High Availability and Disaster Recovery Solutions for Physical and Virtual Servers
No Need to Learn a New Availability Solution for Every Environment You Manage
SIOS clustering solutions are unique in the breadth of applications, operating systems and infrastructure environments supported, giving you a single solution to handle your high availability needs. SIOS software protects applications like SAP and databases such as SQL Server, Oracle, and many others running in SAN-based, shared storage configurations or SANless, local data storage configurations. SIOS solutions enable high availability and disaster recovery protection for Windows or Linux applications operating in any combination of physical, virtual, cloud, or hybrid cloud infrastructures.
Flexible, powerful availability solutions, that are easy to learn and easy to deploy across all of these environments. That’s why we call them, Clusters Your Way.
High Availability Clusters in Environments Where SANs are Impractical or Impossible
SIOS SANless clustering software lets you build a Windows or Linux cluster that uses only local storage – eliminating the cost and single point of failure risk of a traditional SAN. Real-time replication keeps local storage on primary and standby machines synchronized, giving applications immediate access to current data even in the event of a failover. You get high availability and disaster protection in a single, cost-efficient solution.
SIOS lets you build a cluster with your choice of industry-standard hardware and a wide array of storage devices, including direct attached SCSI, iSCSI, Fibre Channel and more. Unlike SAN solutions, SIOS cluster software lets you mix hardware configurations at the source and target for maximum flexibility with no vendor lock-in.
High Availability protection and performance
SIOS SANless clusters provide high performance, low latency block level replication with minimal overhead. The extraordinarily high efficiency of SIOS clustering replication technology makes it possible to use high-speed storage solutions such as flash-based PCIe and SSD for high availability, disaster protection, and performance in a single solution at a fraction of the cost of a SAN.
Advanced SAN-based Cluster Protection
SIOS SAN-based server cluster software lets you build a cluster to protect your business-critical Windows or Linux applications and data from downtime and disasters. This powerful software makes clusters easy to use and easy to own.
SIOS delivers proven cluster solutions for SAN-based environments that provide tightly integrated application monitoring and failover for all layers of the system stack; including server, storage, network, database and/or application. Any type of shared storage can be used (Fibre Channel SAN, iSCSI, NAS) for maximum configuration flexibility.
In the event of a failure in the system stack, SIOS software automatically attempts to restart the application. If the restart fails, SIOS moves operations to the standby server for fast, seamless failover.
Our user-friendly interface lets you configure your SIOS cluster in minutes and makes ongoing monitoring and management easy.
