The following figure shows the different DD series appliance features and benefits:
Figure 3. DD series appliance features and benefits
- Typically, 30% more logical capacity per TB compared to previous Data Domain appliances
- Previous Data Domain appliances used lz as the default local compression algorithm
- DD6400/DD6900/DD9400/DD9900 use gzfast by default – typically delivering a 30% better compression ratio than lz. This allows the default configuration of the latest DD products to store more customer data on the same amount of physical DD capacity when compared to the previous generation of Data Domain appliances.
- 5% ~ 25% performance improvement, depending on workload on restore and NFS/CIFS/VTL ingest
- No performance regression for other workloads—pure DD Boost ingest, Garbage Collection (GC), and replication workloads
- Enabled by default on all supported models DD6400/DD6900/DD9400/DD9900
- DD series appliances: faster networking options
- Up to 10x the throughput of the previous generation
- More backup streams can be aggregated with fewer network connections
The following figure shows the DD series appliance models with faster networking options.
