Seagate is celebrating the debut shipment of very sophisticated storage solutions to a preferred client (dealing in the cloud data center sector). These 30+ terabyte hard drives are based on heat-assisted magnetic recording (HAMR) technology - the American data storage company is setting up its next generation Corvault range with the thermal magnetic recording methodology. The first shipment of HAMR-based drives is reported to consist of final qualification samples, but Seagate is anticipating that fully verified equipment - after trial customers give this new product lineup a thumbs-up - will be generating revenue in the coming weeks.

According to a transcript of a recent Seagate financial meeting conference call, CEO Dave Mosley mentioned a dip in business as well as a costly legal settlement, but expects company fortunes to rise due to client uptake of breakthrough storage technologies: "Beyond this cycle, we remain excited about the long-term opportunities presented by the secular growth of data and the relevance of mass capacity storage as new data-centric applications emerge and more workloads migrate to the cloud. We continue to make strong progress on our industry-leading technology road map, including launching HAMR-based products this quarter, which we believe put us in outstanding longer-term position."

AMD and JEDEC are collaborating to create a new industry standard for DDR5 memory called MRDIMMs (multi-ranked buffered DIMMs). The constant need for bandwidth in server systems provides trouble that can not easily be solved. Adding more memory is difficult, as motherboards can only get so big. Incorporating on-package memory solutions like HBM is expensive and can only scale to a specific memory capacity. However, engineers of JEDEC, with the help of AMD, have come to make a new standard that will try and solve this challenge using the new MRDIMM technology. The concept of MRDIMM is, on paper, straightforward. It combines two DDR5 DIMMs on a single module to effectively double the bandwidth. Specifically, if you take two DDR5 DIMMs running at 4,400 MT/s and connect them to create a single DIMM, you get 8,800 MT/s speeds on a single module. To efficiently use it, a special data mux or buffer will effectively take two Double Data Rate (DDR) DIMMs and convert them into Quad Data Rate (QDR) DIMMs.

The design also allows simultaneous access to both ranks of memory, thanks to the added mux. First-generation MRDIMMs can produce speeds of up to 8,800 MT/s, while the second and third generations modules can go to 12,800 MT/s and 17,600 MT/s, respectively. We expect third-generation MRDIMMs after 2030, so the project is still far away. Additionally, Intel has a similar solution called Multiplexer Combined Ranks DIMM (MCRDIMM) which uses a similar approach. However, Intel's technology is expected to see the light of the day as early as 2024/2025 and beyond the generation of servers, with Granite Rapids likely representing a contender for this technology. SK Hynix already makes MCRDIMMs, and you can see the demonstration of the approach below.

All eyes - especially investors' eyes - are on Intel's data center business today. Intel's Sandra Rivera, Greg Lavender and Lisa Spelman hosted a webinar focused on the company's Data Center and Artificial Intelligence business unit. They offered a big update on Intel's latest market forecasts, hardware plans and the way Intel is empowering developers with software.

Executives dished out updates on Intel's data center business for investors. This included disclosures about future generations of Intel Xeon chips, progress updates on 4th Gen Intel Xeon Scalable processors (code-named Sapphire Rapids) and demos of Intel hardware tackling the competition, heavy AI workloads and more.
