  • “SIOS DataKeeper seamlessly supports any storage volume recognized by Windows, and this substantially simplifies operations while enabling us to utilize all of our storage resources,”

    Uri Inbar, IT Director
  • “SIOS DataKeeper gave us an easy way to move our business-critical SAP ERP system to the Microsoft Azure cloud while meeting our stringent SLAs for availability, disaster recovery, and performance.”

    Daniele Bovina, Systems Architect
  • “SIOS easily meets our data replication requirements and minimizes the amount of downtime so that our patients can continue to receive the highest level of care.”

    Scott Livesay, Network Services Team
    Carroll Hospital Center
  • “The SIOS software exceeded our expectations. Implementation and ongoing administration is easy and we have had zero downtime since we implemented our SIOS DataKeeper SANless clusters.”

    Paul Vienneau, Chief Technology Officer
  • We were able to go from testing to production in a matter of days. Ongoing maintenance is also quite simple, which we expect will minimize our operational expenditures associated with high availability and disaster recovery. If it were not for SIOS, we might not have been able to migrate our environment to the cloud.

    Peter Singer, Director of Information Technology
    Chris O'Brian Lifehouse Hospital
  • “Everything just worked. And the cost of three servers and the SIOS solution was less than the cost of one of their old servers.”

    Brian Roth, IT
    Comport Consulting
  • “The SIOS software has allowed us to create a hybrid solution that provides the cost savings of running on-premises and the reliability and flexibility of running in the cloud. Because we know that if there is a website outage, it will failover automatically, our IT team can now focus their attention on other priorities to strengthen our business.”

    Russell Born, Senior Network Infrastructure Administrator
  • “By enabling us to use a clustering configuration in the cloud in the same way we would in a physical environment, the SIOS DataKeeper software made it possible for us to migrate to AWS without sacrificing application protection or changing the configuration of our existing system at all.”

    Manabu Tsukishima, IT Manager
    Gulliver International
  • “The SIOS DataKeeper Cluster Edition software is a good technology for a company that is growing rapidly. It is easy to use and eliminates the need to buy unnecessary SAN hardware or redundant switches.”

    Edward Schwartz, CIO
    Mavis Discount Tire
  • Even if a problem occurs, LifeKeeper automatically fails over from the primary server node to a secondary node in an instant, and operation continues without any noticeable delays for the users. It saves IT time and eliminates service interruption for customers.

    Hiromasa Tsuboshima, Manager, Business IT Department, Global IT Division
    Mitsubishi Motors
  • We have been using SIOS DataKeeper for several years now, and it has proven to be the most rock-solid piece of software we have. It just works.

    Chad Works, Senior Director of Infrastructure and Security
  • With any clustering technology, you need to be wary of what you’re doing to avoid having failover fail. But with SIOS DataKeeper, the system pretty much just manages and maintains itself…It just works!

    Craig Hannagan, Project Manager
  • “When moving to the new architecture S/4HANA and if clustering is required, we will implement SIOS DataKeeper because we trust it.”

    Akihiko Kobayashi, Akihiko Kobayashi, a System Representative
    Toyo Gosei Ltd.
  • “We recommended SIOS DataKeeper software because it was the only solution that could enable our client to move from a production environment to a fully supported Windows Server Failover Cluster – and to do so without disruption to business operations that rely on SQL Server.”

    Kendal Van Dyke, Principal Consultant
  • “We have tested our file server with both DFS replication and AlwaysOn technology. Neither delivered an automated disaster recovery solution to match SIOS DataKeeper, which fully addresses our DR requirements.”

    Maurits van de Lande, CEO
    Van de Lande
