 PB RAW per rack.
