EMC Storage Products


EMC Atmos is a cloud storage services platform, Atmos can be deployed as either a hardware appliance or as software in a virtual environment. The Atmos technology uses an object storage architecture designed to manage petabytes of information and billions of objects across multiple geographic locations as a single system.

Atmos was organically developed by EMC Corporation and was made generally available in November 2008. A second major release in February 2010 added a "GeoProtect" distributed data protection feature, faster processors and denser hard drives.

During EMC World in May 2011, EMC announced the 2.0 version of Atmos with better performance, more efficient "GeoParity" data protection and expanded access with Windows client software (Atmos GeoDrive) and an Atmos SDK with Centera/XAM and Apple iOS compatibility.


Avamar is a used for backup the data and it uses the backup-to-disk technology. Backup-to-disk refers to technology that allows one to back-up large amounts of data to a disk storage unit. The backup-to-disk technology is often supplemented by tape drives for data archival or replication to another facility for disaster recovery. Additionally, backup-to-disk has several advantages over traditional tape backup for both technical and business reasons.

Another advantage that backup-to-disk offers is data de-duplication and compression. The disk appliances offer either de-duplication at the source or at the destination. The de-duplication at the destination is faster and requires less performance overhead on the source host. The de-duplication requires less disk space on the disk appliance as it stores only one copy of the possible multiple copies of one file on the network.


Content-addressable storage, also referred to as associative storage or abbreviated CAS, is a mechanism for storing information that can be retrieved based on its content, not its storage location. It is typically used for high-speed storage and retrieval of fixed content, such as documents stored for compliance with government regulations.

Content-addressed vs. location-addressed

When being contrasted with content-addressed storage, a typical local or networked storage device is referred to as location-addressed. In a location-addressed storage device, each element of data is stored onto the physical medium, and its location recorded for later use. The storage device often keeps a list, or directory, of these locations. When a future request is made for a particular item, the request includes only the location (for example, path and file names) of the data. The storage device can then use this information to locate the data on the physical medium, and retrieve it. When new information is written into a location-addressed device, it is simply stored in some available free space, without regard to its content. The information at a given location can usually be altered or completely overwritten without any special action on the part of the storage device.

when information is stored into a CAS system, the system will record a content address, which is an identifier uniquely and permanently linked to the information content itself. A request to retrieve information from a CAS system must provide the content identifier, from which the system can determine the physical location of the data and retrieve it. Because the identifiers are based on content, any change to a data element will necessarily change its content address. In nearly all cases, a CAS device will not permit editing information once it has been stored. Whether it can be deleted is often controlled by a policy.


Clariion is discontinued SAN disk array manufactured and sold by EMC Corporation, it occupied the entry-level and mid-range of EMC's SAN disk array products. In 2011, EMC introduced the EMC VNX Series, designed to replace both the Clariion and Celerra products. 

Upon launch in 2008, the latest generation CX4 series storage arrays supported fibre channel and iSCSI front end bus connectivity. The fibre channel back end bus offered 4 Gbit/s of bandwidth with FC-SCSI disks or SATAII disks.
The EMC Celerra NAS device is based on the same X-blade architecture as the CLARiiON storage processor.

In 2011, EMC introduced the new VNX series of unified storage disk arrays intended to replace both CLARiiON and Celerra products. Internally the VNX is labeled the CX5. In early 2012, both CLARiiON and Celerra were discontinued.


CloudBoost technology enables EMC NetWorker and Avamar users to reduce CapEx and eliminate tape in their environments by using a private, public, or hybrid cloud for long-term retention. Specifically, NetWorker with CloudBoost and Avamar with CloudBoost enable long-term retention of monthly and yearly backups to the cloud.

Data Domain:

Data Domain Corporation was an Information Technology company from 2001-2009 specializing in target-based deduplication solutions for disk based backup. Since its acquisition by EMC Corporation in 2009.

Data Domain was founded by Kai Li, Ben Zhu, and Brian Biles. The goal of the company was to minimize the tape automation market with a disk-based substitute. It did this by inventing a very fast implementation of lossless data compression, optimized for streaming workloads, which compares incoming large data segments against all others stored in its multi-TB store. Originally categorized as "capacity optimization" by industry analysts, it later became more widely known as inline "data deduplication".

It improve recovery confidence and ensure service levels with EMC’s powerful data protection management software. With Data Protection Advisor, you’ll be able to unify and automate monitoring, analysis and reporting across backup and recovery environments while reducing complexity, lowering costs, and eliminating manual efforts.


Greenplum was a big data analytics company headquartered in San MateoCalifornia. Greenplum was acquired by EMC Corporation in July 2010.

Greenplum, the company, was founded in September 2003 by Scott Yara and Luke Lonergan.

In July 2006 a partnership with Sun Microsystems was announced. Sun Microsystems was a reference architecture and used by the majority of Greenplum's customers to run its database until a transition was made to Linux in the 2009 timeframe. Greenplum was acquired by EMC Corporation in July 2010 becoming the foundation of EMC's Big Data Division. 


Isilon is a scale out network-attached storage platform offered by EMC Corporation for high-volume storage, backup and archiving of unstructured data. It provides a cluster-based storage array based on industry standard hardware, and is scalable to 50 petabytes in a single filesystem using OneFS file system.

An Isilon clustered storage system is composed of three or more nodes. Each node is a self-contained, rack-mountable device that contains industry standard hardware, including disk drives, CPU, memory and network interfaces, and is integrated with proprietary operating system software called OneFS, which unifies a cluster of nodes into a single shared resource.

Isilon Systems was a computer hardware and software company founded in 2001 by Sujal Patel. Isilon Systems was acquired by EMC Corporation in November 2010 for $2.25 billion.

EMC ScaleIO is a software-defined storage product from EMC Corporation that creates a server-based storage area network (SAN) from local application server storage, converting direct-attached storage into shared block storage. It uses existing host-based internal storage to create a scalable, high-performance, low-cost server SAN. EMC promotes its ScaleIO server storage-area network software as a way to converge computing resources and commodity storage into a “single-layer architecture".


In computing, Storage Resource Management (SRM) involves optimizing the efficiency and speed with which a storage area network (SAN) utilizes available drive space.Data growth averages around 50% to 100% per year Organisations face rising hardware-costs and the increased costs of managing their storage. Storage professionals who face out-of-control data-growth are looking at SRM to help them navigate the storage environment. SRM identifies underutilized capacity, identifies old or non-critical data that could be moved to less-expensive storage, and helps predict future capacity requirements.


Symmetrix arrays, EMC's flagship product at that time, began shipping in 1990 as a storage array connected to an IBM mainframe via the block multiplexer channel . Newer generations of Symmetrix brought additional host connection protocols which include ESCONSCSIFibre Channel-based storage area network. The Symmetrix product was initially popular within the airline industry and with companies that were willing to deviate from the safety of IBM's 3390 disk subsystem and take a risk with the unproven Symmetrix array. This product is the main reason for the rapid growth of EMC in the 1990s, both in size and value, from a company valued hundreds of millions of dollars to a multi-billion company.
