So, I'm going to do something a bit different today.

Unlike 90% of the random posts showing peoples racks- I'm going to show you the BACK of the rack too.

Enjoy. There is quite a bit of cable-maintenance in play here. If- you look at the switches in the front- notice the 10G switch, has all 8 ports populated. Notice- the 24 port switch, only has 6 ports not in use. Notice the 100G switch, has all 4 ports populated (the last one has a 4x10G breakout).

That is 35 total cables/fiber runs.

The magic is- when you see the pictures INSIDE of the rack, and at the rear of the rack- you don't see ethernet/fiber everywhere.

You do- see SAS cables, and 100G DACs, but, those are a bit rigid, and don't like being maniuplated too much.

Another note- The SFFs & r730XD have redundant networking- The primary link is the 100G switch, with a failover link back to the 10G switch. Either of those switches can be brough offline.

Application storage is ceph- which is hosted on the SFFs, and the r730XD. The SFFs leverage SAS SSDs inside of the 2.5" enclosure. The r730XD has a dozen or so M.2 drives inside of it.

Enjoy!
