You run a single network switch for a rack full of drives to the brim?

You run a single network switch for a rack full of drives to the brim?
- jauer 6y agoSure. A single rack is a common failure domain so you make sure to replicate across racks. E.g. Dunno about anyone else, but Facebook racks (generally) have a single switch.
- dilyevsky 6y agoThat seems rather unnecessary risk. Sure you stripe across the racks but another tor switch in mlag configuration is a minuscule expense compared to the costs involved here
- jedberg 6y agoYou could easily run two switches, there would be enough room. But normally yes, I'd run one switch per rack. Switch failure is pretty rare, and when it does happen it's pretty easy to switch it out for a spare.
