Are your enterprise servers new and genuine?

Yes. We supply new and factory-sealed new-old-stock (NOS) servers from Dell, Lenovo, xFusion and Inspur, sourced through authorized manufacturer channels. New servers are covered by a 3-year warranty.

Can you ship GPU and storage servers to my country?

We export to 60+ countries across North America, Europe, the Middle East, Southeast Asia, Africa and Latin America, with door-to-door freight, customs documentation and insurance handled by our team.

How fast will I receive a quotation?

Most configuration lists receive a detailed quotation within one business day. For complex deployments, our engineers confirm compatibility and provide options before pricing.

Do you support system integrators and resellers?

Yes — system integrators, IT resellers, project suppliers and tender bidders are our primary customers. We offer multi-brand consolidation, neutral configuration advice and repeat-order account support.

How do I pay, and what terms are available?

We accept international bank transfer (T/T) in USD. Standard orders are confirmed against a proforma invoice, while established repeat accounts and project bidders can discuss agreed payment terms in advance.

What is the lead time for delivery to the Middle East or Southeast Asia?

In-stock configurations are normally built and tested within a few business days, followed by door-to-door air or sea freight depending on the destination. We provide a clear timeline and tracking once the order is confirmed.

How is warranty and after-sales support handled overseas?

New servers carry a 3-year warranty. Our support team coordinates with the manufacturer and arranges replacement parts and remote troubleshooting, so you receive the same level of service in any region we ship to.

Can you build a fully custom configuration to my specification?

Yes. Send your required CPU, memory, drives, accelerators, power and networking preferences — or simply describe the workload and target budget. Our engineers specify, assemble and burn-in test the complete system before shipment.

Nvidia ConnectX-7 Network Adapter for xFusion Servers

This page groups the xFusion network adapters based on Nvidia ConnectX-7. They are offered in 200GbE / 400GbE speeds, with 1-port builds and OSFP interfaces. They are validated for FusionServer V5–V8 rack and high-density nodes.

At a glance

Controller: Nvidia ConnectX-7
Port speed: 200GbE / 400GbE
Ports: 1
Connectors: OSFP
Form factor: PCIe card
PCIe host: 3.0/4.0
RDMA / RoCE: Yes
InfiniBand: Yes

Overview

Controller silicon: Nvidia ConnectX-7. Host interface: PCIe 3.0/4.0.

Port speeds available: 200GbE / 400GbE, using OSFP connectors. 2-port and (where listed) 4-port cards are available.

The controller supports RDMA over Converged Ethernet (RoCE) for low-latency storage and HPC traffic, plus SR-IOV virtual functions for virtualized hosts.

Some variants also operate as InfiniBand HCAs (NDR/HDR/EDR), so they can be used in IB fabrics as well as Ethernet.

Cabling note: Optical modules/DAC are sold separately unless the variant states they are included.

How to choose

Choose the speed and connector to match your top-of-rack switch: copper DAC for short, low-cost links, fiber/AOC for longer runs, and RJ45/BASE-T where copper structured cabling already exists. Prefer OCP 3.0 on servers that route the NIC through the chassis to free PCIe slots.
