Dell EMC Atmos

Dell EMC Atmos is an object-based cloud storage platform that was released in November 2008 by EMC. Atmos is targeted toward service providers and large enterprises that want to build private clouds. Dell EMC continues to offer Atmos along with its Elastic Cloud Storage (ECS) product, which is considered the successor to Atmos.

Atmos is sold as an active-active architecture and single global namespace that provides multisite data access and efficient geoprotection. It supports Amazon Simple Storage Service (Amazon S3) and Atmos REST-based APIs. Its extensible metadata capability enables policy-based replication and information lifecycle management. While Dell EMC Atmos provides higher latency, it has limited file-based access (CIFS and NFS).


EMC first unveiled Atmos in 2008 as a combination hardware-software offering designed to deliver internet-based applications on a massive scale in a cloud infrastructure. Originally code-named Maui, the software portion was built to manage petabyte-level data growth.

The product could be purchased as software running on x86 servers virtualized with VMware's hypervisor or as EMC traditional hardware combining x86 servers with high-capacity, low-cost Serial ATA (SATA) drives. The product was targeted at media, entertainment, telecoms and internet providers.

In September 2017, Dell acquired EMC, and Atmos became part of the Dell EMC enterprise IT division.

Different editions

EMC Atmos Cloud Delivery Platform (ACDP) is add-on software for Atmos that provides self-service access for cloud deployments. The software helps service providers and businesses add a cloud storage offering to their services. ACDP has a user-friendly interface for identity provisioning, bandwidth reporting, and a storage resource consumption metering module to enable chargeback for private clouds and billing for public clouds.

EMC Atmos Virtual Edition supports content-rich applications and provides application developers and users with instant access to storage, with minimal IT provisioning. The product supports REST, Simple Object Access Protocol (SOAP) web services with APIs across Dell EMC Atmos and Atmos-powered external clouds. It provides policy-based information management and object metadata, as well as multi-tenancy and a unified namespace.

EMC Atmos GeoDrive is a software add-on product -- available to licensed Atmos customers -- to enable simple and fast access to an Atmos cloud. It behaves like local storage, creating a Windows drive or Linux mount point to connect to an Atmos private or public cloud, where users can drag and drop to share files.

Dell EMC Elastic Cloud Storage

Elastic Cloud Storage, formerly Project Nile, was introduced in 2014 as the successor to the EMC Atmos cloud storage platform. Initially, ECS was a combination of the ViPR automated provisioning tool and ScaleIO, a distributed scale-out block storage architecture that EMC Corp. acquired in 2013.

ECS is a software-defined, cloud-scale, object storage platform that combines commodity infrastructure with the reliability of traditional arrays. It provides protocol support for unstructured data workloads, both file and object, on a storage platform.

at EMC, discusses how ECS addresses
traditional storage systems and the
public cloud.

The product aims to deliver capacity, rather than performance storage, much like Amazon S3. Elastic Cloud Storage used the 2.0 release of ViPR to bring wider support for managed platforms from a range of vendors, including Hewlett Packard Enterprise, Hitachi Vantara, IBM, Oracle and SolidFire, while extending support to most of EMC's products such as Isilon, ScaleIO, VMAX and VNX.

ECS version 2.2.1 was released in May 2016. ECS 3.0 was released in September 2016, while ECS 3.1 was released in August 2017.

Elastic Cloud Storage competes with Amazon S3, Google Cloud Storage and Microsoft Azure Blob Storage.
