ShaoLin Volume Replicator

Features & Benefits

ShaoLin Volume Replicator is an software-based open solution, unlike other proprietary solutions which rely on special volume formats, proprietary volume managers, file system types or hardware. It provides a flexible solution to replicate existing data sets (volumes) of any file system types without modification. In addition, ShaoLin Volume Replicator replicates data between any storage hardware platform, across any standard IP network and over any distance. It utilizes existing infrastructure without the need of using any proprietary hardware, file systems or special volume managers, eliminating vendor-specific storage limitations.

Whether you are motivated by disaster or site failure, the cost and risk of deployment and migration often be the obstacles of implementing a DR plan. Thanks to ShaoLin's advanced stackable storage technology, ShaoLin Volume Replicator provides the easiest installation and painless migration. Users can simply setup ShaoLin Volume Replicator and mirroring existing production volumes to alternate sites instantly without taking the system offline. No data migration, file system formatting, disks repartitioning or any destructive actions is needed when deploying the solution. In addition, ShaoLin Volume Replicator runs on most of the latest Linux distributions and kernels without the need of patching or customizing kernel configurations.

With our cutting edge technology, ShaoLin Volume Replicator supports data replication to infinite number of secondary sites over any distance - across campus or across the globe. It ably handles one-to-one, one-to-many and many-to-one data replication configurations. ShaoLin Volume Replicator also features the multi-path load balanced data transmission which allows high utilization of network bandwidth with multiple highly available communication channels. The product delivers limitless scalability, high availability and resilience to accommodate the widest range of business needs.

Thanks to ShaoLin's unique high performance and kernel-based Kypertec Compression Engine, ShaoLin Volume Replicator makes efficient use of network resources and provides maximum performance by compressing data blocks for replication over long distances. This lowers network bandwidth requirement and enables higher throughput in a narrow bandwidth. The seamless integration of Linux buffer cache and ShaoLin Volume Replicator also minimizes delay and maximizes bandwidth utilization by using a fully paralleled multi-threaded algorithm for data transmission.

Since ShaoLin Volume Replicator is a block level virtual volume device driver, it only replicates the data blocks that actually changes instead of the complete file or volume to keep network traffic to a minimum. In case of network outages and failures between the replicated sites, the changes of volume will be remembered and they will be resynchronized upon network reconnection. In the event of a migration from a primary to a secondary site, ShaoLin Volume Replicator provides rapid resynchronization that failover and failback can occur under all shutdown scenarios without resending entire data sets over the network.

ShaoLin Volume Replicator makes both synchronous and asynchronous modes of replication available for different business requirements and network conditions. Synchronous replication does not allow the secondary sites to get behind or lag, thus eliminating the threat of any data loss. With asynchronous data replication, ShaoLin Volume Replicator guarantees data consistency within and among volumes to deliver uncompromised data integrity at secondary locations. Application performance will not be sacrificed if replication is over a narrow bandwidth or high latency network over long distances. ShaoLin Volume Replicator also can switch from synchronous to asynchronous mode on the fly to minimize downtime when network failure occurred.

ShaoLin Volume Replicator offers encryption capabilities for enhancing data security. Data can be encrypted in the volume and as well as in the replication stream. With encryption done in the data phrase, replication stream can be protected with using normal TCP/IP transmission and does not require high overhead VPN infrastructures. Remote replicated storage systems can be hosted in unmanned off-site area or anonymous data centers as backup sites which only receive encrypted data from the primary site. Furthermore, the ultra fast variable key length from 32-bit to 448-bit blowfish volume encryption featured in ShaoLin Volume Replicator extends the security capability of just a disaster recovery solution but an ideal and flexible data protection solution.

ShaoLin Volume Replicator is a driver that propagates a virtual volume which works like a standard storage volume. This allows data written by any applications and even database systems to be replicated. ShaoLin Volume Replicator fully supports all types of applications and database management system, including Oracle, Sybase, DB2, MySQL, etc.
