Despite the trend swinging toward integrated data protection appliances, Dell EMC today expanded the line of Data Domain appliances that helped make disk-based backup popular.
Dell EMC launched the DD3300 appliance, the new entry-level version of its platform that does inline deduplication for disk backup, archiving and disaster recovery. The Data Domain appliance targets small to midsize organizations and large companies with remote and branch offices. The new system will replace the Dell EMC Data Domain 2200.
The DD3300 provides a maximum throughput of up to 4.2 TB per hour and 7 TB per hour with the Data Domain Boost technology. The Data Domain appliance can hold between 200 TB and 1.6 PB of logical capacity and up to 32 TB of usable capacity. Those numbers compare to the DD2200 appliance that protects up to 860 TB of user data and supports 4.7 TB an hour throughput.
The 2U appliance also has the DD Cloud Tier technology that does native tiering of long-term retention data to the public, private and hybrid cloud. With cloud tiering, the system can handle up to 4.8 PB of logical capacity and up to 32 TB of usable storage. It uses SAS drives and the system uses intelligent, variable-level deduplication.
"This enables smaller IT environments to extend to the cloud for long-term data retention," said Richa Dhanda, Dell EMC's director of product marketing for data protection. "The cloud tiering is offered on all our models, [but] this is the first time we are offering cloud tiering on our entry-level model."
Data Domain appliance gives deduplication a boost
The new Data Domain appliance supports dual-disk parity RAID 6, Data Domain encryption, Data Domain Extended Retention Lock software and Data Domain Virtual Tape Library over Fibre Channel. It supports NFS v3 over TCP and CIFS and Data Domain Boost over 1 GbE or 10 GbE or Fibre Channel, as well as NDMP Tape Server.
DD Boost software is designed to offload part of the Data Domain deduplication process to a backup server or application client. That prevents the Data Domain disk array from having to carry the full burden of the dedupe workload. The software is designed to increase the backup speed while decreasing the network bandwidth needs. This is particularly advantageous when backups are being written to an off-site Data Domain system over a wide-area network.
The new Data Domain appliance supports Amazon Web Services, Microsoft Azure, the IBM Cloud and the Dell EMC Elastic Cloud Storage.
Data Domain was a data deduplication pioneer that helped popularize the move from tape to disk for backup. EMC acquired Data Domain for $2.1 billion in 2009, and the platform has helped EMC -- and now Dell EMC -- hold the disk backup market share lead for years, although its share is shrinking as integrated appliances start to take hold.
Dell EMC in 2017 launched the Data Domain Integrated Data Protection Appliance (IDPA) with Data Domain and other Dell EMC backup software integrated. The IDPA is more in line with integrated appliances from rivals Veritas, Commvault and newcomers Cohesity and Rubrik, while the standard Data Domain appliance requires customers to use separate backup software. But despite the move into integrated appliances, the traditional DD appliances remain Dell EMC's flagship backup target products.
Along with the new DD3300, the Data Domain platform includes the midsize DD6300 and DD6800, and the DD9300 and DD9800 for large enterprises.
