Solarflare - SFN5122F - Dual-Port 10GbE SFP+ Enterprise Server Adapter

The Solarflare® SFN5122F dual-port 10G Ethernet SFP+ enterprise server adapter delivers the industry's best application performance, lowest power consumption, and most scalable virtualization, enabling unmatched performance and scalability for enterprise data centers.

SFN5122F SFN5122F

The SFN5122F is designed to address issues facing data center managers today. Equipped to handle the application loads of the latest multi-core processors, it delivers unmatched performance scaling for high-density server deployments, while utilizing a single driver across all Solarflare server adapter products. The SFN5122F supports data networking with concurrent support of iSCSI and NAS traffic – while remaining true to the need for cost effective, power-efficient and high performance network I/O.

Application Performance Leadership

SFN5122F delivers the industry's lowest latency at the highest message rates to customers with leading edge enterprise data center deployments. SFN5122F also delivers the industry's highest message rate and lowest latency jitter, with full 40Gbps bidirectional line-rate performance. Featuring a rich set of stateless offloads, it provides efficient acceleration of the most demanding network protocol tasks.

SFN5122F supports Solarflare's OpenOnload® application accelerator, a full-featured, high performance user-level network stack for Linux. OpenOnload provides unprecedented performance with application compatibility and protocol compliance, bypassing kernel and networking overheads, while featuring binary compatibility with standard APIs and applications.

Scalable, Hardware-Assisted Virtualization

The SFN5122F is designed to optimize virtualized application performance and maximize the use of network resources. With 10x the number of vNICs and virtual PCIe functions than the competition, I/O performance scales as the number of CPU cores and virtual machines increase resulting in enhanced application performance supporting more applications per physical server.

The SFN5122F accelerates guest applications in leading hypervisors, supporting NetQueue and VMQ in VMware and Hyper-V, and SR-IOV in KVM and XenServer. SFN5122F relieves network I/O bottlenecks hidden in virtualized environments, allowing IT managers to allocate full network resources directly to virtualized applications. SFN5122F enables the highest performance and lowest CPU utilization in virtualized servers.

Lowest Power

At less than 5 Watts, the SFN5122F consumes less than half the power of the leading competitors' products, and delivers 5 - 10x the efficiency of 1G Ethernet (Gbps/Watt). This not only makes a power efficient 10G network possible, it can save thousands of dollars of operating costs for a typical data center. The SFN5122F is also compatible with the Energy Star® guideline for power consumption.

5 out of 5 eggsGreat quality at a good price

Pros: This is a great 10Gb NIC not only for the price but for the quality you get as well. I picked up two of these and they worked without any issues. I installed one in a Debian based server and the other in a Windows box. For the price and performance you get out of these they are definitely some of the best I have encountered.

Cons: Windows 7 needed some extra tweaking to get decent speeds out of these cards but other than that they worked flawlessly.

Other Thoughts: To get the drivers to work on a Debian based system you need to repackage the Linux RPM drivers on the Solarflare website and then make the installer. You can find instructions all over on the exact steps to do it but once that is done they work just fine on Debian based systems too.

4 out of 5 eggsGood Price, Works

Pros: Price: they are not exactly cheap but there are far more expensive options out there and these get the job done.

Size: They fit in half-length slots and are not very long either.

Cons: Compatibility: I bought some cheap SFP+ transceivers that don't work in the NIC but do work inside my switch.

I bought a couple decent transceivers and a couple cheap ones, I have to put the decent ones into the NIC for anything to work but the cheap ones work in my switch no problem. Can't get the cheap ones to light up in the NIC.

I'm only taking 1 star for this because I know transceivers are a pain in the...

Other Thoughts: I'm seeing ~ 550MB/s SSD->SSD (RAID0s) over SMB (4.5Gbps) and iperf only shows about 7Gbps regardless of the number of flows. This is with 9000 MTU between Windows 8.1 and Server 2012 R2.

I don't have anything to compare it to, it seems a little low but it sure beats 1Gbps or NIC teaming a bunch of cables.

5 out of 5 eggsGood Cheap 10Gb for ESXi

Pros: Using for data & iSCSI traffic on ESXi 5.5 servers direct-connected to HP switches. Speed is not an issue with this card. Great for small to mid-size enterprises, cheap enough for desktop use (if you have 50 micron fiber running all over, and who does that?)

Cons: Although this is on the compatibility list at VMware, my DELL media loaded ESXi 5.5 boxes did not have drivers, so I did have to SCP the drivers onto the box & run a manual iinstall/reboot required. If I used Intel, I likely would not have had that problem.

Other Thoughts: I'd buy them again, the downside is, if I upgrade the ESXi version, I will likely have to reinstall the drivers again, All my servers have multiple NICs, so it's not a huge problem, just adds 10 minutes to every upgrade, which is not that frequent. For the money, they are awesome.

5 out of 5 eggscompatible with cheap fiber sfp, easy, fast

Pros: simple installation for hackintosh and debian
works with 3m sfp+ cheap long fiber cables ( ~100 - 150 ish price depending )
solarflare is viable ongoing high end company, myricom just got bought out by some defense contractor

Cons: none

Other Thoughts: vs cat6 version, newegg awesome price made the total cost cheaper than 1 brandX 10g card.
