slide 22 states that the cost is 1 CHF/TB/month (on 10+2 erasure coded disks), though it would be interesting to do a breakdown of costs (development, hardware, maintenance, datacenter, servicing, management, etc..)
- pclmulqdq 2y ago1 CHF/TB/month is a bit expensive for storage at that scale, so it would definitely be interesting to see what they're spending the money on and what they are (and aren't) counting in that price.

- rob_c 2y agoTape backup, accessibility, networking, availability... At 1CHF/TB that's a lot better than my local university still charging >100x that for such services internally
- pclmulqdq 2y agoEconomies of scale in storage are significant. Also, I don't know why you put up with your university charging 100x that when you can store things on AWS for $5-10/TB/month (or less). That comes with all the guarantees (or more) of durability and availability you get from the university.
- lnauta 2y agoDon't forget bandwidth costs at this scale are significant to say the least.
- pclmulqdq 2y agoI assume most of that exabyte is stored in 2-3 datacenters, in which case the bandwidth cost is actually relatively small. Downloading it would cost a fortune (or take an eternity), but if it stays in the datacenter (or stays in AWS), bandwidth is cheap.
