First up Steve Kleiman from Network Appliance spoke about their intent to move flash into the clients that access NAS, so that it can intelligently cache and interact with the backend storage: Netapp is building host-side caches for VMware and HyperV The cache will be a block based read cache Cache is write through Andy Bechtolshiem, cofounder of Sun and now at Arista Networks talked about trends affecting system design and how Flash could be leveraged. 3d chip packaging will become common, to solve power and latency fundamentals around higher clock rate memory systems. This will mean that systems will become very NUMA, since the memory is directly attached to the cpu core. This is the decade where we switch to optical in the datacenter. Cutover is 10gbit (copper), 20 requires optical and will move to volume commodity ...
