Identity: The 0M9NW6 is a Dell OEM dual-port 40GbE network interface card based on the NVIDIA Mellanox ConnectX-3 chipset, supplied with a short (low-profile) PCIe bracket for installation in Dell PowerEdge 1U rack servers and other low-profile PCIe slot environments. MPN: 0M9NW6. This product IS a standard PCIe add-in card with QSFP ports, supplied with low-profile bracket. It is NOT a mezzanine adapter, NOT a full-height card (short bracket only included — full-height bracket requires sourcing separately), and NOT the ConnectX-3 Pro variant (which supports RoCE v1). The 0M9NW6 is the ConnectX-3 Ethernet (EN) dual-port 40GbE variant without InfiniBand support. Condition: refurbished.
Engineering: The ConnectX-3 chipset delivers dual 40GbE ports via two QSFP connectors. The PCIe 3.0 x8 host interface provides up to 64 Gb/s of aggregate host bandwidth. SR-IOV is supported with up to 64 virtual functions (VFs) per port, enabling hypervisor bypass in VMware ESXi and Hyper-V deployments. The low-profile (short) bracket makes this adapter suitable for Dell PowerEdge 1U servers (R620, R320, R220 series and others) that accept LP PCIe cards. The 0M9NW6 Dell FRU number is Dell's OEM version of the standard NVIDIA Mellanox MCX314A-BCCT (ConnectX-3 EN dual-port 40GbE, PCIe 3.0 x8, short bracket).
Deployment: Deployed in Dell PowerEdge 1U rack servers requiring dual 40GbE connectivity where low-profile PCIe brackets are mandated by chassis depth, in VMware ESXi vSphere environments on Dell PowerEdge R-series 1U platforms with SR-IOV VF-per-VM assignment at 40GbE, in Hyper-V clusters running 40GbE uplinks for live migration and shared storage traffic, and in HPC environments where dual 40GbE per node is required within 1U rack form factor. Also suitable for non-Dell servers with low-profile PCIe 3.0 x8 slots.
Specifications:
MPN (Dell FRU): 0M9NW6
Chipset: NVIDIA Mellanox ConnectX-3 (EN)
OEM Branding: Dell (for Dell PowerEdge platforms)
Port Count: 2 (dual-port)
Port Speed: 40GbE per port
Connector: QSFP (per port)
PCIe Interface: PCIe 3.0 x8
Bracket: Short / Low-Profile (LP) — full-height bracket NOT included
SR-IOV: Yes (up to 64 VFs per port)
RDMA: Not supported (EN chipset, not ConnectX-3 Pro)
Condition: Refurbished
Compatibility: Compatible with Dell PowerEdge servers with low-profile PCIe 3.0 x8 slots, including R620, R320, R220, R430, and R530 series. Also compatible with any server having a low-profile PCIe 3.0 x8 slot. QSFP ports accept standard 40GbE QSFP DAC cables and active fiber cables. NOT compatible with full-height-only PCIe slots without sourcing a full-height bracket separately. NOT the ConnectX-3 Pro — this variant (EN) does NOT support RoCE or InfiniBand. For RoCE capability at 40GbE, the Dell OEM ConnectX-3 Pro (MCX314A-BCBT retail equivalent) is required. Predecessor: Dell OEM ConnectX-2 dual-port 10GbE. Successor: Dell OEM ConnectX-4 Lx (25GbE, RoCE v2).
