EMC Data Domain
Scale and performance
Reduce storage required by 10–30x
Protect up to 100 PB of logical capacity in a single system
Complete backups faster—up to 31 TB per hour
Seamless integration
Reliable access and recovery
Efficient resource utilization
*
Data Domain systems are a protection storage platform for backup and archive data that reduce the amount of disk storage needed to retain and protect data by ratios of 10-30x and greater, making disk a cost-effective alternative to tape. These systems can protect up to 100 PB of logical capacity in a single system enabling customers to retain data online and onsite for longer retention periods, as well as providing faster and more reliable restores.
With throughput up to 31 TB/hour, Data Domain systems allow more backups to complete sooner while putting less pressure on limited backup windows.
EMC Data Domain Replicator software transfers only the deduplicated and compressed unique changes across any IP network, requiring a fraction of the bandwidth, time, and cost, compared to traditional replication methods. “Time-to-DR readiness” is greatly reduced when compared to other replication methods.
Data Domain’s Data Invulnerability Architecture – built into every Data Domain system – provides the industry’s best defense against data integrity issues ensuring you can access and recover your data when you need it.

Why Protection Storage?
Inline deduplication minimizes storage footprint by 10–30x
Data Domain Data Invulnerability Architecture ensures data is recoverable and accessible
Consolidate backup, archive, and disaster recovery on a single system
Protect a wide variety of data sources
*
When we talk about ‘protection storage’, it’s all about three key pillars: enabling scale without cost and complexity, ensuring your data is recoverable AND accessible, and consolidating a broad range of data protection use case.
Data Domain systems fulfills these pillars in the following ways:
Inline deduplication minimizes your storage footprint by 10 – 30x enabling scale without cost and complexity.
The Data Domain Data Invulnerability architecture built into every Data Domain system provides the industry’s best defense against data integrity issues ensuring your data is both recoverable and accessible when you need it.

Now let’s take a closer look at the Data Domain storage system itself moving from the outside in.
This is a picture of what you would see in a Data Domain deployment. A Data Domain appliance is a storage system with shelves of disks and a controller. It’s optimized, first to back up and second to archive applications, and supports the industry-leading backup, archiving and enterprise applications.
The list on the left is composed primarily of leading backup, archive, and enterprise applications—not only EMC’s offerings with EMC NetWorker & SourceOne, but also Symantec, CommVault, Oracle and so on…
On the way into the storage system, data can pass through either Ethernet or Fibre Channel. With Ethernet, it can use mass protocols and NFS or CIFS; it can also use optimized protocols or products, such as Data Domain Boost, a custom integration with leading backup applications. Fibre Channel connectivity enables a Data Domain system to act as a virtual tape library or you can use DD Boost over Fibre Channel to eliminate virtual tape management.

FRIDAY FULL 1 TB 2–4x 250 GB
Second Friday Full Backup
*
A technology overview of data deduplication will help illustrate how you can store more backups in a smaller footprint with Data Domain.
Note to Presenter: Click now in Slide Show mode for animation.
On Friday, the backup application initiates the first full backup of 1 TB, but only 250 GB is stored on Data Domain. This occurs because as the data stream is coming into Data Domain, the system is deduplicating before storing data to disk. On average this results in a two- to four-times reduction in data on a first full backup.
Over the course of the week, 50 GB daily incremental backups result in a seven- to 10-times reduction and only require 5 GB to be stored. As the graphic on the left shows, during the week incremental backups contain data that was already protected from the first full backup.
Finally, on the second Friday, the second full backup contains almost all redundant data. Therefore of the 1 TB backup dataset, only 18 GB needed to be stored.

Deduplication

Deduplication
*
One of the most conventional alternatives to the Data Domain inline deduplication storage system approach (shown on the left) is by using a methodology known as post-process (shown on the right). In the post-process architecture, data is stored to a disk before deduplication. Then after it is stored, it is read back internally, deduplicated, and written again to a different area.
Although this approach may sound appealing because it seems as if it would allow for faster backups and the use of less resources, it actually creates two problems:
First, a lot more disk is needed to store the multiple pools of data, and for speed, because most of the other vendor’s deduplication approaches are spindle-bound. Because of this, there’s typically a factor of three or four more disks in a post-process configuration than you’ll see in a Data Domain deployment.
*
CPU-Centric v Spindle-Bound Performance
*
This slide shows another way to look at the virtues of being CPU-centric.
As mentioned before, most of the deduplication competitors for backup targets are spindle-bound or disk-bound. It takes so many disk seeks to look up the information to tell whether data has been stored before or not, and to sort out and then minimize the data, that it takes a lot of disk drives or faster disk drives to get the job done.
This slide shows what’s happened in our competitive environment as a result. If they’re using SATA disk drives, most deduplication storage vendors tend to need three or four times as many drives as a Data Domain system to store the same amount of deduplicated data.
In some cases, for example, IBM’s ProtecTIER, storage systems use Fibre Channel drives instead of SATA. This can decrease the seek time, but it comes at a significantly higher cost. Data Domain systems, by being CPU-centric and minimizing disk usage to only what is required to store the actual data, end up having a smaller footprint. This can look like a weakness, but it’s actually a strength.

Let’s examine how Data Domain systems are the ideal protection storage platform for backup and archive data. On the top here, you can see a variety of data sources including databases, e-mail servers, virtual machines and more. On of the main strengths of Data Domain systems is that all of these data sources and a broad range of backup and archive use cases with leading backup and archive applications can be protected on a single system.
For both backup and archive use cases, one of the key differentiators Data Domain systems offer is the ability to encrypt data inline, meaning data is deduplicated then encrypted in real-time as it is written to disk. Furthermore, on the archive side, Data Domain systems can meet a variety of US and international compliance regulations for archive data – including SEC 17a-4(f).
