First off, we're a small business and don't have an IT guy, I know a little, but it's not my job. We'll hire someone to do any necessary work but I'd like to understand what we can do first.
Our network is currently composed of 3 Unifi us-24-250w switches providing PoE for some IP phones and gigabit connections to a few computers. There are also some Unifi wireless access points, I believe routing is being done by a SonicWall TZ400, as it's my default gateway (???).
One part of our business involves a half dozen or so computers which are constantly moving large files over the network from a single storage server. Its a bottleneck in our production and I'm about to upgrade the server computer to have an SSD for those files, or get a NAS with RAID, But even in that case, our 1Gb network can only move 125MB/s and an SSD can do ~2000MB/s.
I would like to upgrade these half dozen computers to a 10Gb network, just so they can communicate with each other and the file server more quickly, but I don't know if I need to upgrade anything else.
The building is wired with Cat6 so I was looking at something with 10GBASE-T, either this QNAP QSW-1208-8C-US or to keep everything consistent, this Unifi US-16-XG, but I like that the QNAP has enough RJ45 ports. Then I'd get some 10Gb PCI-e cards for the PCs in question.
Now to my actual questions:
- Can I simply add a 10Gb switch to my existing 1Gb network?
- Do I need a 10Gb router as well, to avoid that 1Gb bottleneck, or is it ok since all the 10Gb stuff is going through the one switch?
- Is there a better way for a half dozen computers, all in the same room, to have 10Gb or similar speed to a file server?
