Bring composable-infrastructure economics to enterprise datacenters — pool endpoints, reallocate on demand, consolidate multiple workloads on one shared fabric.
A PCIe Gen4 fabric backplane that lets your IT team pool GPUs, NVMe, NICs, and FPGAs — and reassign them across workloads without recabling.
For enterprise datacenters running a mix of workloads (AI, analytics, databases, virtualisation), composable PCIe eliminates the over-provisioning tax. Buy the endpoints once. Route them wherever demand is.
The block diagram lays out the composable Enterprise PCIe Infrastructure. Multiple host servers each carry a PCIe HBA that connects into a shared Gen4 switch fabric. Behind the fabric sits a pool of PCIe endpoints — NVMe, GPU, DPU, or custom accelerator cards — that any host can claim on demand. A control plane (running on the same or an adjacent management node) enforces zoning, hot-plug, and telemetry. Utilisation of expensive accelerators is driven up; hardware refresh cycles move from server-level to endpoint-level.
The connection diagram shows the DF-S07 wired into an enterprise rack. Each participating host runs an MCIO cable to the switch chassis. External endpoints (JBOF, GPU box, DPU shelf) uplink to the same chassis. A dedicated management network reaches the control plane for zoning changes. A+B power feeds keep the fabric hot during PDU maintenance. Use this diagram to plan host-to-fabric cable topology, HBA placement, and control-plane network segmentation.

Enterprise IT lives with a hard trade-off: over-provision every server for worst-case workloads and waste hardware, or under-provision and hit performance ceilings during bursts. Composable PCIe removes the trade-off.
The Datafabrix Enterprise PCIe Infrastructure solution places a Gen4 fabric backplane at rack scale. GPUs, NVMe drives, high-speed NICs, and FPGAs live in a shared pool. Servers connect via cabled PCIe upstream lanes. Software policy binds endpoints to hosts as workloads demand.
The result: buy fewer GPUs, get more useful work out of them. Buy fewer NVMe drives, use them harder. Buy fewer NICs, saturate them under bursty workloads.
Cut hardware spend by 30–50% via shared endpoint pools.
Reassign hardware to whichever workload needs it now.
Give teams elastic access to a shared hardware pool.
