Why Storage Class Memory means the end of traditional Storage Networking. DRAM ≈ 20ns latency Assume 50ns SCM access time (DRAM speed) PCIe, InfiniBand latency ≈ 1 μsec = 21x latency Speed of light in optical fiber ≈ .65 ft / nsec

+
5’ server rack
5 ft = 15nsec = 1.75x penalty
10 ft = 30nsec = 2.5x penalty
+ 40 ft = 120nsec = 6x penalty
