    Universe of Data growth vs. IT budgets: Growth by 2020-14X Enterprise data, 10X Servers, vs. 1.5X IT professionals, Memcached accounts for 10-30% of servers. Intel CPU Trends: Transistors, Clock speed, Power, Performance. Scoring Memcached: Factors to consider-Volume: Yes, 10-30% of servers 10X server growth by 2020, Low complexity, narrow focus: Yes, Stable design: Yes, Needs lower latency: Yes, Needs better throughput: Yes, but seems achievable with multiple cores as well as HW approach, Power efficiency matters: Yes, for all objects sizes 90 – 95% power reduction. Conclusions Memcached HW Acceleration: Favorable factors for the FPGA approach-7K queries / Watt vs. 100-200 queries / Watt, Significantly better max latency and distribution. Some Caveats: Similar throughput looks achievable without HW Acceleration-Could 64 cores yield 12 million TPS? Need to put this in context with power measurement for TPS per Watt; The FPGA results are experimental vs. the x86 results which included a more comprehensive feature set including exception handling and support for larger numbers of TCP sessions.
