The bundle of SFN6122F Server Adapter and SFM10G-SR 10GBASE-SR Transceiver from Solarflare includes one SFN6122F server adapter and two SFM10G-SR 10GBASE-SR transceivers. The SFN6122F server adapter is a dual port PCIe generation 3.0 compatible 10G Ethernet SFP+ enterprise server adapter that delivers high message rates with low latency over standard Ethernet. It also enables low CPU utilization and power consumption, providing performance and scalability for financial services and other data center environments.

The server adapter is equipped to handle increasing application loads of multi-core processors. It delivers enhanced throughput and low latency with minimal CPU load, for the consolidation and deployment of high-density servers. The server adapter supports data networking with concurrent support of iSCSI and NAS traffic.

The SFM10G-SR 10GBASE-SR transceiver is a hot-pluggable SFP+ device for use in 10 Gb Ethernet links over multi-mode fiber. It is compliant with the SFF-8431, SFF-8432, and IEEE 802.3ae 10GBASE-SR specifications. The transceiver is RoHS compliant and lead-free per the Directive 2002/95/EC6. In addition, the SFP+ transceiver supports a 2-wire serial communication protocol as defined in the SFF-8472. This low-power module supports OM1, OM2, and OM3 multi-mode fiber (MMF) media with standard LC connectors.

The SFN6122F server adapter delivers low latency at high message rates, making it suitable for financial services and enterprise data center deployments. It also delivers 40 Gb/s bi-directional line-rate performance. Featuring a set of stateless offloads, it provides efficient acceleration of network protocol tasks

It supports a wide range of drivers that are compatible with all Solarflare products, including the SFN5122F enterprise server adapter. The server adapter also supports Solarflare OpenOnload application accelerator, a user-level network stack for Linux. OpenOnload provides low latency performance with application compatibility and protocol compliance, bypassing kernel, and networking overheads, while featuring binary compatibility with standard APIs and applications

With additional vNICs and virtual PCIe functions, the SFN6122F server adapter's performance scales as the number of CPU cores and virtual machines increase, resulting in enhanced application performance. The server adapter supports NetQueue, VMQ, and SR-IOV used to accelerate guest applications in hypervisors, such as VMware, Hyper-V, Linux KVM, and XenServer. This eliminates network input/output barriers in virtualized environments, dedicating full network bandwidth directly to virtualized applications while maintaining hypervisor management services

The server adapter consumes less than 6W of power and delivers 5 to 10 times the efficiency of 1G Ethernet (Gb/s/W). This results in a power efficient 10G network that can save operating cost for a data center. It is also compatible with the ENERGY STAR guideline for power consumption

Related Questions and Answers

Q: 1. Will this support NBASE-T (the ability to auto-negotiate with a switch running at something faster than 1Gb & slower than 10Gb?

A: No, the QNAP Mellanox MFM1T02A-SR 10GbE Transceiver only supports SPF+, it may have problems negotiating with other connection speeds.

Q: 2. Can I connect 3 mono inputs to mix them to the output?

A: No, this adapter can handle either two mono mics, or one stereo mic.

Q: 3. Can this be used with Hollyland Lark Max transmitter?

A: Yes, the Saramonic SR-MH1 Handheld Transmitter Adapter can be used with a Hollyland Lark Max transmitter.

Q: 4. Will this work with Deity D3 Mic?

A: I'm trying to connect the Deity D3 Mic to the SR-AX100 to the Canon 80D. But doesn't work. What am I doing wrong.

Q: 5. Do they come in color

A: No, these only come in black color.

Q: 6. Is the bottom flat? The side that is not pictured

A: Yes the bottom is flat.

Q: 7. The Kopul version of this had a cold shoe mount that was terrible adn would disassemble in the field when the screw fell out of the bottom from too much stress of mounting receivers on it. Does this product suffer the same problem?

A: I worked with Saramonic for 2-years and that whole time, I have not seen any defects of this product, or heard of an issue like you describe. I also have 2 in my possession for those 2-years and had no issue. My best suggestion is to try the item for yourself and if it's not up to your standards, return it for a refund or another product. We also offer a one-year warranty for full replacement if there's any problem. I think you're going to be happy with the product.

Q: 8. Can I plug a stereo plug into the mono input? I have two Saramonic UwMic9s receivers, and want to connect one to each of the mono inputs.

A: As the Saramonic UwMic9s is outputting a true stereo signal, and the L/R inputs on the Saramonic SR-AX100 Passive 2-Channel Audio Adapter for DSLR Cameras are mono, there is a strong chance that each mono input of the SR-AX100 will only pass one side of the signal received by the UwMic9s through the device to the camera, eliminating one of the transmitter signals at this stage.

Q: 9. Can I use it to connect a mixer board to my dslr?

A: No. You would require something with line inputs instead of mic inputs like the Kopul CMX-2-V2. https://www.bhphotovideo.com/c/product/1332706-REG/kopul_cmx_2_v2_two_channel_passive_camcorder.html

Q: 10. what is the latency?

A: No official latency numbers are available, however Anandtech benchmarked this card and found that its average latency is 57ms with 9k jumbo frames, or 63ms with default settings.
