Frequently Asked Questions
What is the Mellanox ConnectX-6 MCX653105A-HDAT?
The Mellanox ConnectX-6 MCX653105A-HDAT is a high-performance single-port VPI network adapter designed for server and data-center networking, high-performance computing (HPC), AI infrastructure, cloud networking, distributed storage, and other high-bandwidth applications. It features one QSFP56 port and a PCIe 4.0/3.0 x16 host interface.
What speeds does the MCX653105A-HDAT support?
The MCX653105A-HDAT supports Ethernet speeds from 1GbE through 200GbE, including 10GbE, 25GbE, 40GbE, 50GbE, 100GbE, and 200GbE. In InfiniBand mode, it supports SDR, DDR, QDR, FDR, EDR, HDR100, and HDR, with HDR providing up to 200Gb/s bandwidth.
Does the MCX653105A-HDAT support 200GbE?
Yes. The MCX653105A-HDAT supports up to 200GbE Ethernet connectivity. Supported 200GbE interfaces include 200GBASE-CR4, 200GBASE-KR4, and 200GBASE-SR4, depending on the network infrastructure and compatible cable or transceiver.
Does the MCX653105A-HDAT support InfiniBand?
Yes. The MCX653105A-HDAT is a VPI adapter that supports both InfiniBand and Ethernet networking. Its InfiniBand capabilities include HDR at up to 200Gb/s, HDR100, EDR, FDR, QDR, DDR, and SDR. This makes it suitable for HPC, AI, storage, and other InfiniBand-based data-center environments.
What does VPI mean on the ConnectX-6 MCX653105A-HDAT?
VPI stands for Virtual Protocol Interconnect. VPI allows the MCX653105A-HDAT to operate as either an InfiniBand or Ethernet network adapter, allowing the same hardware platform to be used in different high-performance networking environments.
What PCIe slot does the MCX653105A-HDAT require?
The MCX653105A-HDAT uses a PCIe x16 host interface and supports PCIe Gen 3.0 and Gen 4.0. A PCIe Gen 4.0 x16 connection provides the host bandwidth required to take full advantage of the adapter's 200Gb/s networking capability.
Can the MCX653105A-HDAT run in a PCIe Gen 3.0 slot?
Yes. The MCX653105A-HDAT supports PCIe Gen 3.0 operation. However, PCIe Gen 3.0 x16 provides less host bandwidth than PCIe Gen 4.0 x16, and NVIDIA specifies up to 100Gb/s for a ConnectX-6 adapter using a PCIe Gen 3.0 x16 connection.
What connector does the MCX653105A-HDAT use?
The MCX653105A-HDAT uses a single QSFP56 network port. The QSFP56 interface supports compatible copper and optical cables and transceivers for Ethernet and InfiniBand networking at supported link speeds.
What cables are compatible with the MCX653105A-HDAT?
The MCX653105A-HDAT uses QSFP56 connectivity and supports compatible copper and optical networking solutions. The specific cable or transceiver should match the required Ethernet or InfiniBand standard, link speed, and network equipment.
Does the MCX653105A-HDAT support RDMA?
Yes. ConnectX-6 supports Remote Direct Memory Access (RDMA), allowing supported applications and storage systems to transfer data directly between memory resources with reduced CPU involvement. RDMA is a key technology for high-performance computing, storage, and data-center networking.
Does the MCX653105A-HDAT support RoCE?
Yes. The ConnectX-6 architecture supports RDMA over Converged Ethernet (RoCE). RoCE enables RDMA functionality over Ethernet networks and is designed for high-throughput, low-latency data-center workloads.
Is the MCX653105A-HDAT suitable for AI and GPU computing?
Yes. ConnectX-6 supports technologies including GPUDirect RDMA and PeerDirect that can accelerate data movement between supported NVIDIA GPUs and network devices. These capabilities make the MCX653105A-HDAT suitable for high-performance AI, machine learning, and GPU computing infrastructure.
