putting a 10gbe Switch inside a mostly gigabit network? (alien.top)

Have a small room in our office that there's now multiple video editing stations in.

I'd like to stick a 10GB switch in there. Attach one gigabit line to the network (router etc) and then the NAS to a 10gbe line. and run Cat 6 to the 3 editing stations all which have either 2.5 or 10gbe Nics in them already.

So if the IP's would all be part of the network via the gigabit line, but if the 10gbe switch is in there, will they negotiate and run at 10gbe where possible. LIke being able to talk to the nas from the editing stations at proper 10Gbe?

Or will I need to create a whole new network with it's own router?

I hope I'm making sense, in the very early stages of planning.... apologies for the potentially dumb question :)

no issues, provided the switch and port supports multigig speeds

What lovesredheads_ says is true.

I assume you have 1gb service from your ISP, and it connects to a 1gb router.

ISP --> 1gb router

Now you want to attach that router to your 10gb switch. Yes, that will work.

ISP --> 1gb router - cat6 -> 10gb Switch

then the 10gb Switch connects like this:

===> 10gbe NAS

===> 2.5gb PC 1

===> 2.5gb PC 2

===> 10gbe PC 3

Point 1. At any given time, any device will connect to the INTERNET "up to"* 1gb between all active communications. (they will share)

Point 2. PCs 1 & 2 will be able to connect to the NAS (and to PC 3) at "up to"* 2.5gbe.

Point 3. PC 3 will be able to connect to the NAS at "up to"* 10gbe

*All active devices, while not using LACP, will SHARE the max speed of their local LAN

Point 4. If all 3 PCs are downloading from the NAS at the same time, they are sharing the 10gb. So, PC1's speed is 2.5, PC2's speed is 2.5, but PC3's speed is only 5 (because the other 2 PCs are taking up 5)

Point 5. If PC 1 (or PC 2) is downloading from the internet, it will be at 1gb. But if it's also transferring a file to the NAS, the transfer will be at 1.5gb, because 1gb of its bandwidth is being utilized from the internet.

Point 6. You can have other 1gb devices connected to the 10gb switch and it will not affect the speed of your 2.5/10gb connections (unless those devices are downloading from the internet)

Point 6a. They can also just connect to the router, with no difference.

Excellent! Thank you.
