I just bought this the other day to setup a VPN to guard the IPMI interface in a 2U server I could cheaply house in some otherwise unmanaged rackspace. It's a pretty nifty piece of kit, but I still have to get better at understanding RouterOS.

I think the crucial flaw here for the IPMI/BMC access use case is the fact that the card requires the server to be powered on to function. So if you accidentally turn the server off it’s game over for remote access.

Yes, but not a very deep problem in my case since I can order Remote Hands for this very niche scenario. A reboot doesn't let it loose power and that's all this is going to see for the forseeable future.

Looks like these are now in stock at Getic for $160 each. https://www.getic.com/product/mikrotik-ccr2004-1g-2xs-pcie I've bought Mikrotik gear from them before. They ship to the USA.

This is where I got mine, came in last week. Zero issues.

Does it support DPDK for fast packet processing or maybe SR-IOV ?. Given the price tag, I suppose it doesn't, but the documentation is sparse.

Lack of SR-IOV is mentioned in the article.

I dont think you can install your own OS on this, yet? :) , in order to do 25GBPS on ARM, I am sure they are doing some sort of DPDK ( I mean user space networking.). I would love to learn more on how do they achieve 25GBPS on this little arm64.

Almost guarantee that they aren't doing 25GBPS on the arm chip but on the dedicated ASIC.

I know for most of the Mikrotik platforms what gets offloaded to the ASIC and what gets handled by the CPU is a big deal in performance tuning and selecting the correct product for your use case.

I also think they only achieve about 15GBPS on their backplanes of their routers with SFP28, enough to show a benefit over SFP+ but not really full speed.

Today I upgraded RouterOS from 7.10 to 7.12 on a hAP ac3, which went well, and on a CRS, which wiped the entire config, and the cloud backup was not restorable. Trying a subsequent downgrade (so I could perhaps restore the 7.10 cloud backup) soft-bricked the whole thing and I had to fix it with NetInstall. Maybe I will have to start exporting the config to a fucking text file, I guess.

I love RouterOS and have been using it extensively for home and soho. And I absolutely agree: it can bee a pain to set it up. Every little part of it is complicated enough to spend hours on. Setting up networks can take long long hours. But documentation has improved lately and you can also watch their own YouTube channel, which has some useful videos. Also you should try using their forum, which is full of helpful g…

RouterOS really isn't any more difficult to learn than competing NOS like JunOS or IOS-XR, both of which also suffer from much in the way of easy-to-use Getting Started kind of docs for newcomers to high-end networking gear. Having used Juniper gear in my homelab for multiple years before I ever bought a Mikrotik switch our router, the hardest part was figuring out where everything was compared to JunOS.

I'm interested to see how many people saying that RouterOS is difficult to pick up are completely new to managed networking equipment, compared to how many are moving from competing solutions.