Is the MCX653105A-HDAT suitable for high-performance computing?
Yes. The MCX653105A-HDAT supports up to 200Gb/s HDR InfiniBand, RDMA, PeerDirect, and other ConnectX-6 acceleration technologies. These capabilities make the adapter suitable for HPC clusters and other applications requiring high network bandwidth and low latency.
Can the MCX653105A-HDAT be used for high-performance storage?
Yes. ConnectX-6 provides storage acceleration technologies including RDMA and NVMe over Fabrics (NVMe-oF) capabilities. The MCX653105A-HDAT can therefore be used in high-performance networked storage environments where high throughput and low latency are required.
Does the MCX653105A-HDAT support virtualization?
Yes. ConnectX-6 supports hardware-based virtualization technologies including Single Root I/O Virtualization (SR-IOV). SR-IOV allows supported virtual machines to access virtual network resources provided by the physical network adapter.
What operating systems support the MCX653105A-HDAT?
The ConnectX-6 family is supported across major Linux distributions and Windows environments through NVIDIA's networking software and driver stacks. Ethernet and InfiniBand functionality depends on the operating system, driver package, and configuration being used.
What are the dimensions of the MCX653105A-HDAT?
The MCX653105A-HDAT uses a half-height, half-length PCIe form factor with a tall bracket. NVIDIA specifies dimensions of approximately 167.65 mm by 68.90 mm, making it suitable for compatible server and workstation chassis designed for half-height, half-length PCIe cards.
What is the difference between the MCX653105A-HDAT and MCX653106A-HDAT?
The primary difference is the number of network ports. The MCX653105A-HDAT is a single-port ConnectX-6 VPI adapter with one QSFP56 port, while the MCX653106A-HDAT is a dual-port version with two QSFP56 ports. Both models support up to 200Gb/s Ethernet and HDR InfiniBand networking.
Let customers speak for us
We’ve been using NC for our server hardware purchases, and they’ve been great to work with. Their products and service have consistently met our needs, and we’ve had a very positive experience with them. Highly recommended!
Clean and well packaged
36GB (9 x 4GB) DDR3-1333 MHz PC3-10600R ECC Registered Server Memory Upgrade Kit
Fast, easy ordering and fulfillment quality is excellent. Another super great job.
Donovan always provides extremely quick service, and is super helpful to work with. We generally always have an idea in mind on what we want, and he's able to deliver a quote & product that exceed expectation every time.
This was my third memory order from Cloud Ninjas, and all three have been good. The memory arrived well packed and worked as expected. I used this 12 x 8GB DDR3 ECC registered kit for a server upgrade, and the system detected the full 96GB without issues. Good transaction and I would buy from Cloud Ninjas again.
96GB (6 x 16GB) DDR3-1600 MHz PC3-12800R ECC Registered Server Memory Upgrade Kit
I recently order some memory from Cloud Ninjas. The website was easy to navigate and the pricing was better than I could find elsewhere. Placing the order was simple. The product took a day or two to ship but I understand they test every memory module before shipping. The memory arrived in a plastic memory container which was in a static-free bag wrapped in several layers of bubble wrap. All 8 sticks worked perfectly. I would definitely do business with them again!
The memory arrived well packed and matched the advertised specs. Installed in an ASUS Z11PA-D8 system and was detected correctly by BIOS with no memory training errors. Good value for tested server memory.
The delivery time was decent. I didn't order a GPU, but they included a cheap one to check if the machine posted without hardware modification. Very satisfied!
Nice people, had what I needed in stock at a good price. Went by and picked it up in person. Totally a 5 star experience. Happy to have found them so close to my house!
Ordering from Cloud Ninjas was great! :)
Excellent product and on time delivery.
We are making several upgrades and changes and have not installed the memory at this time. However, the easy ordering and quick delivery was very satisfactory! Thank you!
