10Gtek® 10Gb PCI-E NIC Network Card, Dual Copper RJ45 Port, with Intel X540 Controller, PCI Express Ethernet LAN Adapter Support Windows Server/Windows/Linux/ESX, Compare to Intel X540-T2

Product Information

CX4 was the first 10 Gigabit copper standard published by 802.3 (as 802.3ak-2004). It uses the XAUI 4-lane PCS (Clause 48) and copper cabling similar to that used by InfiniBand technology with the same SFF-8470 connectors. It is specified to work up to a distance of 15m (49ft). Each lane carries 3.125GBd of signaling bandwidth. All the recommended solutions support multiple drive configurations (RAID) for drive failure protection and performance enhancements

Roman Shein said:PCIE 3.0 is 8GT/s with a very small overhead ( encoding scheme to 128b/130b). x1 should be more than enough for any reasonable use case. Unless you are a sole user of a giant NAS w dozens of HDDs & huge write cache, or better an all-flash array ("as seen on Linus YT"). Anything less than that will not be able to read/write data fast enough to saturate NICs in a x3.0 slot (the limit should be around 7.5Gbps). NAS supports RAID that provides protection against drive failure and data loss.

Because the speed of sharing has now finally caught up to the performance of the storage industry—which means less time wasted. Transferring files now takes 90% less time than before.” said Allen, a TP-Linkengineer,and aNAS lover.

Gigabit Ethernet (10GbE) - ( Data rate: 10Gbit/s - Line code: 64b/66b × NRZ - Line rate: 10.3125 GBd - Full-Duplex) [19] [20] [12] To distinguish SMF from MMF cables, SMF cables are usually yellow, while MMF cables are orange (OM1 & OM2) or aqua (OM3 & OM4). However, in fiber optics there is no uniform color for any specific optical speed or technology with the exception being angular physical connector (APC), it being an agreed color of green. [27] With the arrival of 10 GbE, we were able to move the RAID hard disk array into another room and yet retain performance as if the drive was still directly connected to the iMac Pro. It’s been absolutely wonderful editing and working in silence. Conclusion Both are able to achieve the same transmission rate of 10 Gbps (10,000 Mbps). Of the 10 GbE switches currently available, some are equipped with RJ45 ports only, some come with SFP+ ports and some devices offer both for maximum compatibility.

After you’ve got everything plugged in and ready to go, there’s just one small step left. In your NAS and all of your connected devices you need to set the Jumbo Frame (also known as “MTU”– Maximum Transmission Unit) to 9000. On your NAS, this step can be carried out in Network & Virtual Switch. On Windows and macOS this setting can be configured by going to your network adapter properties/settings. Just because 10 GbE exists doesn’t mean that you should necessarily rush out and upgrade from Gigabit Ethernet. There's also the option of buying older SFP+ cards and using RJ45 to SFP+ transceivers if you must use ethernet cable.

These advances were subsequently standardized in IEEE 802.3cp-2021 with reaches of 10, 20, or 40km.Optical fiber [ edit ] A Foundry Networks router with 10 Gigabit Ethernet optical interfaces (XFP transceiver). The yellow cables are single-mode duplex fiber optic connections. Real-time applications such as voice and video conferencing, such as Zoom and Skype, are particularly sensitive to latency. Wi-Fi connections generally add several milliseconds (typically 3-10 ms) to minimum latency and often experience latency spikes that can wreak havoc with delay-sensitive applications. The 10GbE standard encompasses a number of different physical layer (PHY) standards. A networking device, such as a switch or a network interface controller may have different PHY types through pluggable PHY modules, such as those based on SFP+. [4] Like previous versions of Ethernet, 10GbE can use either copper or fiber cabling. Maximum distance over copper cable is 100 meters but because of its bandwidth requirements, higher-grade cables are required. [a] Potentially of more significance for the home users is the fact that SFP+ offers lower power consumption per port (about 0.7 W compared with about 2-5 W for 10GBASE-T, depending on cable length). The greater the number of 10 GbE ports on a switch, the greater the power consumption advantage of SFP+. Against this, the big advantage of 10 GBASE-T is the ability to use existing, affordable copper cables. Feel free to fit your card into an open ended 1x slot for a 7.9GbE card but dont expect a manufacturer to ship it that way
