11 Conseils Intégration systèmes Gestion infrastructure 11/29 XtremIO Inline Data Deduplication Lowers Effective Cost While Increasing Performance & Reliability Always on, inherent function Scales-out Truly inline, global, always on Improves array performance Lowers $/GB Extends flash endurance

12 Conseils Intégration systèmes Gestion infrastructure 12/29 XtremIO Inline Data - Compression Lower effective costs, increase usable capacity Always on, inherent function Compress unique data blocks after De-Duplication and before written to SSD Lower $/GB - more usable capacity Less CPU-Overhead Increase flash endurance

13 Conseils Intégration systèmes Gestion infrastructure 13/29 Total Data Reduction - Example 12 logical data blocks are written from the host 8 redundant blocks will be reduced by the Inline Deduplication so that 4 unique blocks stay over. Dedup = 3:1 4 unique blocks will be reduced by Inline Compression so that 2 phys. Blocks stay over. Compression = 2:1 Total data reduction of 12 logigal blocks to 2 phys. blocks = 6:1
