Replication Solutions Supported by Open-E DSS
Open-E DSS supports three different types of file based Data (File) Replication
• Asynchronous Data (File) Replication within the system • Asynchronous Data (File) Replication over a LAN • Asynchronous Data (File) Replication over a WAN
Additionally, DSS Supports two types of block based Volume Replication,
• Synchronous Volume Replication over a LAN for NAS, iSCSI and Fibre Channel appliances, • Synchronous Volume Replication over a WAN for NAS, iSCSI and Fibre Channel appliances,

Asynchronous Data (File) Replication within the system Asynchronous Data (File) Replication over a LAN Asynchronous Data (File) Replication over a WAN
Open-E Data (File) Replication enables asynchronous file and folder copy from one storage system to another for maximum data availability.
• With Asynchronous Replication a point-in-time snapshot copy of data on the source is made and copied to the target storage system. • For maximum flexibility, you can run a data replication task in two directions: one system can be both a source and a destination at the same time, allowing cross data backups on several systems. Replication can be used for disaster recovery or disk-to-disk backup.

Asynchronous Data (File) Replication within the System
REPLICATION BETWEEN TWO RAID ARRAYS WITHIN ONE SYSTEM
Recommended Resources
• Key Hardware
x86 compatible RAID Controller 1 RAID Controller 2 HDD‘s Network Interface Cards
• Software
Open-E DSS
Benefits
• Data redundancy over RAID Array • Local data availability • Low cost solution • In case of complete system failure data will be lost or inaccessible
www.open-e.com 6
Disadvantages
Asynchronous Data (File) Replication within the System
• Data is written and read on Array 1 • Data is periodically replicated to Array 2

Asynchronous Data (File) Replication within the System
• In the case of a raid array or disk drive error on Raid Array 1, the server will send an e-mail notification to the administrator and/or users • The administrator then switches from Array 1 to Array 2

Synchronous Volume Replication over a LAN Synchronous Volume Replication over a WAN
Volume Replication (synchronous) over LAN or WAN is block based and supports iSCSI, FC and NAS logical volumes. It provides data availability in case the source system is offline due to a disaster. The destination system will have the replicated data from the source server.
