Many companies rely on key applications using SQL Server for their important business functions. Downtime can be devastating. These environments require high availability protection to prevent lost revenue, lost productivity and lost customer satisfaction resulting from application downtime.
Clusters for SQL Server High Availability without Shared Storage On-Premises and in the Cloud
SIOS software is a low cost, highly flexible, and easy to use solution that enables high availability and disaster recovery protection for SQL Server applications operating in any combination of physical, virtual, cloud, or hybrid cloud infrastructures. High availability clustering typically requires costly and complex shared storage SANs. With SIOS SANless clusters, there’s no need for SAN storage to create an enterprise-class high availability cluster.
SIOS DataKeeper Cluster Edition Protects SQL Server
Microsoft Windows Server Failover Clustering (WSFC) is commonly used to provide high availability for applications using SQL Server. It implements full coordination of redundant computing resources and automatically manages the recovery of SQL Server operations and data on a standby node in the event of server or application failure. But WSFC requires expensive SAN hardware to assure data redundancy and requires complex setup and deployment. And if you want to run your SQL Server application in the cloud with the same high availability assurances, there’s no SAN available and no fully supported way to do that between cloud regions or availability zones.
SIOS DataKeeper Cluster Edition is a software add-on that integrates simply and seamlessly with Windows Server Failover Clustering to add performance-optimized host-based synchronous or asynchronous replication. SIOS DataKeeper Cluster Edition allows you to easily create a SANless WSFC to achieve high availability and disaster recovery for your SQL Server applications operating in the cloud, in virtualized environments such as VMware, or on physical servers using only local storage. You can build hybrid cloud configurations for disaster recovery protection between an on-premises data center and the cloud.
SIOS DataKeeper Cluster Edition software is fully certified by Microsoft and operates with Enterprise-Class availability in any configuration across cloud regions and zones.
Protecting SQL Server in Cloud and Hybrid Cloud Across Zones and Regions
SIOS DataKeeper lets you run your business-critical applications in a flexible, scalable cloud environment, such as Amazon Web Services (AWS), Azure, and Google Cloud Platform without sacrificing performance, high availability or disaster protection. SIOS DataKeeper is available in the AWS Marketplace and the only Azure certified high availability software for WSFC offered in the Azure Marketplace.
Scale Out File Server (SOFS) and Storage Spaces Direct (S2D), two technologies offered in Microsoft Windows for sharing disks, can’t be used in a cluster for sharing disks across cloud regions and availability zones. This limits your configuration to one data center (availability zone) and if there is a failure there, you can lose access to SQL Server application services.
In contrast, SIOS DataKeeper Cluster Edition fully simulates clustered shared storage and is capable of providing fully certified high availability cluster protection across cloud regions and availability zones – giving you significantly greater protection from a broad class of failures.
Compare SQL Server Cluster Options for High Availability
For SQL Server clustering, a common choice of availability is Microsoft Always On Availability Groups and Always on Failover Clusters. SIOS DataKeeper provides a number of key benefits to achieve higher availability and more comprehensive data protection.
SIOS Protection Suite – Protecting Microsoft SQL on Linux
The SIOS Protection Suite for Linux offers integrated data replication, high availability clustering and disaster recovery solutions supporting SQL Server to provide fault-resilient protection for the most demanding enterprise deployments. In environments running SQL Server, SIOS Protection Suite for Linux monitors application stack components not protected by SQL Server itself, such as applications, servers, and network connections.
As of July 9, 2019, SQL Server 2008 will reach End of Support, which means the end of regular Security Updates, leaving this critical infrastructure, and your business, vulnerable. If you’re choosing to move your SQL Server 2008 instances to Azure to take advantage of Microsoft’s free Extended Security Update program, you will need solutions to maintain your availability SLAs in Azure. SIOS provides a unique software solution that can help you achieve full high availability and disaster recovery for your SQL Server 2008 applications running in Azure. Learn more.
