There are still 8-socket systems, like the Supermicro 7088B (192 DIMMs), which support a theoretical 24 TB (with 128 GB modules).
(It would be interesting to know whether this backplane-based system actually manages to achieve 4.8 GHz QPI speed (9.6 GHz symbol rate), or whether the physical aspects limit it to lower speeds. Given that processors only have four QPI links this would further increase communication overhead -- in a 8-way system some sockets are separated by two hops).
- chx 9y agoSo 128GB modules exist and available http://www.memory4less.com/crucial-128gb-ddr4-pc19200-m386aak40b40-cuc http://www.memory4less.com/crucial-128gb-ddr4-pc19200-m386aa... but at least 30% more expensive than 2*64GB: http://www.memory4less.com/samsung-64gb-ddr4-pc17000-m386a8k40bm1-cpb http://www.memory4less.com/samsung-64gb-ddr4-pc17000-m386a8k... and of course this is the cheapest vendor. Brand names will fleece http://www.memory4less.com/hp-128gb-ddr4-pc19200-809208-b21 http://www.memory4less.com/hp-128gb-ddr4-pc19200-809208-b21 you for 128GB modules while http://www.memory4less.com/hp-64gb-ddr4-pc17000-726724-b21 http://www.memory4less.com/hp-64gb-ddr4-pc17000-726724-b21 64GB is just a little more expensive.
