EMC Data Domain Product Overview

EMC Data Domain Product Overview

What is data domain in backup?
Data Domain provides the capability to consolidate both backup and archive data on the same infrastructure allowing greater consolidation by eliminating silos of backup and archive storage and associated overhead.

Data Domain provides high-performing, reliable backup, archive and disaster recovery capabilities to organizations of all sizes

What is Dell EMC Data Domain?
Dell EMC Data Domain has a distinguished pedigree when it comes to data deduplication and storage. Before its acquisition by EMC, Data Domain Corporation was a longstanding leader in the data deduplication storage systems space and the primary innovator of disk-based substitutes for backup tapes. Now absorbed into the Dell EMC PowerProtect line of data protection solutions, Data Domain can now be found in the Dell EMC Data Domain line of appliances in several models: DD6300, DD6800, DD9300 and DD9800.

A key underlying component of Data Domain is the Data Domain Operating System (DD OS) and its Data Domain Stream-Informed Segment Layout (SISL) scaling architecture. DD OS is a core part of Dell EMC Data Domain's Data Invulnerability Architecture, a framework built into the product line for mitigating the risk of data integrity issues. SISL relies on CPU power and performance to continuously minimize the disk accesses required to deduplicate data—specifically, by identifying duplicate data segments in memory, thereby minimizing disk usage.

Benefits of Dell EMC Data Domain
As the industry's most battle-tested and cloud-enabled data storage and protection solution, Data Domain enables organizations to leverage scalable cloud protection storage—regardless of the composition of their IT environments. For on-premises, automated data deduplication and protection, Data Domain reduces network utilization for cost-efficient storage.

Inline data verification
A myriad of issues can occur that impact the integrity of data during ingestion and retrieval. Data Domain provides continuous fault detection and self-healing for ensuring that data is recoverable throughout its Data Domain lifecycle. By detecting and remediating input/output (I/O) errors during the backup process, Data Domain eliminates the need for repeat backup jobs and ensures that each job is completed on-time and in-line with SLA agreements. Along with inline write and read verification for protecting and recovering from data integrity issues, Data Domain also performs end-to-end verification to confirm that data is correct and recoverable at all system levels.

Ideal use cases
Data backup, archive and disaster recovery
Data Domain provides high-performing, reliable backup, archive and disaster recovery capabilities to organizations of all sizes. For example, the DD6300 appliance was designed for providing high-speed and variable-length deduplication and cost-effective data protection and storage to small and medium-sized data centers.

Data on disk is available online and onsite for longer retention periods and restores and retrievals become faster and more reliable. This efficiency enables Dell Data Domain to protect up to 50PB logical capacity on a single system, with the ability to natively-tier another 100PB of deduplicated data to the cloud for long-term retention with Data Domain Cloud Tier. As a result, months of retention on disk is possible using the same number of "floor tiles" that traditionally provided only a couple of days of disk staging.

Long-term cloud retention
Dell Data Domain offers native support and tiering to public, private and hybrid clouds, enabling organizations to implement simple and efficient long-term retention strategies—not to mention low-cost cloud-based disaster recovery mechanisms.

Additionally, support for secure multi-tenancy allows for the logical isolation of user data; in these scenarios, only unique data is sent from Data Domain to the cloud, with data arriving to cloud object storage already deduplicated. Supported cloud vendors include AWS, Microsoft Azure, Google Cloud Platform and Alibaba Cloud, to name a few.

Protection for physical, virtual and cloud environments
Large enterprises and organizations with a mix of on-premises, public cloud, hybrid cloud and virtual environments benefit from Dell Data Domain's support of secure multi-tenancy and data protection as a service. With secure multi-tenancy, tenant data and networks are logically isolated for strict data access isolation. Additionally, Data Domain Cloud DR (DD Cloud DR) allows for the copying of on-premises VM backups to the public cloud, as well as the orchestration of disaster recovery testing and failover of workloads to the cloud with end-to-end orchestration.
