10 gig vs 2.5 gig which should you buy?
Anyone upgrading from 1 gig to 2.5 gig. How about 10 gig? Let me know here what you are running in your home lab or home server environment. I'm curious to know how many have picked up 2.5 GbE switches recently or plan to and also 10 gig.
Check out my post on the topic too:
For me the key was to make sure that my home wiring was able to accommodate the upgrade rather than to simply upgrade the communication speed between lab devices.
Rather than retrofitting my home wiring with cat-6 Ethernet, I chose to deploy MOCA adapters. MOCA (Multimedia over Cable Alliance) adapters allow you run 1 or 2.5Gb (depending on the adapter) Ethernet traffic over your home's existing coax cables. It's an inexplicably obscure technology for how well it works compared to something like powerline Ethernet. I'm using ScreenBeam ECB7250 adapters which have a 2.5Gb RJ45 port.
My topology is essentially point-to point, with an office and basement/lab "site". I have an additional adapter for the living room if I want to add a TV/gaming site in the future.
I purchased 2 KeepLink 2.5G 8-port unmanaged switches from AliExpress for $43 each on Black Friday and deployed one at each site.
A USB NIC in the office provides 2.5G service to my workstation. If I want to add mesh network satellites, they can use the wired network for backhaul instead of sharing a radio and halving the available bandwidth.
In the basement I added a 2.5G PCIe NIC to my Synology NAS. My homelab servers are currently a couple of miniPC devices that have integrated 2.5G NICs. These devices plus the 10G WAN port for my ISP router are connected to the basement switch.
The end result was a relatively inexpensive upgrade that provides a reliable low latency 2.5Gb connection to anything in my home that's plugged in to the wired network. I'm able to fully utilize my ISP's 1.5Gb fibre connection. I'm missing a managed switch for VLAN support and a security device that can provide outbound traffic control.
@termv that is a great setup! It sounds like you have made use of pretty inventive ways to connect at 2.5 gig. What kind of latency are you seeing between nodes with the MOCA adapters etc? I am going to have to check into this technology as I haven't heard of it before. Sounds very interesting.
Do you have direct fiber to your home with the 1.5 Gbps connection? I am currently limited to 1 gig here ☹️
@brandon-lee I'm seeing about 10-11ms of latency to most sites on the external internet. 3.5-4.5ms of that is through my internal network to my router.
That is indeed with a direct fiber connection. They rolled out fiber to the home here a few years ago and it's possible to get up to a full 8Gbps symmetric connection if you have your house wired for 10GbE 🤯
@termv that is incredible. Unfortunately, I live in a fairly rural area and don't have access to direct fiber connections, only Coax. I am waiting to see what the local cable company does to keep up with the increasing speeds of competitors etc. That is crazy on the 8 Gbps full symmetrical connection. Would definitely require an entire retrofit of network wiring and gear for most 🤪 but I would be willing to go for it 🤣
I am in the process of upgrading some of the infrastructure to 2.5gig but I'm mostly using it for the interconnects between homelab hosts for now.
All of the devices on my network wouldn't benefit from anything faster than 1gig yet since they're largely connected via wireless. Inter-transfers within the homelab to/from the new NAS are finally saturating a 1gig link, so I'm looking to tackle that bottleneck first.
One downside to using older 1L tiny-mini-micro nodes though is that I have to use USB3 to 2.5gig adapters. Not ideal, but it is working so far. I picked up an 8-port Mokerlink 2.5gig switch for interconnecting the "production" parts of the homelab. When I eventually consolidate everything into one rack, I'll be able to use the 10gig uplink on the Mokerlink switch to the UDM Pro.
