Thus, a storage system has been implemented in Moscow in which one half is located in one Tier 3 Data Center and the second half — at a distance of 6,2 miles far in another Tier 3 Data Center with both halves operates synchronously as a single structure. In case of any failure in one of the Data Centers (power failure, failure of any part of the storage system, failure of controllers, disks, communication channels between Data Centers) your data will remain available (RPOi = 0, RTOii = 10 minutes), you won't lose any transaction.
