SteelEye DataKeeper and DataKeeper Cluster Edition

Highly optimized business continuity solutions forWindows Server 2003 and 2008

If data is the lifeblood of your organization, then you know protecting that asset isthe key to your continued success. No matter how fault tolerant your servers and storage subsystems may be, if you only have a single copy of the most current data, you are at risk of data loss. Catastrophic failures of your storage subsystem due to hardware failure or natural disasters can bring your data centre to its knees.

Backup tapes can only take you so far and native Windows data replication tools are generally application specific, limited in scope and are hard to manage. SteelEye DataKeeper overcomes these issues by providing real-time data replication that can also integrate with Microsoft Windows Server Failover Clustering* to enable multi-site clustering while eliminating the single point of failure that a traditional shared physical disk cluster resource represents.

IT organizations face many challenges in providing users with the most comprehensive and cost-effective disaster recovery and business continuity services. The following table highlights those challenges and how SteelEye DataKeeper can provide the foundation for addressing them to improve productivity and availability for all your Windows Server deployments.

Data Replication Challenges	SteelEye DataKeeper Advantages
Ensuringy our data is available 24x7x365 regardless of the type of failure: storage subsystem, user error, or site loss	Provides continuous real-time host-based block-level replication of data insuring multiple copies of your data is available at all times
Eliminating downtime associated with virtual servers that have been consolidated onto asingle server and storage array	Advanced virtual machine support for Hyper-V, VMware, Microsoft Virtual Server 2005,Citrix XenServer, and other virtualization technologies Replicate data while running within guest virtual machines Replicate entire virtual machines files while running within the Windows hostserver (Hyper-V, VMware Server or Microsoft Virtual Server)
Exceeding Service level agreements while staying within budget	Multi-site clustering provides the highest RPO and RTO available. DataKeeper enables this technology without a large investment in array based replication.
Overcoming bandwidth and latency limitations associated with WAN replication	Optimized for WAN replication 9Levels of Compression WANacceleration provides maximum throughput for high speed networks BandwidthThrottling
Avoiding full resynchronizations of critical data	Incremental synchronization of large database and email repositories
Replicating transactional email and database data	Block based replication ensures that regardless of the data type, replication is fastand efficient
Protecting data using your existing hardware and infrastructure	Does not require the introduction of a new file system - utilizes standardNTSF file system Leverage existing IP networks Storage independent replication Does not require new or matching storage subsystems Utilize existing storage Replicate from SAN to SAN, Local Attached to Local Attached, SAN to Local Attached, etc. Make use of virtualization technology such as VMWare, MS Virtual Server,XenSource, etc. Fraction of the cost of array based replication Does not require the use of hardware based WAN accelerators
Identifying compatible solutions for multiple server and storage vendor environments	Replication works across disparate storage arrays, and with no regard to make or model ofserver or storage, allowing the optimal use of your available resources
Protection for all data - not just specific applications, e.g., SQL log shipping	Works independently from and with no dependencies related to applications beingprotected
Choosing the correct type of replication for your requirements: asynchronous vs.synchronous	Choose between synchronous or asynchronous replication, depending upon your dataprotection requirements
Completing backups within shrinking backup windows	Access to the target system allows backups to complete on the replicated data set,allowing backups to complete without impacting production servers

LifeKeeper Gives Excellent Results

Our configuration means that the application doesn’t notice when SteelEye LifeKeeper fails over Oracle – therefore we get very close to zero downtime.
