makiatto is a 10Gbps switch which will handle traffic for high bandwidth devices. Right now that's the NAS (fenny), and will include my workstation once I get 10G connectivity to that room as well. makiatto is connected to sabrina via a 2x10G LAG, though for practical purposes there's nothing connected to sabrina that will need that much bandwidth, even in aggregate.

makiatto is a Mikrotik CRS312-4C+8XG-RM:

The CRS312 has the option to run SwitchOS, but I'm sticking with RouterOS because it integrates well with everything else I'm using.

Features and uses

8x 10G RJ45 ports
4x 10G RJ45-or-SFP+ combo ports
1x 100M mgmt port attached directly to the CPU

Hardware

Marvell 98DX8212 switch chip, which governs what features you can lean on and how they're handled. Mikrotik has notes about L3 Hardware Offload: https://help.mikrotik.com/docs/spaces/ROS/pages/62390319/L3+Hardware+Offloading#L3HardwareOffloading-CRS3xx%2CCRS5xx%3ASwitchDX8000andDX4000Series

And some notes about the switch chips specifically in the higher end models: https://help.mikrotik.com/docs/spaces/ROS/pages/30474317/CRS3xx+CRS5xx+CCR2116+CCR2216+switch+chip+features#CRS3xx,CRS5xx,CCR2116,CCR2216switchchipfeatures-Models

Of particular interest to us is hardware offloading of bridge VLAN filtering (with some listed caveats), which means performance won't dip even if I need to do some VLAN faffery.

Preparation

Some notes from when I received it:

Fun ideas

Like the CRS320, the CRS312 also has lots of free real estate on the front. Why not put a custom waifu decal on it? See sabrina for context.
