SSD market momentum and drivers, Placement in server/storage applications, Application specific requirements and workload characteristics, Proof points with SSDs in transaction processing, IT, virtualization, Call to action. Strong SSD Momentum in the Market - Drivers Behind Data Center Storage - Architectural Changes –Big data, Cloud, Software innovation for caching, tiering, Server Side Innovations-De-duplication, compression, Thin-provisioning, Virtualization, Interface transitions, SATA/SAS to PCIe, AHCI based to NVMe, SSD endurance and performance grades, Endurance classes – high, medium, standard, Optimization for access – read intensive, write intensive, mixed workload, Different “out of the factory” spare area level. Highest Requirements for Data Center SSDs - Data Integrity, True End to End data protection, Power Loss Protection, Power loss cap self test, Protection of internal memory with ECC and parity. Predictable Performance, IOPS variation needs to be within a narrow range, Latency outliers should be within a max value. High Endurance Requirement, Two primary endurance evolving, Standard endurance 0.1-1 DWD, High endurance 10 DWD. Transaction Processing And Importance of Latency QoS. Transaction processing requires dense IO (Higher IOPS/GB), Systems tune to have no “storage bottleneck”, No Mercy for latency outliers and occasional drops of IOPS. SSDs for IT Management Services - Automatic Updates for IT security patches, Managing Design Simulation database, Swap operation for over-flow memory, Benchmarking and proof points.
