The Solarflare SFN5122F Dual Port 10GbE Server Adapterfrom Solarflare SFN5122F Dual Port 10GbE Server Adapteris an IEEE 802.3ae/802.3ad/802.1Q/802.1p/802.3x compliant adapter. It delivers high message rates and low latency jitter with 40 Gb/s bi-directional line-rate performance. The adapter supports optical and copper SFP/SFP+ modules, direct-attach, Fiber (10G or 1G), 1G/10G combo, and 1000BASE-T SFP modules. It distributes IPv4/IPv6 loads across CPU cores and MSI-X minimizes interrupt overhead with Receive Side Scaling (RSS). Intel QuickData technology uses host DMA engines to accelerate input/output. This server adapter supports data networking with concurrent support of iSCSI and NAS traffic.

The server adapter delivers low latency along with full 40 Gb/s bi- directional line-rate performance. Featuring a set of stateless offloads, it provides efficient acceleration of network protocol tasks.

The adapter supports Solarflare's OpenOnload application accelerator, a full-featured 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.

With additional vNICs and virtual PCIe functions, input/output performance scales as the number of CPU cores and virtual machines increase, resulting in enhanced application performance. The server adapter accelerates guest applications in hypervisors, supporting NetQueue and VMQ in VMware and Hyper-V, and SR-IOV in KVM and XenServer. It eliminates network input/output barriers hidden in virtualized environments, allowing IT managers to allocate full network resources directly to virtualized applications. The adapter enables high performance and low CPU utilization in virtualized servers.

It consumes 4.9W power and delivers 5 to 10 times the efficiency of 1G Ethernet (Gb/s/W). This results in a power efficient 10G network, saving operating costs for a typical data center. In addition, the adapter is compatible with the ENERGY STAR guideline for power consumption.

Related Questions and Answers

Q: 1. Can I install this card in a Mac (older Mac Pro that allows addin cards)?

A: This card was designed specifically to work with QNap NAS.

Q: 2. Is this rated for 10 GbE speeds?

A: Data Transfer Rate: 10/100/1000 Mb/s

Q: 3. What is the difference b/w QNAP QSW-2104-2T and QNAP QSW-2104-2T-A models?

A: The QNAP QSW-2104-2T is the QNAP QSW-2104-2T-A. The full model number of the QNAP QSW-2104-2T 6-Port 10GbE/2.5GbE Unmanaged Switch is QSW-2104-2T-A-US.

Q: 4. Can I use one of the 2.5GbE ports as uplink port to my router? I want to keep the 2x10GbE ports for my Mac and nas. Thanks in advance!

A: Technically, yes, you could use one of the QNAP QSW-2104-2T 6-Port 10GbE/2.5GbE Unmanaged Switch's 2.5GbE ports for uplink, but then the switch will only be able to provide a 2.5GbE connection to your network for all other devices. In other words, your 10GbE ports can only provide a 10GbE connection to the router if the uplink port is also 10GbE.

Q: 5. How much lfm does it have ?

A: Intel does not provide a LFM rating for this Single-Port Gigabit Ethernet Server Adapter.

Q: 6. Does this allow link an existing gigabit ethernet router with link aggregation? I.e. us e.g. two gigabit ethernet connections

A: No, the 10GbE switches will not do link aggregation. However, since the existing device is 1GbE then any of the BS-GS series switches will do this.BS-GS2008Gigabit Smart Switch 8-Port Metal Chassis Lifetime WarrantyBS-GS2016Gigabit Smart Switch 16-Port Metal Chassis Lifetime WarrantyBS-GS2024Gigabit Smart Switch 24-Port Metal Chassis Lifetime WarrantyBS-GS2048Gigabit Smart Switch 48-Port Metal Chassis Lifetime WarrantyBS-GS2008PGigabit Smart Switch POE 8-Port Metal Chassis Lifetime WarrantyBS-GS2016PGigabit Smart Switch POE 16-Port Metal Chassis Lifetime WarrantyBS-GS2024PGigabit Smart Switch POE 24-Port Metal Chassis Lifetime Warranty

Q: 7. what's the differnce from https://www.bhphotovideo.com/c/product/1643881-REG/qnap_qsw_2104_2t_us_plug_play_switch.html ?

A: There is no difference in specs between the QNAP QSW-2104-2T 6-Port 10GbE/2.5GbE Unmanaged Switch and the QNAP QSW-2104-2T 6-Port 10GbE and 2.5GbE Unmanaged Switch.

Q: 8. is this compatible with osx 10.11?

A: I am sorry it would not, this is only compatible with Mac OS X 10.6 to 10.9

Q: 9. Is this a clone of the discontinued Aquantica AQN-107 ? That was a GREAT NIC !!!!

A: I wouldn't say this would be a clone, it is a highly reviewed network card.

Q: 10. What is the origin? Is it made in USA?

A: The country of origin is Thailand.

I have purchased these cards numerous times for PCs with instruments (GC/MS, FTIR etc) connected to them and they have always worked. Cheap and reliable always a winner. 5

I purchased it 6 1/2 years ago and have had exactly no problems. I have not found it particularly noisy, but I have enough other fans near it that that I don't notice it. 5

the lan port on my motherboard somehow stopped working so i put this into an open pcie slot and it worked great. no download of drivers or anything else. it just worked. as fast as when i had my motherboard 5

I have been using this in my TS-453D QNAP NAS for about two weeks and I am very happy with the price to performance ratio. I have it connected to my MikroTik 10GbE switch and it's been rock solid - no network disconnects and I max out the transfer speeds allowed by my drive array. I highly recommend getting one of these if you want to add 10GbE networking to your QNAP NAS. 5

Takes advantage of my new router. Easy install and setup. Nice speed improvement. 5

Awesome switch. For less than 500.00 you can interconnect 10 gig/5 gig/2.5 gig/1 gig devices on your network. I have used this with high end 10 gig Intel cards, and low end cheap Aquantia 10/5/2.5 Gig cards. Works great with all of them. Even get 10 Gig over short runs on Cat 5E. (around 50 feet). The web interface is a little on the plain side, but at his price I don't care. VLAN tagging works also. Not really loud, but not quite either. It's not a home office switch meant to be located near your computers. I don't believe they market it as that. I have mine installed in my basement back where all my network cables terminate and if your 10 feet away from it, it just sounds like some quiet fan noise in the backgound. No where near as loud as a data center switch. 5

Works good just as advertised 5

Comes bundled with a CAT6A cable, low profile, plug n play, affordable price. 5

B&H had a great price. QNAP TS-259D was an easy set-up. ALso purchased the QNAP 10Gbe Network Card from. It installed easily and was discovered immediately by QNAP OS on next NAS boot-up. All around great experience with B&H. 5
