2 Special requirements of hosting on Memory Dedicated Servers Shared Services Storage / Caching Lowest power consumption during stand-by Highest affordable density with reasonable bandwidth Reliability, fast access, affordability 3 / 28 3 /? YYYY.MM.DD / 홍길동 책임 / xxxxxx팀

3 Challenges: Increasing power consumption Limited Power Budget Higher Carbon footprint = Higher Cost + Damaged Green image Increasing cost of energy 4 / 28 4 /? YYYY.MM.DD / 홍길동 책임 / xxxxxx팀

4 Challenges : Memory access time hits the performance wall , ,0 HDD , , ,0 SSD SSD = closing the storage gap 1.000,0 100,0 DRAM [ns] 10,0 1,0 0,1 CPU DRAM vs. CPU 0, [Carnegie Mellon Univ. & Samsung Estimation] 5 / 28 5 /? YYYY.MM.DD / 홍길동 책임 / xxxxxx팀

5 Challenges: between cost & performance CPU DRAM SSD HDD Faster access time Decreasing feasible density Increasing cost $/GB 6 / 28 6 /? YYYY.MM.DD / 홍길동 책임 / xxxxxx팀
