A Reconfigurable Enterprise-grade AI/HPC Solution With Bare Metal Performance

Are you managing compute resources in a multi-tenant environment? Do you have some systems going unused while another type of system is always unable to meet user demand? Have you found your cloud environment to have unsustainably high operational costs? If so, consider the benefits of our CDI Cluster.

This Linux-based reference architecture provides a strong foundation for disaggregated environments, using industry leading technologies and optimized infrastructure design to ensure performance and flexibility. By leveraging PCIe-based fabrics and an innovative software layer, the CDI Cluster provides cloud-like flexibility with bare-metal performance, drastically improving ROI.

Also, by disaggregating resources from their physical configuration, the CDI Cluster improve the longevity of the underlying hardware investment. By easily reprovisioning these resources via software, you can redeploy resources in optimized configurations for a variety of workloads.

What Is CDI?

Composable disaggregated infrastructure (CDI) leverages PCIe-based low latency interconnects to enable dynamically provisioned systems. This lets system administrators pool resources like CPUs, accelerators (GPUs, FPGAs, ASICs), memory or storage without physical reconfiguration. Similarly, resources can be expanded, reduced, or refreshed on the fly.

Dynamically Provision Systems

By disassociating components from their physical location in a server within a cluster, unique hardware platforms can be spun up through software alone. This means users can optimally leverage available resources instead of relying on whatever node architecture is available.

Scale Resources as Needed

The CDI Cluster lets IT managers and system administrators change the way they think of resource procurement. By disaggregating hardware, CDI clusters can grow in whatever way your team needs, without unnecessary extra costs. For instance, an existing CPU-only CDI Clusters can be augmented to include GPU-acceleration using expansion chassis’ for PCIe-based GPUs. These chassis’, like JBODs, run without additional CPUs or storage devices.

Cloud-like Flexibility with Local Performance

Since CDI technology does not virtualize systems, there is no performance loss on the cluster when compared to a similarly equipped traditional HPC or AI cluster. Meanwhile, the software-managed, dynamically composable nodes maintain the ‘on-demand’ nature of the cloud many users have grown accustomed to.
