Kioxia and Dell cram 10 PB into slim 2RU server

Kioxia and Dell have built a 9.8 petabyte all-flash storage server in a 2-rack-unit form factor by packing 40 of Kioxia’s 245.76 TB LC9 QLC SSDs into Dell’s AMD EPYC 9005-powered PowerEdge R7725xd server. The system, which supports up to five 400 Gbps network interfaces for fast data egress, can deliver up to 196 PB of storage per rack when populated with 20 units. Dell and Kioxia said the high-density server enables customers to scale AI infrastructure and data lakes while reducing physical footprint and total cost of ownership.

The system supports up to 5x 400 Gbps NICs so it can ship data out quickly. Arun Narayanan, SVP Compute and Networking at Dell, said: “The Dell PowerEdge R7725xd combined with Kioxia's high-capacity enterprise SSDs delivers the storage density and power efficiency our customers need to scale AI infrastructure without sacrificing performance." There could be 196 PB in a rack fitted with twenty of these severs. Neville Ichhaporia, SVP and GM of the SSD business unit at Kioxia America, said that, with these servers, “customers can deploy massive ingestion streams, scale data lakes effortlessly, and handle large backups in a fraction of the footprint, improving TCO to new levels.” Other developers of 256 TB-class SSDs include Micron 6600 ION https://www.blocksandfiles.com/flash/2026/05/05/microns-new-ssd-replaces-disk-for-fast-access-storage/5219265 , Sandisk UltraQLC SN670 https://www.blocksandfiles.com/ai-ml/2025/08/05/sandisk-unveils-256-tb-ssd-for-ai-workloads-shipping-in-2026/1589534 , SK Hynix AIN D https://www.blocksandfiles.com/ai-ml/2025/08/25/sk-hynix-plants-flag-in-ultra-high-cap-ssd-area/1598727 and its Solidigm https://www.blocksandfiles.com/ai-ml/2025/10/09/solidigm-sheds-light-on-ssd-roadmap/1593835 subsidiary. Scality tells us it’s working on supporting a future nearline-class SSD from Samsung, viewed as an HDD killer, with similar or even larger capacity and a roadmap out to a 1 PB drive.
