Kalray MPPA® DPU (Data Processing Units) Processors at the Heart of the Storage Revolution

The MPPA® DPU (Data Processing Unit) processor is at the heart of Kalray’s K200-LP™ NVMe-oF target controller and NVMe smart storage cards, bringing exceptional performances and capabilities. With Kalray DPU acceleration cards, get best performance per Watt and per Dollar on the market while differentiating with unique advanced custom features.

The Flashbox™ is a great example of how Kalray’s DPU smart storage cards can be leveraged to build unique storage solutions.

The latest generations of flash memory and NVMe SSDs offers unparalleled opportunities for data intensive applications such as AI, 5G, IoT, HPC … NVMe SSDs are up to 100 times faster than traditional SSDs, as NVMe protocol unlocks high IOPs, high bandwidth and ultra-low latency.

But NVMe adoption raises unique challenges: Existing solutions are unable to handle this massive performance leap. Kalray storage solutions, based on its unique Data Processing Unit, offer a unique way to unleash the full potential of NVMe SSDs.

Be part of the storage revolution with Kalray’s DPU acceleration cards!
