10 Gigabit home networking

Yes I know it's mostly absurd / just for bragging rights, but the Microtik CRS305-1G-4S+IN boxes made it possible for not too crazy an expenditure.  These have one gigabit copper port plus 4 SFP+ sockets for 10 gigabit modules - I'm using a mixture of 10Gtek 10GBase-TX modules and DAC cables to my Synology / Supermicro box which have SPF+ connections themselves.

I have a pair of Synology NAS (one of which is running VMs within via KVM), plus a single ESXi server and a Mac with 10 gig, plus all the usual TVs and home Internet devices.  My office is in the garage, a 100M run from the wiring closet (alright coat closet, but also where all the Cat 5 runs go to) in the house.  What I wanted the flexibility to do was site one or both Synologies in the house while retaining 10 gig access to the bigger one (actual transfer tops out at just over 2 gig) and not impacting other services over the wire.  I ran a Cat 7 cable which I knew would need to be right at 100M so purchased a 125M one - the run ended up being 110M.  I spent a lot of effort finding copper SFP+ that stated they would run at 5 and 2.5 in addition to 10, expecting to need the option and 2.5 or 5 be all that was reliable (and more than sufficient for me anyhow).  In the end it works fine at 10 gig, no errors.
