Mikrotik CRS312-4C+8XG-RM network switch L3 10G Ethernet (100/1000/10000) 1U White

for the price would not turn back. easy to setup and can use out of the box as l2 switch. would suggest replacing the fans (will kill the warranty but will save your ears)

Great layer 3 switch!! A L3 switch is a switch with routing features, so his performance as a switch is equal or better than a layer 2 switch with similar features; the difference is in the routing performance: his performance is a bit lower than a pure router (with the same features). This is because the main motherboard hardware of the L3 switches is built to be a high performance switch. The main motherboard hardware of the routers is built to execute routing tasks, so a router is better than a L3 switch in these tasks. To compare their routing software performance, just see their software routing features (L3 protocols, etc). The performance of a router is mainly measured by his routing hardware capacity, not by his routing software features because the software features are added just buying/installing/enabling a software license and/or changing the NOS (Network Operating System). You can compare their routing hardware performance (between a L3 switch and a Router), looking for the packet throughput (measured in pps (packets per second)) and the total BW throughput (in Gbps) in each brochure/datasheet The CRS312-4C+8XG-RM has a packet throughput of 178 Mpps (is called forwarding rate) and a BW throughput of 120 Gbps The switching performance is measured by the switching throughput also called switching capacity, 240 Gbps for the CRS312-4C+8XG-RM => it is good as router and very good as high speed switch. L3 Switches are good "cheap" solution for small enterprises or SOHO networks, because they replace the router and switch functions, all in one box. If you really need more performance, then you go for a separate real router and a high speed L2 or L3 switch. The CRS312-4C+8XG-RM has only 12 available physical interfaces. 8x10Gbps interfaces and 4+4 combo 10Gbps. The combo interfaces are physically 8 (4 copper RJ45 jacks and 4 SFP+ modules) but you can use only 4 at the same time, so can only have 4 active links. For example, if you insert a copper cable link in the 1T RJ45 combo1 port and also a SFP+ cable link in the 1F SFP+ combo1 port, only the 1F port will be enabled. The SFP+ port has priority over de RJ45 jack port , in the combo interfaces. When you remove the SFP+ module, then the RJ45 jack port becomes immediatly enabled/active. In summary, 8 x 10Gbps copper interfaces plus 4 x10Gbps copper/SFP+ interfaces, total max 12 enabled/active interfaces (only 12, never 16). I recommend upgrading the routerboard firmware (use the 6.48.2 stable or higher) and the packages, using RouterOS 6.48.2 stable version and never install the default-configuration. As a professional Network Engineer, I ALWAYS use the command line to configure the networking devices, so I recommend using it. AFTER upgrading the default firmware to the 6.48.2, the fan noise is really quiet (as Ubiquiti routers); just each 2 hours approx. it starts a short cooling process (a couple o minutes) with a more loud noise (is not annoying) and next continues in its silent mode. This kind of device is in the professional segment, so it is for pro networks and is designed to be configured by professionals => not recommended for beginner users because you need to know what you want, the network protocols that you want, how they work and then learn to use the RouterOS cli (Winbox is good for amateurs or to monitoring, but limited for advanced/expert configurations). That is why I recommend this dog for network engineers. If you know other cli 's like Cisco IOS, etc, is pretty easy and quick the learning curve! This is an small Aggregation L3 professional switch. If you are beginner in networks and you are not pressed, the learning curve could be long but you could learn and practice a lot of features/protocols of Routing & Switching and even Network Automation (yes! You can do Network Automation on MikroTik using Python!)

Der MikroTik CRS312-4C+8XG-RM ist ein richtig solides Arbeitstier. 8× 10GBase-T und 4× Combo-Ports bieten viel Flexibilität, gerade wenn Kupfer und SFP+ gemischt werden sollen. Verarbeitung ist top, Lüfter laufen leise und das Gerät passt sauber ins Rack. RouterOS bzw. SwitchOS bieten extrem viele Möglichkeiten. L3-Features, VLANs, LACP, Routing – alles da. Man sollte aber wissen, was man tut. Kein Plug-and-Play wie bei Consumer-Switches, sondern klar auf Admins und Homelab-Nutzer ausgelegt. Performance ist stabil, auch unter Dauerlast. Für Virtualisierung, Server, NAS oder Backbone im Heimnetz absolut geeignet. Pluspunkte: 10G auf Kupfer ohne Gefrickel Sehr flexibel konfigurierbar Gute Performance, stabile Firmware Preislich fair für die gebotene Leistung Minuspunkte: Einarbeitung nötig Webinterface nicht jedermanns Sache Fazit: Wer einen leistungsstarken 10G-Switch sucht und sich mit MikroTik auskennt (oder es lernen will), macht hier nichts falsch. Klare Empfehlung für Homelab und kleine bis mittlere Profi-Setups.

I really needed a 8 ports 10gbe Switch, was looking at Netgear: easy set-up but too many quality trouble for the high pricing... Then I looked at Mikrotik, many ports , great reviews , but can I set it up? I went for Mikrotik and I don't regret. I am in Japan... My questions before purchase were answered instantly. The order was shipped from Latvia the day I ordered it and by Fedex!!! (shipping was only 40$). It arrived in no time, set-up by a real pro (Chris)that I founded on Fiverr, and finally a great switch at my office. Finally,the noise question: before setup I plugged it with my 10gbe NAS and 10gbe MacMini. Noise was very loud. After setup (and a firmware upgrade) the switch became very quiet.

Switch 10GbE de 8p de cobre+4 puertos combo cobre/sfp+. Todos los puertos de cobre soportan auto negociación 10G/5G/2.5G/1Gbps. Cuenta con 4 ventiladores lo que no lo hace apto para entornos domésticos donde el ruido puede ser un problema. Arranque dual ROS/SwOS, soporta todas las características avanzadas de un switch gestionable, VLAN, RSTP, access list, etc… Producto sólido y con un rendimiento increíble.

I bought this switch as I needed 10Gbps throughput for doing vMotion for my VMs. This switch not only provides the advertised 10Gbps speeds but also a ton of features which I probably will never use. Probably an overkill if you ask me, but this product is priced far more affordable than other 10Gbps switch offerings.
