Peace of mind. IBM understands that real solutions include more than  simply great engineering. Separately, the Data Reduction Guarantee, Controller Upgrade Program, and  High-Availability Guarantee each offer many benefits. But, when combined as part of an IBM  all-flash storage solution, the power of all three to help customers lower costs, reduce  business risk, and maintain the most current technologies can be even more significant; for  example, Flash endurance coverage while hardware maintenance is current ensuring Flash  wear never becomes a problem. IBM Storage developed the following new programs that are anchored to all-flash IBM storage  offerings: This usage of IBM FlashCore technology results in up to 3.8x improvement in endurance with  a potential 45% reduction in write amplification. These features are possible because of the following IBM patented and world-class  innovations:  IBM FlashSystem 900 Model AE3 features unique patented designs to ensure maximum  availability, which includes IBM Variable Stripe RAID™, IBM Inline Hardware Data  Compression, IBM Engineered ECC (error correction code), IBM Optimized  Over-Provisioning, advanced wear leveling on IBM MicroLatency modules, Write Buffer  and Hardware Offload, and IBM Garbage Collection.
