  • Alternate Sites

    • Using additional servers, storage, replication technology and private dedicated circuits between your facility and our data center we can fashion a whole array of failover solutions


    • Declining hardware, storage and telecommunications costs make high-end disaster recovery an option even for small companies


    • Online Tech can use its multiple data centers to offer co-location customers hot-site failover


    • Online Tech uses a “DR quadrant” with level of severity on the Y axis and time to recovery on the X axis. Where on that quadrant do you want to be?


  • Hot-Site

    • Redundant equipment in Online Tech’s data center with high speed (fiber) telecommunications to replicate the data in near real-time


    • High speed (e.g. optical) circuits between your production facility and one of Online Tech’s DR facilities allows for near real-time replication of data and program


    • During an outage, traffic to the production system is automatically routed to the hot-site for continued operation


    • Allows for extremely rapid failover from very severe scenarios


  • Warm-Site

    • Place equipment in Online Tech’s data center that is similar to your production equipment.


    • Connect them with high speed telecommunications to replicate the data in batch (for example, nightly)


    • During an outage, servers at DR site are started and loaded with the lastest dataset. Traffic is routed to the DR site.


    • Removes rebuilding server and restoring data from the “critical path” of returning to operation


  • Cold-Site

    • Spare servers, storage and backup data are on hand but not kept running.


    • Restoration begins by powering up servers, updating software and restoring data from backup


    • Removes “waiting for hardware” from the critical path. During an emergency it can be very difficult to get hardware


  • What's right for you?

    • How much down time can you afford? A Hot Site can provide almost 100% up time in even the most extreme disasters.


    • What is your budget? Hot sites are exponentially more expensive than warm sites or cold sites.
