Kalray, Vates and Scaleway alliance

News Jul 12, 2021

Vates, Kalray and Scaleway announce a partnership between the three companies to offer innovative solutions dedicated to the datacenter and beyond. The original announcement is available here.

Data Processing Units

DPUs are the future of the Datacenter and even beyond. After the CPU and the GPU, this new future pillar of your IT infrastructure will offload processing from your main CPU for all your heavily parallel tasks (storage, network or even AI/inference). Combine it with your virtualization platform, and you get the best of both worlds: virtualization flexibility while keeping bare-metal performance!

If you want to know more about it, watch our CEO's video on DPUs during the last Xen Summit:

K200‐LP + XCP-ng = 🚀

Working together with Kalray, our goal is to offer even more performance for your datacenter by making the Kalray K200-LP fully integrated inside XCP-ng. This will allow you to unleash bare-metal performance while keeping the flexibility of virtualization.

The XCP-ng team has currently started initial tests on the card, you can expect results soon with benchmarks on the XCP-ng blog.

Thanks to the partnership with Kalray and Scaleway, all teams can now work together to build a product opening new horizons in the virtualization world!
