Reduce data in real-time in storage system - Deduplication / Compression
The Deduplication/Compression function analyzes duplicated data in every 4KB of the write data from the server, and writes the duplicated data only once. After the first write, the data is referenced instead of writing the same data again. This reduces the total write size. Also, with the compression function further data reduction is realized.
For the deduplication function and the compression function, either one or both can be used.
Benefit
- Efficient utilization of drives
- Reduces total writes and extends the life of SSD
