Review: Tricky to find correct drivers - This is not plug and play, you need to find the correct drivers for your OS for the Intel controller that it uses. That isn't as straightforward as it could/should be. Once set up, it certainly can work to specification but I have found some odd performance behaviours that get rectified by enabling/disabling other ethernet adaptors on my system. Very odd. But overall, I'm satisfied. Review: I have multiple Jellyfin servers, and installed 1 10g nic in the Windows platform and 1 in the Ubuntu platform. Ubuntu connected with native drivers and Windows was an easy download, install BAM, both of these budget 10g nic's using DAC cables are getting me 300+ transfer speeds. As for how long they last, well I'll update a review if reliability becomes an issue. They do get hot when loaded for long periods, so I placed a 40mm Noctua blowing directly on just one, so if it dies, temp specifically won't be the factor. So far, a fantastic product, priced right and super fast shipping! ## Features - Ethernet Controller(s): 82599ES Controller, X520-10G-1S - Interface: Single SFP+ Port, apply to SFP+SR and SFP+LR moduleοΌ› Coming with BOTH Low Profile Bracket and Full-height Bracket - PCI Express* 2.0. 5.0 G T/s x 8 Lane,and also suitable for X16 Lane, Please confirm your motherboard slot before ordering, and purchase the network card with correct slot - Cabling Type: SFP+ Direct Attached Twin Axial Cabling up to 10m, Bracket Height: Low Profile and Full Height - Supported Operating Systems: Windows Server 2012 R2*/ 2012*/ 2008 R2*/ 2008* SP2/ 2003 R2*/ 2003* SP2; Windows 8*/ 7*; Windows Vista* SP2; Linux* Stable Kernel version 3.x, 2.6,x; Red Hat Enterprise Linux* 5, 6; SUSE Linux Enterprise Server* 10, 11; VMware ESX/ESXi* ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06WWB5RT7 | | Are Batteries Included | No | | Best Sellers Rank | #88,631 in Computers ( See Top 100 in Computers ) #230 in Network Cards | | Brand | H!Fiber.com | | Color | X520-10G-1S(1xSFP+) | | Customer Reviews | 4.4 4.4 out of 5 stars (138) | | Date First Available | 15 March 2017 | | Item Weight | 181 g | | Item model number | X520-DA1 | | Manufacturer | H!Fiber.com | | Operating System | Windows 8, Windows Server 2012 R2, Windows Vista Service Pack 2 | | Product Dimensions | 22 x 15 x 3 cm; 181.44 g | ## Product Details - **Brand:** H!Fiber.com - **Colour:** X520-10G-1S(1xSFP+) - **Data link protocol:** Ethernet - **Hardware interface:** PCI Express x8 - **Product dimensions:** 22L x 15W x 3H centimeters ## Images ![X520-10G-1S-X8 - Image 1](https://m.media-amazon.com/images/I/61K1cq9EyhL.jpg) ## Questions & Answers **Q: Do you know is this will work in either a Dell PowerEdge 2950 (9th Gen) or PowerEdge 2650 (6th gen) server?** A: Thank you for your question . It could work if your server has PCI-E X8 X16 slot , and supports the operating system that Broadcom BCM57810S NIC compatible. You are welcome to have one to test. **Q: If you insert an SFP+ module that supports both 10g and 2.5g, and connect to a remote 2.5g switch port, will it work?** A: No, the 10G SFP+ network card does not support 2.5G rate. **Q: Does this card work with the cisco sfp+ ??** A: It has worked with every sfp+ cable we have thrown at it, probably a total of 5 various cables coded for different manufacturers. I will say though, we have not specifically tested with Cisco. **Q: Does this card work with server 2016 and esxi 6.7?** A: Yes, HiFiber's 10Gb NIC card for Broadcom BCM57810S could work with server 2016 and esxi 6.7. ## Customer Reviews ### ⭐⭐⭐⭐ Tricky to find correct drivers *by D***R on 12 March 2024* This is not plug and play, you need to find the correct drivers for your OS for the Intel controller that it uses.
