- mgbmtl 6y agoOther random bits: SBG-2 was an older generation datacenter, had ventilation issues? They have 4 other datacenters who have a similar design. Others, including SBG-3, have newer designs. They're building 2500 servers per week. For the offline buildings that are not destroyed, they have to rebuild the electrical distribution and network. It was not clear if they are also moving servers physically.
- verytrivial 6y agoI read his description and literal hand waving as saying that for efficiency reasons, in 2011 they were sort of build like how you'd build a camp fire: convective airflow drawn through and out the top.
- fanf2 6y agoRight, this is the OVH “tower” data center design. Here’s a google maps link to the OVH Strasbourg site https://goo.gl/maps/rQjir8byKNwMDZrm9 https://goo.gl/maps/rQjir8byKNwMDZrm9 with (from south to north) SBG1 (a collection of shipping containers), SBG2 (a figure 8 shape), and SBG3 (a box). The idea of the tower design is to take ambient air in through the outside walls, through I think just one row of servers, then into a central void where convection pulls the air out.

- jeffbee 6y agoThis is taking to extremes my maxim that UPSes cause more outages than they prevent.
- teh_klev 6y agoIt's always the bloody UPS after "maintenance" :) Back when I worked in hosting we'd get an email from this particular DC's NOC about either "UPS Maintenance" or generator testing. Our hearts would sink because, during one particular eighteen month period, there was a 50/50 chance our suite would go dark afterwards.
