Identity & Definition
This enterprise Data Processing Unit (DPU), the NVIDIA BlueField-2 MBF2M355A-VECOT, is an E-Series DPU providing 200GbE single-port QSFP56 connectivity with PCIe Gen4 x16. This is a DPU (SmartNIC with programmable Arm cores and secure boot), not a standard NIC. This is the E-Series variant with Secure Boot and Crypto enabled. Condition: Refurbished — tested by T.E.S IT-SOLUTIONS.
Engineering Context
The BlueField-2 E-Series MBF2M355A-VECOT combines a ConnectX-6 Dx network adapter with an 8-core Arm A72 processor at 2.0 GHz and 32GB on-board DDR4 memory. The single QSFP56 port supports 200GbE Ethernet with RoCE v2 RDMA, VXLAN/Geneve offload, and inline IPsec/TLS encryption at line rate. PCIe Gen4 x16 provides 256 Gb/s host bus bandwidth. Secure Boot ensures firmware integrity validation at startup. The E-Series variant includes an integrated BMC for out-of-band management via 1GbE OOB port.
Deployment & Use Cases
Cloud infrastructure DPU for offloading OVS, NVMe-oF, and security functions from host CPUs in VMware ESXi, KVM, or OpenStack environments. Zero-trust security architectures requiring hardware-enforced secure boot and inline encryption. AI/ML cluster networking with RDMA offload and GPUDirect support. Multi-tenant bare-metal environments requiring hardware-isolated network functions.

Compatibility & Hard Constraints
Ethernet Only: This is the Ethernet variant. It does not support InfiniBand. For VPI (Ethernet + InfiniBand), use BlueField-2 H-Series. PCIe Gen4 x16 Required: Physical x16 slot required for full bandwidth. PCIe 3.0 compatible at reduced bandwidth. Single-Port: For dual-port 200GbE, use MBF2M516A series. DOCA SDK Required: Arm-side offload applications (OVS, NVMe-oF, firewall) require NVIDIA DOCA. Standard NIC passthrough mode works without DOCA. Secure Boot: Firmware must be signed and validated. Custom unsigned firmware cannot be loaded. Predecessor: BlueField-1. Successor: BlueField-3 (ConnectX-7 based, 400GbE).
