Need help finding a switch

[caplam]

I'm looking to replace 2 switches with one.
Here is what i need:
- 1 uplink with 10G sfp+
- 1 uplink with 1G sfp (maybe upgraded later when i change the switch at the other end)
- 2x10G sfp+ server 1
- 2x25G sfp28 server 2 (will also be ok at 10G) server 2
- 10Gbe server 2
- at least 8x 2,5Gbe ports for router and server 1&2
- 3-4 POE ports (1GBE is enough)
- possibility to setup a mirroring port to mirror traffic from 3 2,5Gbe ports
- vlan management
- lacp
I don't very well networking devices. For now i have a unifi 48 POE and a chinese sks8300 ( 8 ports SFP+).
And if it can be found in europe at decent price it would be perfect.

There aren't a whole lot of options with PoE and >4 SFP ports, and *very* few that add 2.5G+ interfaces to the mix.

The only two that come to mind are both enterprise switches, and they're both fairly expensive (at least in the US) and quite noisy. The Juniper EX4400-48MP (or -24MP) would give you a bunch of RJ45 ports that can do some mix of 10G/5G/2.5G/1G/100M, 4 SFP28s (on an optional card, for extra money), and 2 QSFP28s that can be broken out into 4x25. The Arista 720XP-48ZC2 is basically similar, but it's a bit cheaper and can't to 10GBASE-T, just a mix of 5G and below. The last time I looked at eBay, those were still selling for $1500 and up, though.

One thing to keep in mind is that almost all SFP* interfaces can work at lower speeds, so you can plug a 1G SFP into a 25 Gbps SFP28 port and expect it to work. On larger switches, *generally* speeds are set on blocks on 4 ports, so plugging in a 1G SFP will probably result in a block of 4 interfaces dropping to 1G, although that's less likely with switches that only have 4 ports. Read the specs and possibly the manual for any switch if you need to support wildly varying port speeds at the same time.

Also, generally there's very little point in having multiple links between servers and a single switch. You're better off viewing LACP as being more about redundancy than throughput, and doing LACP between a server and a pair of switches is more useful than having 2 links in parallel between a switch and a server. And adding multiple lower-speed interfaces to that (which I think is what you're hinting at here) isn't usually all that useful, but there are always exceptions. For instance, having a 25G link for data plus a 1G link for IPMI makes perfect sense, although I'd still rather use 2 switches for that if using IPMI for out-of-band management was a major issue.

Most of the time, you'll be better off with a PoE switch plus a SFP+/SFP28 (or faster) switch, as it'll give you a lot more flexibility. There are dozens of 2.5G PoE switches on the market, and probably hundreds of switches with 8 or more SFP+/SFP28 ports, vs a small handful of switches with both in the same chassis.

Thank you for your answer.
I don't use lacp on servers. The server 1 has 2 sfp+ interfaces. one is dedicated as monitoring port for a security onion vm (mirroring of 3 ports ) and the other for traffic on lan and vlans (vlans are on subinterfaces)
The server 2 is not here yet (i wish minisforum dare to send it but for now they prefer delivering to amazon than their customers) but it will be a proxmox server and i will probably dedicate interfaces for specific usage.
The reason i use lacp is for the router. I have more vlans than interfaces available. So i use 1 interface for lan and a lacp on 2 interfaces for the vlans. It works well like that.
My connection to the isp is 2G/750M that's why i'm looking for 2,5G.
Other devices connected on the switch are not fast (ups, rpi, kvm, ap)
Given your answer i'll probably stick with 2 switches. I changed my network 2 years ago and the unifi 48 poe is far too big for my setup and has only 2 sfp+ ports that's why i added a 8xsfp+ switch.
So if i wish to stay with unifi i probably need an agregation switch and a 16/24 2,5G ports with poe. Downside is with unifi you can't monitor 3ports at a time.
The dell 2224PX-ON would be perfect but hard to find in europe at reasonable price.

Unfortunately there's not a single switch I'm aware of that fits your requirements. I also want a wide mix of features in one device but never could scale down my setup to make that work!

This may be out of your price range at ~999USD (I paid $860 on US Amazon), but the Mikrotik CRS510-8XS-2XQ-IN has just filled a gap for me in Unifi's lineup. I needed a compact-ish switch with at least 8 SFP28 ports and it more than fit the bill. It rocks 8x SFP28 interfaces (1/10/25Gbps) as well as 2x QSFP28 interfaces that can be broken out with a DAC into 4x SFP28 interfaces. It doesn't provide PoE and wasting an SFP28 port on lower speed clients isn't terribly wise, so I need my other switches to handle that. My plan is to take one of the QSFP28 interfaces and break it out into 4x 10Gbps links to my router and 3 access layer switches (all Unifi).
