Introduction

SIOS DataKeeper Cluster Edition is a highly optimized host-based replication solution which integrates seamlessly with Windows Server Failover Clustering. Features of Windows Server Failover Clustering such as cross-subnet failover and tunable heartbeat parameters make it easy for administrators to deploy geographically dispersed clusters. SIOS DataKeeper provides the data replication mechanism which extends both versions of Windows Clustering, allowing administrators to take advantage of these advanced features to support non-shared disk high availability configurations.

Once SIOS DataKeeper Cluster Edition is installed, a new storage class resource type called DataKeeper Volume is available. This new SIOS DataKeeper Volume resource can be used in place of the traditional Physical Disk shared storage resource to enable geographically dispersed clusters, also known as multi-site clusters.

DataKeeper Cluster Edition Requirements

*Important: When restoring a DataKeeper volume or recovering/restoring a new system(s) and its related DataKeeper Volumes from a backup or snapshot, it is required that a FULL RESYNC be forced via the DK GUI on all restored DataKeeper volumes. This must be done to ensure an identical replica of the data will reside on the Source(s) and Target(s).
The steps for forcing a FULL RESYNC are as follows:
• Launching the DataKeeper GUI
• Selecting the mirror(s)
• Choose Break Mirror
  ◦After the mirror(s) status reflects Broken, select Resync Mirror (this is a FULL Resync).

*Important: SIOS Technology Corp. recommends that users use Domain accounts that have local Admin privileges on all servers running DataKeeper. If you are using Local accounts, the username and passwords must match on all servers running DataKeeper. This recommendation is for all editions and all platforms.

*Operating system rolling upgrades are NOT supported.

DataKeeper System Requirements

*Note: Memory and CPU usage will increase based on the number, size, and write activity of the mirrors.

Local Security Policy Requirement

If your Windows servers are not in a domain and you are going to run the DataKeeper Service as the local system account, the Local Security policy setting “Network Access: Let Everyone permissions apply to anonymous users” must be enabled.

Known Issues

Missing Job Information warning displayed during mirror creation or deletion

During job creation, the warning “This computer is missing SIOS DataKeeper Job information for the following target volume(s): <vol>” might be displayed in the GUI briefly. The warning will go away after a few seconds. This is a transient condition that can occur during mirror creation and deletion, and does not indicate an error.

Windows 2016

• Occasional job creation failure
