can anyone give me a compelling reason not to get a Brocade ICX6430-24 to replace my Catalyst 3750G-24TS-S, given the power supply in it is slowly dying?

the brocade is only an L2 switch rather than an L3 like the catalyst, but I can account for that

otherwise specs are largely the same, but the Brocade uses 36W max rather than 100+ idling

Okay, here's a potential issue. The 6430 doesn't have any 10Gbps ports, even SFP, which may not be ideal given it's only an L2 switch.
I guess I could do NIC teaming with multiple NICs on the router, or use one per subnet, but..?

As far as ... exploring other possibilities goes, I haven't done it before, so how's link aggregation (ie, LACP) on Linux? Can I expect to actually get the full-ish speed out of a given set of links? It looks like round-robin mode may be optimal, but apparently it can cause issues too.

@izaya we use

bond-mode 802.3ad
bond-xmit-hash-policy layer3+4

which works pretty well on our dedicated servers. We're dual 10G so we've not really stressed performance that hard. Previously in 1G land we certainly got ~80% of 4x1G with a wide variety of destinations.

On our VPS hosts we now make every link a point to point, route with BGP and use ECMP to spread the load between links.

@izaya Ah. Uh.

Yeah that changes the calculus a little.

@izaya how many ports do you need? Would it be a more reasonable solution to buy 10g cards and gige cards and load up an old amd?
Show threadIzzy's Old AccountAug 31, 2023
@nimbius Realistically I probably don't need more than 12 ports, so it'd be *doable* to make a cursed switch out of a normal computer, but it would not be affordable compared to a sane switch.
Show threadCrispy BranzinoAug 31, 2023
@izaya then I guess my only compelling argument is things like vlan trunking and TCP offloads are already features in cheaper consumer switches without big names. Cisco is a power hungry and noisy answer companies choose because they have a financial obligation to their shareholders to select an ecosystem of technology that aligns with their risk management. Or because theyre running carrier brocade stacks for big data.

I just dont see the value in Cisco new or used.

@izaya @nimbius Have you looked into Mikrotik?

@scj643 @izaya @flisk is effectively an expert in mikrotik. Very experienced. Ive always wanted one of their routers but sadly never got one

@scj643 @nimbius they're pretty rare over here, what hardware would you suggest?
Show threadCrispy BranzinoAug 31, 2023
@izaya @scj643 can't go wrong with netgear, but it depends on your needs. 10gig seems opulent for home use, like,maybe for uplinks? My home network is all openvswitch and a crappy Asus router.
Show threadscj643Aug 31, 2023
@nimbius @izaya I forget not everyone needs 10 gig. I have a 16 port 10 gig core switch and 2 24 port gigabit switches with 2 10 gig links.

@izaya i can't, assuming you can afford the brocade

@ellenor2000 $105 isn't too bad.

@izaya grab it, then once you have it, start dissecting your cisco and figuring out why the power doesn't supply

@izaya if you pay €0,62/kWh like is the basic rate in Germany, you'll yeet that old piece of Cisco junk right on #eNay if not the #eWaste recycler in your juristiction...

@kkarhan $0.40/kWh, so less, but it still hurts.

Mostly thinking that getting rid of it will extend the life of the PV system's battery significantly
Show threadKevin Karhan Aug 31, 2023
@izaya *nodds in agreement* it won't hurt and putting it up for sale may allow someone else harvest it for spare parts or use it in lieu of a broken unit...

@kkarhan @izaya who the fuck pays 0,62€/kWh for energy, i pay like half that
Show threadKevin Karhan Aug 31, 2023

@silhouette @izaya people on basic "must offer" utility plans in Germany...

Some even once peaked above €1,00/kWh when a lot of small electricity resellers folded and people were focibly pushed onto these plans...

Show threadsilhouetteAug 31, 2023
@kkarhan @izaya the problem is that those "smaller resellers" are often less than reputable, and the more reputable ones were forced to take those whose reseller folded.

ofc they're not gonna take them under the same conditions as people who have been with them for years, that'd be kind of hard to justify.
another deficit of letting the free market in on basic utilities, they make provider hopping seem cheap when it's really anything but
Show threadKevin Karhan Sep 1, 2023

@silhouette @izaya if it was my decision, all utilities would've been nationalized into cooperatives and regulated strictly.

Same for any Infrastructure.

In return, infrastructure would be paid for in an open access model based off solidarity.

Because that way, economies of scale would kick in and provide everyone with non-discriminatory access...

Not just for electricity or drinking water or sewage but also telephone (mobile and landline) as well as internet (fiber and wireless)...

Show threadKevin Karhan Sep 1, 2023

@silhouette @izaya the latter one is actually the business trategy longterm of my employers: Become the FTTB/FTTH grid provider and ROI the setup of the network over 10-25 years with line rental fees (aka. open access dark fiber & wavelenght multiplex), as they already support all 3 big mobile networks with transit between their towers and their core network.

That's where the money is as, not at the few €€ for some consumer fiber with "up to" speeds...
