Cisco switches tend to be rock solid - have worked with them professionally in a couple of data centers.

 Used ones CAN be quite cost effective, as the older ones get retired in favor of newer higher-throughput ones.

 10Base-T is PLENTY of bandwidth for a lot of miners on one switch - 100Base is overkill though you can't find new switches any more at less than 100Base and even THOSE are starting to dry up as Gigabit cost gets close.

20 24 Port TPlink Switches. Either 100Mbps or 1000Mbps

Use a class b subnet 255.255.0.0

split the miners into 2 subnets

172.16.1.x
172.16.2.x

A Asus router with a built in VPN would be good so you can access the machines remotely.

Do you have any recommendation on the network switch and modems to use for medium scale mining? Thanks.

Since mining requires very low actual bandwidth we use Cisco SF200-48 48 port smart switches. We have 36 miners per rack and use 1 switch per rack. Plenty of extra ports. They are solid switches and the older 10/100 model is always being retired from data centers who are upgrading to Gigabit, so they can be had pretty cheap second hand. Flash the latest firmware and they are good to go and have a pretty decent user interface. 10 of them + 1 spare will handle your whole farm. Pickup a good Cisco CCNA training guide and it will tell you how to do the rest like setting up subnets and your IP routing.

Most of my network infrastructure runs on Netgear "blue box" professional-grade switches, though I do have one very old 3Com 100BaseT switch still in use and a friend recently gave me an old "Dell" (by Cisco I think) switch that isn't in service yet (48 100BaseT and 2 Gigabit BaseT ports).
 Mostly FS108 models, with one GS105 and a couple GS108 on recent purchases (they were on sale at the same price as a FS108 when I bought those).

 I made the mistake ONCE of buying one of the Netgear "silver plastic box" consumer-grade switches - it barely made it past warrenttee period before it died, shortest-lived switch I have ever had.

 I USED to have one of their blue-box 8 port 10Base-T "hub" models, but after 15+ years of service that one finally died on me - it was bought used in the first place, dunno how old it REALLY was when it died.

Thank you for this information. I am so naive most of what you said is very new to me. So I will have to do more research on it and maybe I will have more questions on what you have said above. Thank you so much for providing the feedback.

You really should hire some techie to do contract work for you. I just got a used 48port for $18 shipped. Price went up to $30 tho.

400 miners = 400 network ports so you need 40 switches 10 ports each or 20 switches 20 ports each  Grin



Very funny Grin Tongue, I meant which brand to use  Smiley

What do you mean by medium scale?  Numbers would help, otherwise we're all just guessing.
