The AI answer we saw
ARM-based DPUs suited for disaggregated storage include NVIDIA BlueField-3 (Arm Cortex-A78 cores with ConnectX-7 networking), Marvell OCTEON 10 (Arm Neoverse N2 cores), and Fungible DPU (now integrated into Microsoft's infrastructure). These devices offload storage protocols such as NVMe-oF, iSCSI, and erasure coding from host CPUs, enabling true disaggregation. Key evaluation factors include PCIe interface generation (Gen5 preferred), onboard DRAM capacity, supported storage protocols, and software ecosystem maturity (SPDK, DPDK compatibility). NVIDIA BlueField-3 currently has the broadest software ecosystem and partner support. Assess total cost of ownership including licensing for management software stacks.
