Differentiating between the Dell EMC Data Domain and ExaGrid EX Systems

(This blog was originally published by DCIG on January 25, 2018.)

Deduplication backup target appliances remain a critical component of the data protectioninfrastructure for many enterprises. While storing protected data in the cloud may be fine for very small businesses or even as a final resting place for enterprise data, deduplication backup target appliances continue to function as their primary backup target and primary source for recovering data. It is for these reasons that enterprises frequently turn to deduplication backup target appliances from Dell EMC and ExaGrid to meet these specific needs that are covered in recent DCIG Pocket Analyst Report.

The Dell EMC Data Domain and ExaGrid families of deduplication backup target appliances appear on the short lists for many enterprises. While both these providers offer systems for small, midsize, and large organizations, the underlying architecture and features on the systems from these two providers make them better suited for specific use cases.

Their respective data center efficiency, deduplication, networking, recoverability, replication, and scalability features (to include recently announced enhancements) provide insight into the best use cases for the systems from these two vendors.

Purpose-built, deduplication systems from both Dell EMC Data Domain and ExaGrid have widespread appeal as they expedite backups, increase backup and recovery success rates, and simplify existing backup environments. They offer appliances in vari­ous physical configurations to meet the specific backup needs of small, midsize, and large enterprises while provid­ing virtual appliances that can run in private clouds, public clouds, or virtualized remote and branch offices.

Their systems significantly reduce backup data stores and offer concurrent backup and replication. They also limit the number of backup streams, display real-time dedu­plication ratios, and do capacity analysis and trending. Despite the similarities that the systems from these respective vendors share, six differences exist between them in their underlying features that impact their ability to deliver on key end-user expectations. These include:

  1. Data center efficiency to include how much power they use and the size of their data center footprint.
  2. Data reduction to include what deduplication options they offer and how they deliver them.
  3. Networking protocols to include connectivity for NAS and SAN environments.
  4. Recoverability to include how quickly, how easily, and where recoveries may be performed.
  5. Replication to include copying data offsite as well as protecting data in remote and branch offices.
  6. Scalability to include total amount of capacity as well as ease and simplicity of scaling.
