Introduction
SteelEye DataKeeper Cluster Edition is a highly optimized host-based replication solution which integrates
seamlessly with Windows Server 2012, Windows Server 2008/2008 R2/2008 R2 SP1 Failover Clustering aswell as Windows Server 2003 Cluster Service. 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. SteelEye 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 SteelEye DataKeeper Cluster Edition is installed, a new storage class resource type called DataKeeper
Volume is available. This new SteelEye 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-siteclusters.

New Features of SteelEye DataKeeper Cluster Edition v7

FeatureDescription
DataKeeper Cluster Edition now supports the ability to create point intime copies of replicated target volumes without impacting operations
such as switchovers and failovers allowing access to data on a standby
cluster node to perform tasks such as:
1. Enabling SQLServer Reporting on underutilized target systems
2. Allowing backups to be run on secondary systems, offloading
the IO and CPU demand from the primary system
3. Allowing offloading of Extract, Transform and Load (ETL) orother time-consuming processes

Target Snapshot

This allows your data to be used on an otherwise idle target node
without negatively impacting the performance of the source, offloading
work from the source by using the CPU and IO bandwitdh of the target
server.
DataKeeper target snapshot is currently supported in non-shared (1x1,1x1x1, 2x1) environments using Windows 2008 R2 and Windows
Server 2012.
DataKeeper Cluster Edition now supports Internet Protocol Version 6(IPv6). Due to this change, IPv4 and IPv6 subnet addresses use CIDR
notation.

IPv6

Add property DiskRunChkDsk to DKCE volumes to avoid validation
errors. This is a change in behavior to comply with Microsoft recomAutomatic Check Disk (chkdsk)
mendations. Read the considerations in the upgrade section to understand the implications of this change.

Server 2012 now allows customers to build iSCSI Target clusters using
replicated storage with DataKeeper Cluster Edition. In addition to traditional use cases for iSCSI Target software, iSCSI Target clusters canalso be used in CSV configurations allowing for the possibility of using
DataKeeper Cluster Edition to replicate Scale Out File Server workloads as well as Hyper-V VMs deployed on CSVs hosted on the iSCSITarget cluster.

lThe Windows Failover Cluster environment must be installed and configured prior to installing theSteelEye DataKeeper Cluster Edition software up to the point of creating your first cluster resource.
Follow Microsoft best practices for deploying geographically dispersed clusters, including changing thequorum mode majority node set with a file share witness. If the basic Windows cluster is notconfigured prior to installing DataKeeper Cluster Edition, a repair installation of DataKeeper
Cluster Edition is necessary before you are able to create a DataKeeper cluster resource.

Requirements for Windows 2008
While installing SteelEye DataKeeper Cluster Edition on Windows 2008, a dialog box will appear asking
whether the installer should make the system configuration changes described below. If the installer is notallowed to make these changes, they will need to be made manually after installation is complete.
