This is a curious piece of news: Server DRAM is going up, up, up in price, and it is because giant tech companies are buying all of it. The culprit is hyperscale data centers, which are larger than a football field according to Andy Patrizio in an article for Network World. “Hyperscale” means a minimum of 5,000 servers across 10,000 square feet. This is the natural consequence of the IT-as-a-service philosophy, and $547 billion will have been spent on related technology and services by the end of 2018.
However, Patrizio adds this:
One bright spot in the predictions is that production of 2133MHz products, the standard memory speed for server DIMMs, will be overtaken by memory with a higher clock rate (2666MHz and 2400MHz), so higher bandwidth server modules will become the mainstream products.
