How to have two networks on Windows Server to handle different workloads?

[Artorevs]

I have this network layout in my little enterprise, attached on a Visio file (the continuous line ones). Right now, our main storage is on the DC (a Windows Server Standard 2016 machine, with Essentials Experience role installed), on a Storage Spaces matrix, and our backup solution was WSE routing client and server backups to a 4 TB WD My Cloud NAS. Until now, we worked very well with this setup, because our network is full Gigabit ethernet, and we had not bottlenecks with file handling, because client backup and storage had different routes, and DC and main storage backup was made in midnight. That was in the past, because now we need to improve our backup strategy ASAP. Our NAS died a month ago with a power surge, and all our DC, main storage, Hyper-V and client backups said farewell in that terrible moment.

 

Right now I'm doing backup in a 4 TB external HDD on my DC, and fortunately we didn't had lost really anything, but as you can know, this isn't the best bandwidth-friendly way to handle this. DC is always full bandwidth, so bottlenecks during certain hours are constant, and we don't want to take a risk again with a simple NAS unit. So, I got with an idea: Create a dedicated storage and backup server, like Linus Tech Tips guys, and work in that way. I handled to buy 3 10 Gbps PCI-E cards, one for each server, 3 SPF+ cables and I'm waiting the arrival of a Quanta LB6M switch to complete the array.

 

There is only a small inconvenient: I don't know how to interconnect with more than 1 NIC the servers, hahaha

 

I know no body is perfect, so I admit it, I don't know how to implement multiple networking layers, and I really hope you guys can help me (I'm too much into this project to quit right now, hahaha). I have the powerful enough virtual lab to test anything you suggest me, so feel free to tell me how to do this (make the dotted lines in my diagram work seamlessly), and I will practice that in the moment (anyway, I don't have too much to do while waiting for the arrival of my network switch).

 

I will be very grateful with all of you for this.
