Product Number : Y1T43 ,0Y1T43 ,CX653105ADescription : DELL Mellanox ConnectX®-6 Single Port VPI HDR100 QSFP AdapterCondition: used (✅ Pre-owned & Clean Pulls & Tested 100% Fully Working & buy with confidence✅) Qty: 1Dell Y1T43 Mellanox ConnectX‑6 VPI
The Dell Y1T43 is an OEM‑branded Mellanox ConnectX‑6 VPI single‑port network adapter, purpose‑built for Dell PowerEdge rack‑mount servers, targeting high‑performance computing, cloud virtualization, distributed storage and NVMe‑oF environments. VPI (Virtual Port Interface) design allows the same physical QSFP56 port to run either 100GbE Ethernet or HDR100 InfiniBand, offering fabric flexibility for mixed‑protocol data‑center deployments.
Host interface is PCIe 4.0 x16, backward‑compatible with PCIe 3.0, delivering full 100 Gbps offerirectional throughput with ultra‑low latency down to sub‑600 ns and message rates up to 215 million messages per second. Form‑factor is full‑height full‑length (FHHL), standard full‑height bracket pre‑installed.
Rich hardware offloads reduce host‑CPU overhead: RoCE v1 / RoCE v2 RDMA, SR‑IOV virtualization (up to 512 virtual functions), VXLAN / GENEVE tunnel offload, NVMe‑oF initiator‑target acceleration, T10‑DIF data‑integrity checksum, and AES‑XTS block‑level hardware encryption with FIPS support.
Multi‑rate auto‑negotiation supports: 100/50/40/25/10/1 Gbps Ethernet, alongside HDR100 / EDR / FDR InfiniBand modes, working with QSFP56 / QSFP28 optical transceivers and passive/active copper cables. Supported operating systems cover Linux, Windows and VMware ESXi. This Dell‑validated SKU is widely used for GPU compute servers, SAN‑over‑IP storage clusters and enterprise high‑speed uplink scenarios.
