Knonwing that chinese sfp tranceivers id cheaper than us, so i check on slickdeals, it is amazing i find 10gtek, which is a china factory in china, i purchase the poe switch on slickdeal by a editor showed. though he give a wrong link of the items he shows, i find their online shop is really cheaper than amazon or ebay. https://slickdeals.net/f/13317298-300w-24-port-gigabit-ethernet-poe-switch-10-100-1000m-for-69-90-fs?fbclid=IwAR16BnNp48l2FUNpvWuMFufm2e7rebKQD-6A3qkn9pjMSh6IR-8ZsLDTdi4

If you're running an older VMWare release, you're probably fine. If you're running Windows Server (or desktop), you're definitely fine. If you're running VMWare 6.5 or 6.7...order something else. It's not for a lack of trying.This card has an Intel chipset, so I'm thinking 'oh, it's pretty well supported'. Card says VMWare support as well, so I order it for a client..and then promptly proceed to have it not-detected. Found people saying that it works after a firmware upgrade, so I went down that rabbit hole. Dell's LifeCycle Controller method won't upgrade it because it's not one of the Dell blessed cards. 10GTek doesn't offer this firmware on their website, and they don't respond to an attempt to get support via Skype...ask me how I know these things. I put the card in a Windows box, and the Dell firmware update wouldn't work there, either - tried that two different ways. Finally came full circle and found the package to update it within VMWare directly. It says it took...and still isn't detected, even after a reboot as shown.So, these cards will likely find a home in some Windows servers somewhere, and to 10GTek's credit, they did function well in the Windows machines, complete with all the pro grade Intel features like VLAN tagging and NIC teaming. But...warning all of those planning on using them in VMWare 6.5++...don't.UPDATE: Added these cards to a set of Windows servers for another client. Added a star because these cards worked well in both the 2012R2 and 2016 servers, without any need for a driver install or configuration. Cards work great with the Ubiquiti 10GbE fiber SFP modules I purchased with them. The individual(s) I've contacted via Skype have been very responsive, pleasant, and helpful. If you have Windows servers, these cards are definitely recommended.

The exact same chip and card design as the Intel and IBM branded ones we were buying at my work, for 1/4 the price -- barely any more than you'd pay for used ones. Genuine article, worked beautifully. There are newer generation cards, but other than converged SAN HBA modes this has all the features you'd actually care about (including SR-IOV for virtualization) and because the chipset is a little older the drivers are rock stable under any of Windows, Linux, or ESX. I'm not sure if the SFP+ ports are locked (the Intel branded retail cards we got at my work were) so I got an "Intel compatible" SFP+ module to use with this; the same seller has them at a very fair price 10Gtek for Intel E10GSFPSR, 10Gb/s SFP+ Transceiver, 10GBASE-SR, MMF, 850nm, 300m and it worked flawlessly. Works with un-locked passive Twinax cables as well; have not tried active Twinax. Now it is on slickdeals with a lower price cut less 10$ than i got there, good choice! https://slickdeals.net/f/13296346-10gb-s-ethernet-converged-network-adapter-compatible-for-intel-x520-da2-for-106-20-fs?fbclid=IwAR0Qo4uRLumhmeLZMzrk3NHetGJ6kSWuko22uaWmzrIo-feFu4R912gcwGc

after test, it is ok already. https://www.sfpcables.com/ethernet-converged-network-adapter-x520-da2 i order with $106 use code:SFPcables8

Got this to fix issues with the onboard Realtek NIC for my FreeNAS server. This thing is amazing, haven't had a single issue with networking as I had prior with the onboard NIC. Similar, if not better throughput as other 1 Gbit NICs. I ordered the 82574L EXPI9301CT for a lab project at work. Never accomplished transfer speeds over 80Mb/s. Tested on Windows server, pfSense and a RedHat box, with Intel drivers installed without accomplishing higher transfer speeds. Never had issues with 10Gtek products until now.
