There’s been a lot of discussion about “disaggregated” servers, racks and datacenters since Facebook FB -0.03% and Intel INTC -1.53% promoted their vision for the phrase at the Open Compute Summit at the start of this year. Haven't we spent the last few decades disaggregating datacenter architecture? And if so, what does disaggregation mean now, is it something different? I’ll try to be succinct as possible, but if you want a very deep dive, you can find it here.

Intel Disaggregated Server Rack Prototype

Strictly speaking, to “disaggregate” means to divide an integrated whole thing (an “aggregate”) into its component parts.

In many respects, Calxeda, AMD and HP are “re-aggregating” computer architecture. They are packing compute, storage, and local network fabric into a more tightly-integrated rack-level architecture to optimize east-west data flow at a local level. Instead of carving datacenter architecture into its component pieces, they are throwing components into a blender for a more fine-grained approach to optimizing hardware for specific workloads.

We believe that Intel is building a silicon photonics enabled system architecture optimized for large address space in-memory databases and Big Data analytics.
