According to DRAMeXchange analyst Mark Liu, server DRAM modules are supporting higher data transfer bandwidths, from 2133MHz and 2400MHz to 2666MHz. In terms of capacity, the mainstream modules have also expanded to 32GB. “Going into the second half of 2017, the growth in the memory content per box for servers and the increase in the market penetration of 32GB product lines are expected to be the main demand drivers,” said Liu. DRAMeXchange projects that the penetration of 32G capacity option in the total server DRAM module shipments will surpass 60% by the end of 2017.

Looking at the server market, product orders during the second half of 2017 will be mostly related to the procurement contracts that were made in the year’s first half by data center operators, enterprises and government organizations. Furthermore, a sizable part of this demand will be for servers based on Intel’s Purley platform. The initial shipments of Purley-based servers are expected to mostly go to data centers that will be replacing outdated hardware. As for enterprise servers with Purley solutions, their market releases are mainly scheduled in the first quarter of 2018. The market penetration of high-capacity modules such as 32GB RDIMMs and 64GB LRDIMMs is expected to accelerate with the arrival of Intel’s new platform.

With regard to server DRAM supply, currently memory suppliers’ shipment fulfillment rates have been around 60% to 70% since the start of this year. The market therefore is still in undersupply. At the same time, procurement contracts made during this year’s first half together with the arrivals of Purley-bases servers will keep pushing up demand for server DRAM products – especially high-capacity modules – to the end of the year.

On the technology front, the majority share of the server DRAM production is still done using older generations of manufacturing processes. Transitioning to 10nm-class nodes has been a major challenge for the whole industry. Server DRAM suppliers therefore have been fairly cautious in their process migration to ensure product reliability, and volume production of server DRAM using 1x-nm nodes is expected to become mainstream later in 2018.

DRAMeXchange also estimates that global server shipments in the latter half of 2017 will grow by around 10% compared with the first half of the year. In terms of shipment market shares for 2017, the top three server vendors will still be HPE, Dell and Lenovo with a combined global market share of about 40%. Huawei has the highest estimated year-on-year shipment growth for 2017 at almost 30%. Sugon and Inspur are expected to share second place for shipment growth with year-on-year grow
