The ultimate protection storage appliance

DD series enables organizations to protect, manage and recover data at scale across their diverse environments. DD series is the next generation of Dell EMC Data Domain appliances, that are now setting the bar for data protection f rom edge to core to cloud. DD series provides the ecosystem support, efficiency, powerful data protection and cloud-enabled capabilities that customers have come to expect and appreciate from Data Domain.

The DD Operating System (DDOS) is the intelligence that powers DD series. It provides the agility, security and reliability that enables DD series to deliver high-speed, scalable and industry-leading multi-cloud protection storage for backup, archive and disaster recovery. DDOS integrates seamlessly with existing infastructure, enabling ease-of-use with leading backup and archiving applications, and offers superior performance in conjunction with Dell EMC PowerProtect Data Manager and Data Protection Suite.

Fast, secure and efficient data protection

DD series minimizes the risk of data loss and leverages the value of protected data, while meeting ever more demanding SLAs and increasing ROI. DDOS drives DD series to deliver up to 38% faster backups and up to 45% faster restores at higher compression levels. This improved level of compression efficiency increases the logical capacity by up to 30% per TB*.

DD series can now scale up to a physical capacity of 1.5PB in a single rack, thereby utilizing minimal floor space and lowering power and cooling by up to 41%. By employing denser disk drives, DD series has lowered the required rack space by up to 39%.

DD series provides up to an additional 2PB of Cloud capacity for long-term retention, with Dell EMC Cloud Tier. DD series supports high availability within the single rack. By doing so, DD series can further reduce the total cost of ownership by reducing downtime in the unlikely event of a hardware failure. DD series delivers high speed networking connectivity with support for 25GbE and 100GbE network adapters.

Instant access and instant restore

Instant access and instant restore delivers high performance of VMs with up to 60,000 IOPS with the ability to instantly access up to 64 VMs simultaneously.

Instant access and instant recovery save time, minimizing mean time to repair (MTTR), by enabling instant access to data f rom the backup image on the included DD series SSD drives. It also saves primary storage space with the ability to manage data on the appliance itself and lowers cost by better utilizing the physical resources in both the data protection as well as the production environments. In case of a failure or disaster recovery in a virtualized environment, DD series can spin-up production-oriented VMs immediately within the appliance itself . By doing so, the customer can continue their daily routine without experiencing any downtime, while the failed VMs are restored to the production environment.

Data Invulnerability Architecture

DD series is designed as the storage of last resort – providing you with the confidence that you can always reliably recover your data.

The Data Invulnerability Architecture is built into DDOS and DD series to provide the industry’s best defence against data loss. Inline write and read verification protects against and automatically recovers f rom data integrity issues during data ingest and retrieval while RAID-6 and hot spares protect against disk failure. Capturing and correcting I/O errors inline during the backup process eliminates the need to repeat backup jobs, ensuring backups complete on time and satisfy service-level agreements. In addition, unlike other enterprise arrays or file systems, continuous fault detection and self -healing ensures data remains recoverable throughout its lifecycle on DD series.

End-to-end data verification

End-to-end data verifications reads data after it is written and compares it to what was sent to disk, proving that it is reachable through the file system to disk and that the data is not corrupted. Specifically, when DDOS receives a write request from backup software, it computes a checksum over the data. After analysing the data for redundancy, it stores the new data segments and all the checksums. After all the data is written to disk, DDOS verifies that it can read the entire file from the disk platter and through PowerProtect DD, and that the checksums of the data read back match the checksums of the written data. This confirms the data is correct and recoverable from every level of the system.
