High speed datacentre backups

“EMC has far exceeded the inline deduplication performance benchmark it set with its previous top-of-line Data Domain system, but more importantly, the company has given customers a way to protect more of their data in a shorter period of time,” said Brian Babineau, Senior Consulting Analyst with Enterprise Strategy Group.


 “We expect more companies to evaluate integration between backup software and deduplication storage to maximise these performance levels and data reduction results while consolidating administrative tasks.” 


The Global Deduplication Array provides up to 14.2 petabytes (PB) of logical backup capacity, driving new levels of simplicity for data centre backup consolidation across workloads as diverse as very large databases, VMware images, and unstructured data. 


“While very sophisticated under the hood, it builds on the mature foundation of the existing Data Domain platform and retains its appliance simplicity,” said Brian Biles, Vice President of Product Management, EMC Backup Recovery Systems Division


“Its deduplication is inline; it’s blistering fast; and it’s big enough for significant datacentre backup consolidation. But its dynamic load balancing, single deduplication storage pool and namespace and tight integration with backup software means the Global Deduplication Array is easier to operate than competitors who don’t have its scale. EMC has once again moved the dial on disk-based data protection,” he added.


Capacity doubled

EMC also announced that its flagship single controller system for large enterprises, the EMC Data Domain DD880, now doubles its maximum capacity, offering support for up to 7.1 petabytes of logical backup storage and introduced EMC Data Domain Encryption software, the industry’s first data at rest encryption solution for deduplication storage systems designed to protect enterprise data in the event of theft or loss of disks and systems. 


Unlike most multi-controller deduplication systems, the inline Global Deduplication Array is tightly coupled with backup software, enabling industry leading inline deduplication performance, dynamic distribution of load and simplicity of operation.

The array distributes parts of the deduplication process to the backup servers to reduce network load and increase the throughput performance of the GDA controllers. It offers more than 3x faster backup throughput per controller than competitive deduplication configurations and is the fastest inline deduplication system available. 


 It presents a single inline deduplication storage pool to the backup application across two EMC Data Domain DD880 controllers. Large datacentre backup jobs are dynamically and transparently load balanced across the controllers, simplifying capacity management, performance management and backup administration.  


Features & benefits

·       For backup environments with hundreds of terabytes to process, administrators can target their backup policies to a Global Deduplication Array and leverage a common deduplication storage environment for all data protected by those policies. 

·       The Global Deduplication Array accommodates up to 270 concurrent backup jobs and up to 12.8 TB/hour of throughout allowing more backups to finish sooner while putting less pressure on limited backup windows. 

·       Global namespace minimises the need to reconfigure complex backup policies, while innovative global deduplication technology dynamically load balances policies for performance and capacity management.  Consequently, very large data sets can be easily protected with administrative simplicity while maximising overall deduplication efficiency and therefore minimising physical storage footprint.

 ·       With the EMC Data Domain Replicator software option, the Global Deduplication Array can automate wide area network (WAN) vaulting for use in disaster recovery (DR), remote office backup, or multi-site tape consolidation.

·       A single Global Deduplication Array can support a replication fan-in of up to 270 remote offices using smaller deduplication storage systems such as the Data Domain DD140 or the DD600 series appliances.

·       Cross-site deduplication further minimises the required bandwidth since only the first instance of data is transferred across any of the WAN segments between sites.  Additionally, for fast offsite protection and consolidation of tape out operations, the Global Deduplication Array provides up to 54 TB/hour of replication throughput.


EMC?s Data Domain Global Deduplication Array (GDA) is said to be the industry?s fastest inline deduplication storage system for enterprise backup applications solving the problem of how to get increasing amounts of backups done in the available time.
