Designed primarily for data centers, cloud applications, and other high-bandwidth workloads, the NVIDIA Mellanox ConnectX-6 Lx Dual-Port 25G SFP28 Network Interface Card enhances your compatible HP server or workstation with fast and reliable fiber connectivity. Installing this network interface card into an available PCIe 4.0 x8 expansion slot provides two SFP28 slots, each of which supports up to 25 Gb/s speeds. A single port connection can reach up to 50 Gb/s.

NVIDIA Accelerated Switch and Packet Processing (ASAP2) technology provides accelerated performance by offloading the software-defined networking (SDN) data plane to the NIC. Full-height and low-profile brackets are included.

PCIe 4.0 x8 Host Connection    2 x 25G SFP28 Slots    Up to 25 Gb/s Throughput (Dual-Port)    Up to 50 Gb/s Throughput (Single-Port)    Includes Full & Low-Profile Brackets    ASAP2 Technology

NVIDIA Accelerated Switch and Packet Processing (ASAP2) technology offloads the software-defined networking (SDN) data plane to the NIC, accelerating performance and offloading the CPU in virtualized or containerized cloud data centers. Datacenters may be accelerated with a single-root input/output (IO) virtualization (SR-IOV) or VirtIO interface while continuing to enjoy their SDN solution of choice.

The ConnectX-6 Lx ASAP2 rich feature set accelerates public and on-premises enterprise clouds and boosts the transition of cloud service providers (CSPs) to network function virtualization (NFV). ASAP2 supports these CSPs by enabling packet encapsulations, such as multiprotocol label switching (MPLS) and GPRS Tunneling Protocol (GTP), alongside cloud encapsulations, such as Virtual Extensible LAN (VXLAN), Generic Network Virtualization Encapsulation (GENEVE), and others.

Providing remote direct-memory access (RDMA) over converged Ethernet (RoCE) capabilities, ConnectX-6 Lx enables more scalable, resilient, and easy-to-deploy RoCE solutions. With zero-touch RoCE (ZTR), the ConnectX-6 Lx allows RoCE payloads to run seamlessly on existing networks without special configuration, either to priority flow control (PFC) or explicit congestion notification (ECN), for simplified RoCE deployments. ConnectX-6 Lx ensures RoCE resilience and efficiency at scale.

ConnectX-6 Lx adapters offer advanced, built-in capabilities that bring security down to every node in the data center. Features include Internet Protocol Security (IPsec) inline encryption and decryption acceleration. ASAP2 connection-tracking hardware offload accelerates Layer 4 firewall performance. The ConnectX-6 Lx also delivers supply chain protection with hardware root of trust (RoT) for secure boot and firmware updates using RSA cryptography and cloning protection via a device-unique key, guaranteeing firmware authenticity.

Q: 1. Does it come with the mounting hardware to set it up firmly on the desk?

A: Yes it comes with all the necessary Hardware yes it comes with all the necessary Hardware I had someone install it but it was not a difficult installation probably could have done it myself and I think it's an excellent piece of equipment I would highly recommend it.

Q: 2. Will 28 size monitors fit on this?

A: Yes 2 28 monitors will fit, but anything larger will require a extension arm. I have a wide screen 34 side by side with a 27 using a pair of extension arms. These mounts are extremely sturdy. I'm very satisfied with my purchase.

Q: 3. Will this stream Ustream or Livestream and work with Sony Vegas?

A: No, as of right now this will only support Final Cut Pro 6.0.5 or higher on Mac OS Xand Adobe Premiere Pro 4.0.1 or higher on Windows 7 / Vista / XP.

Q: 4. Can I use this device to: 1) send analog out to ATEM Mic In. 2)USB to comp-1 streaming soft. 3) Dante to comp-2 running zoom?

A: Yes, the analog output from the Shure ANIUSB-MATRIX USB Audio Network Interface can be connected to the mic input on the Blackmagic Design ATEM Switcher (set the input level on the ATEM for line level audio signal). The USB port from the ANIUSB-MATRIX can be connected to a computer for streaming audio, and the Dante port on the ANIUSB-MATRIX can be connected to a network switch to receive Dante audio, Power over Ethernet (PoE), and data from the control software, then the second computer can be connected to the network switch to send and receive audio for the Zoom meeting.

Q: 5. Are you going to sell the Nvidia ConnectX-6 100g cards too?

A: Regarding the NVIDIA ConnectX-7 200GB/s NDR200 IB Single-Port OSFP Adapter Card (Secure Boot), currently, we do not sell the NVIDIA ConnectX-6 100g cards.

Q: 6. Is this compatible with Avid Media Composer?

A: Software Supported: Final Cut Pro 6.0.5 or higher on Mac OS X The HD Express driver installer with Avid support is now available for download. This updated software installer provides compatibility with (and is required for) the Media Composer 6.5 family of products. if you prefer to edit more conveniently at a lower data rate, you can choose Apple ProRes, ProRes HQ, Avid DNxHD, or the codec of your choice in Avid Media Composer 6.5 or Apple Final Cut Pro for maximum CPU efficiency and smooth editing. In Premiere Pro on Windows, you can choose among several popular codecs, including DVCProHD. By choosing a codec directly supported by your host, you eliminate unnecessary extra stages of compression and decompression, which produces maximum CPU efficiency and smooth editing.

Q: 7. I have an Asus Gaming laptop w/HDMI port. Using Adobe Premiere Elements to capture live DV. Will this device allow me to capture video?

A: This unit currently supports MAC operating software only. However Windows support will be coming soon, but that will work with Premiere Pro, not Elements. Also you will need a PCI Express Port on your laptop to connect it, the HDMI Port on your laptop is for outputting a monitor signal. You will not be able to capture video through that HDMI Port. You may want to look in to something like the Startech USB 3.0 Video Capture Device. This would allow you to capture a wide variety of inputs, it has included recording/streaming software and is compatible with Windows computers.

Q: 8. Does Thunderlink NS 3252 support link aggregation of the two 25GbE connections?

A: Yes, the ATTO Technology ThunderLink NS 3252 Thunderbolt 3 to 2-Port 25GbE (SFP28) Adapter (US Power Cord) supports IEEE 802.3ad link aggregation.

Q: 9. I have an older Macbook Pro (around 2008). Will this work?I want to capture video from the component output of my old Sony HVR Z1U camcorder to 1080p in Final Cut Pro or Adobe Premiere Pro.Will this do it?Many thanks.

A: Sorry update: Not my Macbook Pro. My Mac Pro (tower).Couldn't find a way to edit the original question.

Q: 10. So I know this connects to a QNAP NAS, but can I use this card for the PC end?

A: The QNAP QXG-25G2SF-CX6 Dual-Port 25GbE PCIe 4.0 x8 Network Expansion Card can be used in systems other than just the NAS.
