Good evening,
In our new build, we plan to install two physically separate switches: one on the ground floor and the other on the upper floor.
Until now, I thought I would simply connect the two with the standard CAT cable that I have also run to the outlets.
Now I’ve come across the terms SFP and SFP+.
The two switches I want to use have these SFP ports.
My questions:
- What are SFP and SFP+?
- Why should one use them? Do they enable faster connection between the two devices?
- The two switches I want to use have these SFP ports. Do I just need the appropriate SFP cable, and it will work?
I’ve already searched online but haven’t really figured it out…
Thank you!

.... My work computer has a 10 GbE card and is connected directly to the core switch because I mostly work with data on the NAS. But everyone does it their own way A little off-topic. But a NAS is a NAS is a NAS and is not a server. I can’t stress this enough! Too often, misleading impressions are created by good marketing from NAS manufacturers. @untergasse43 : But if data is stored directly on the NAS, hopefully it’s connected as an iSCSI target for better performance? And regularly backed up? As I said: a NAS is a NAS is a NAS and is not a server. You don’t want to have to “call” Taiwan and have an English-speaking Synology employee try to access your NAS via Telnet because the flash storage failed and the hard drives won’t mount anymore (not even in an identical NAS due to some “nonsense” – right? Or end up in a similarly frustrating situation. Just imagine something along those lines.

Hopefully the NAS won’t be the bottleneck... No.

You don’t want to “call” Taiwan and try to get an English-speaking support agent from Synology to access your NAS via Telnet because the flash PROM crashed and the hard drives won’t mount anymore (not even in an identical NAS due to some “nonsense” – right? Or a similar ridiculous situation. Just imagine something like that. I don’t really understand the point or the problem right now; did I mention a server? I have only one system drive in my PC, and the rest is stored on the NAS, whose drives run in RAID 5 and are mapped as a network drive. Data backup happens automatically to a second NAS located elsewhere in the house, where speed is not that important to me. Just in case someone asks: I obviously don’t reach the theoretical 1250 MB/s (over 10 GbE), but I definitely get much more than what 1 GbE would allow.

knalltüte28 May 2020 08:53Hi, the situation is now clear. You do (automated and verified?) backups. That’s good. Unfortunately, many rely solely on RAID in their NAS and don’t perform separate data backups. It’s RAID... :-(
(they don’t understand what that means)
Even some managers and/or technical staff in smaller companies think this way. Since I’ve seen this quite often in practice, I just wanted to share my observations.
Example from recent months: An old Netgear NAS (>10 years!) running only SMB1 as a server in a company. An external HDD connected, but no backup of the last 3-4 years visible on it. A company with more than 20 employees!
However, partly important data stored in the data center (cloud) of the software provider (SaaS). That’s what I call a full-fledged "backup strategy."
In this case, you are better prepared privately.

untergasse4328 May 2020 09:02It is stated on almost every site dealing with this topic that RAID is not a backup. Years ago, I experienced a very painful data loss, and I learned from it.
Important data, as well as data used externally, is also stored on OneDrive. The mobile Office integration is simply excellent.
