CDI Cluster

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, 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.
