Linking 2.5GbE and 10GbE connections
Linking 2.5GbE and 10GbE connections
I need to understand the setup clearly. My laptop and next computer both support 2.5GbE, but I’m considering a NAS with either 2x1GbE or 10GbE. I want to know how challenging and expensive it would be to build a reliable home network with strong Wi-Fi while connecting my 10GbE NAS and 2.5GbE devices to a switch. Should I connect directly via modem → switch → [wireless router, computer, NAS]? I’m looking for switches that handle both layers—layer 2 and layer 3—and I’m unsure what features are important. Since I’ll be purchasing in China, I’d prefer a Chinese manufacturer.
The switch activates after the router, not before it. Multi-gig switches remain somewhat costly, but I’m happy with the purchase. For just two fast ports, the Netgear GS110EMX is sufficient. If you require more, the MS510TXP works well. To stay within a tight budget, assuming the NAS card supports multi-gig speeds, a much cheaper unmanaged 2.5Gbit switch is an option. I’m pleased I chose at least a smart-managed model, since I faced slow performance issues with Gigabit clients to my 10Gbit NAS, which I had to fix by enabling flow control on the switch. Interestingly, that issue appears resolved now.
Ten gig ports aren't always compatible with 2.5 gig; if they lack support, they should switch to the highest speed available (Gigabit). You don't require Layer 3 managed switches when all devices stay on the same network segment. Based on availability and pricing, it could be more economical to purchase ten gig interfaces for your machines now and use a refurbished switch to connect them, rather than buying a dual-compatible switch.
It looks like you're considering a 2.5GbE setup. You might want a router with one 2.5GbE port and use the other ports for NAS traffic via aggregation. Going all-in on 10GbE for just one port doesn't seem necessary. I don't think buying second-hand gear in China is a good idea, and used networking hardware isn't as common as you might think.
Make sure the switch and NAS can handle LA on both sides. Because you're sourcing from China, check out the ServeTheHome videos.
Link aggregation is limited to Gigabit speeds only if the router actually supports it. I haven’t successfully implemented SMB Multichannel myself. High-quality networking gear is widely available, but enterprise equipment tends to be built for long-term use. ServeTheHome has also evaluated 2.5Gbit devices from China, though I’d favor a product with a valid warranty from your home country.
You checked out both videos last night. I wasn’t familiar with hasivo and thought TP-Link would perform better. My wife plans to link her gadgets via Wi-Fi, and most will be wireless, so the key is delivering the 2.5 GbE connection to the wireless router.
The used market here is quite interesting. XianYu offers a wide range of affordable second-hand business items.
