 matthewcroughan @fosdem | so I just put a 10G in one of the SFPs and get 3 10G SFP+ out | 10:05:53 |
| matthewcroughan @fosdem | I would really enjoy something with some more SFP ports | 10:06:03 |
 K900 | Well you're still bottlenecked by the upstream | 10:06:53 |
| matthewcroughan @fosdem | WDYM? | 10:07:04 |
| K900 | It's not like it can give you free bandwidth | 10:07:07 |
 uep | sfp ports, not sfp+ ports | 10:07:28 |

| K900 | In reply to @matthewcroughan:defenestrate.it
WDYM? I mean that you can't saturate the three downlinks with one uplink | 10:08:14 |
| uep | protip.. for all mikrotik products, look at the "block diagram" link | 10:12:41 |
| uep | that will show you the difference between the CRS304 and CRS305 models for example | 10:14:24 |
| uep | (in the 305, the 1g port is also on the switch chip, in the 304 it's via cpu) | 10:14:58 |
| uep | * protip.. for all mikrotik products, look at the "block diagram" link (in the support & downloads section) | 10:15:54 |
| matthewcroughan @fosdem | I guess I'll have two though | 10:18:45 |
| matthewcroughan @fosdem | since the bpi-r4 has tw | 10:18:47 |
| matthewcroughan @fosdem | * since the bpi-r4 has two | 10:18:49 |
| K900 | Then you'll just have two up ports and two down ports | 10:23:23 |
| K900 | And at that point why have a switch | 10:23:27 |
| uep | https://mikrotik.com/product/crs309_1g_8s_in in case you meant sfp+ ports after all.. this is the same as the 305 with 8 sfp+ (and a few nicer switch chip features for additional hw offload of l3 nat and fw) | 10:28:33 |
| uep | (I like this one because it's still passive cooling despite all that capacity, though you need to be careful about hot sfps) | 10:30:57 |
| matthewcroughan @fosdem | Do you think it'll run FOSS one day? | 10:34:32 |
| matthewcroughan @fosdem | "Cloud Router Switch" | 10:34:47 |
| matthewcroughan @fosdem | 🙈 | 10:34:51 |
| uep | not readily. it's a linux kernel but mikrotik has opinions about what that actually means, and of course all the interesting stuff for a device like this is the control plane for the switch chip | 10:39:43 |
| uep | Mikrotik do one thing really well, though, and that's somehow have iike a hundred different products with every permutation of chip and cpu, that all work on the same software release and are supported for a very long time | 10:40:54 |
| matthewcroughan @fosdem | I'm sadly just not interested unless it runs a kernel and software I can compile | 10:41:24 |
| matthewcroughan @fosdem | I don't give in to anything else, to give in for a managed switch would just be embarassing | 10:41:47 |
| matthewcroughan @fosdem | it's clearly good hardware | 10:42:08 |
| uep | yeah, valid.. i gave in on that point a long time ago when the alternative was cisco or hp | 10:43:55 |
| matthewcroughan @fosdem | Yeah, I don't see the point in giving in since I'm not doing some for-profit thing | 10:44:19 |
| matthewcroughan @fosdem | this is just for a hackspace network | 10:44:23 |
