Dell EMC telemetry data shows that customers with Data Domain appliances that move to DD series appliances with hardware assisted compression using gzfast will experience higher compression ratios as compared to the previous generations of Data Domain that used the lz compression method. The data shows that the local compression ratio will improve by an average of 30% per TB for non-database workloads and 31% and 26% for MS SQL and Oracle workloads, respectively. These figures apply only to workloads are not already pre-compressed or encrypted.
