In Moscow, we implemented a storage system in which one half is located in a Tier3 data centre, and the other half is 10 km away in another Tier3 data centre, and both sides work synchronously as a single structure. In case of any failure in one of the data centres (power failure, failure of any part of the storage system, failure of controllers, disks, communication channels between the data centres) your data will remain available (RPO i=0, RTO ii=10 minutes), i.e. not a single transaction is lost. SyncCluster от Cloud4Y — это экономически эффективное решение, которое обеспечивает постоянную доступность сервисов и данных для компаний, непрерывность бизнеса в которых является критичной. Мы предлагаем SyncCluster в формате услуги с помесячной оплатой, это позволит нашим клиентам воспользоваться данной услугой без капитальных затрат на покупку оборудования и его техническое содержание.

Resolved problems:

  • power failure;
  • fire:
  • natural disasters;
  • human errors;
  • пinvestigation activities in the data centre.
i RPO (recovery point objective) — acceptable data loss.
ii RTO (recovery time objective) — acceptable recovery time.
