Inside Harbour MSP's datacentre: photos

Talkback

• This datacentre looks positively ancient compared to what most modern ones are doing with cold air containment to bring down power consumption. It doesn't take much and even facebook (see link below) has been retrofitting older open plan DCs with cold air containment through a variety of methods. They saved US$230,000 from their annual power bill. Google has been known to use old freezer room plastic curtains, in the style of that at a butcher, at one of the older datacentres they used to reduce cost.

• hmmm
  Nothing too special happening there.. Looks OK but just a typical DC.
  What was it I read 30TB per disk on the old NetApp FAS3040. I don't think so.. OR should it have read that by using NetApps deduplication technologies each 300GB hard disk can store 30TB??? Still a bit far fetched.

• I was thinking the same thing as markzz.
  
  From that I can gather the FAS3040 had a maximum capacity of 336TB which would mean it would only need 12 disks at 30TB to reach maximum capacity.
  
  Looking at the photos we have 14 disks per array so we would need less that one array to fit out the storage server.
  
  Taking this further it looks like we have 3 unit arrays so we would have between 4.2 and 5.8 Petabytes of storage if the rack height was somewhere between a relatively small 36 unit and massive 48 unit rack given the storage servers use of 6 units.
  
  However if we considered each array to be 30TB then we would need ~12 arrays to reach maximum capacity and therefore 12*3+6 units in a 42U rack. Sounds more plausible if you ask me.
