en.Wedoany.com Reported - KIOXIA America, Inc. and Dell Technologies jointly announced on May 14 a 2U rack server based on the Dell PowerEdge R7725xd platform. By integrating 40 Kioxia LC9 series 245.76TB NVMe SSDs, the server achieves 9.8PB of flash storage capacity within a single 2U chassis. This marks the industry's first achievement of this storage density level in a 2U form factor. The two companies position this configuration as a next-generation storage-optimized platform designed for AI workloads, large-scale data lakes, and data-intensive applications.
The Dell PowerEdge R7725xd is a storage-intensive server equipped with two 5th Gen AMD EPYC 9005 series processors, each featuring up to 192 cores, and 24 DDR5 DIMM slots. It utilizes an air-cooled thermal design, balancing performance with operational convenience. At the networking level, this model supports up to five 400Gbps network interface cards, providing high-bandwidth, low-latency transmission channels for large-scale AI model training and massive real-time data management. Designed around modern AI and data-intensive workloads, the PowerEdge R7725xd integrates high-density storage with computing power. Its air-cooled storage configuration can complement GPU servers, providing large-scale storage capacity support throughout the entire AI lifecycle.
For storage, the system utilizes the Kioxia LC9 series E3.L form factor 245.76TB NVMe SSDs. First announced in July 2025, this product features 32-layer stacked 2 terabit BiCS FLASH QLC 3D flash memory, combined with CMOS directly Bonded to Array (CBA) technology, achieving a 218-layer vertically stacked package. It is currently one of the highest-capacity volume production NVMe SSDs globally. The interface supports PCIe 5.0, with sequential read speeds up to 12,000 MB/s and random read performance of 1.3 million IOPS. The product is also compatible with NVMe 2.0, NVMe-MI 1.2c specifications, and the Open Compute Project Datacenter NVMe SSD specification v2.5. It supports Flexible Data Placement to reduce write amplification and extend SSD lifespan, with security options including SIE, SED, and FIPS SED.
Equivalent comparison data further illustrates the density advantage of this configuration. According to Kioxia's official calculations, building an equivalent 9.8PB storage scale using the currently common 30.72TB high-capacity SSDs would require approximately 280 additional drives and the deployment of over 7 servers. The overall power consumption would be 8 times that of the current solution, while rack space occupancy would also increase significantly. Arun Narayanan, Senior Vice President of Computing and Networking at Dell Technologies, stated that as AI workloads become increasingly demanding, the supporting infrastructure must evolve in tandem. The combination of the Dell PowerEdge R7725xd and Kioxia high-capacity enterprise SSDs provides customers with the storage density and energy efficiency needed to scale AI infrastructure without sacrificing performance.
In terms of deployment scenarios, the 9.8PB flash capacity in a single machine enables customers to deploy large-scale data ingestion streams, seamlessly scale data lakes, and handle large backup tasks within a minimal physical footprint. Neville Ichhaporia, Senior Vice President and General Manager of the SSD business unit at KIOXIA America, Inc., noted that the Kioxia LC9 series 245TB QLC SSDs represent not just higher density, but a shift in the approach to architecting AI infrastructure. By accommodating 40 drives in the Dell PowerEdge R7725xd server, a single 2U system achieves 9.8PB capacity, allowing customers to accomplish large-scale data ingestion, data lake expansion, and backup processing with a smaller footprint, elevating the total cost of ownership to a new level.
Dell and Kioxia have a long history of collaboration on scalable infrastructure for data-driven applications. This launch continues their shared technical roadmap of advancing high-density architectures, improving performance, reducing energy consumption, and enhancing data center efficiency. Specific pricing for this solution has not yet been announced. As it utilizes all top-tier enterprise core components and is custom-delivered for hyperscale data center customers, the overall procurement cost is positioned in the upper range of the industry.
