Real-Time Data Replication Over DSL

Data replication over the Wide Area Network (WAN) is not a new concept, but like most business practices being evaluated in difficult economic times, it is finding new life in its application and delivery method. Traditionally, WAN Data Replication was the domain of point-to-point Fiber connections from one Data Center to another; or at best, from a Data Center to a company headquarters. Due to this high-bandwidth, high capital cost requirement, most businesses and IT managers did not have the luxury to implement such a crucial business process into daily operations. But that has now changed. The SmarttNet Arista Service is a bonded DSL solution capable of providing the throughput and uptime to replicate data from multiple locations. Not only that, it can be deployed at a fraction of the capital expenditure cost and time delay typically associated in rolling out high bandwidth solutions. Arista relies on multiple bonded DSL lines connected ??? end-to-end ??? on Cisco equipment, and running without proxies, caching, or aggregation. Data generated by various Servers and Devices is sent through a private network or the Internet in real time. Data Replication can now be implemented at multiple locations providing geographic redundancy for IT managers. Some of the greatest concerns when dealing with DSL based services are the reliability of such a service and its throughput capability. Due to the network architecture and device configuration, Arista is capable of shutting down one or more of its bonded DSL links while repairs are completed on the affected line. The service as a whole can continue operating until the problem is resolved, at which time the faulty line can be reactivated and service may resume as normal. The throughput capability of Arista also caters to data replication. With an asymmetrical configuration expandable up to 24Mbps/4Mbps, Arista can export over 1 Terabyte of replicatable data to any remote location and import over 5 Terabytes of data. Various configurations can be created, ranging from Hybrid Fiber-Arista setups to purely Arista Configurations in order to maximize efficiency and reduce cost of deployment.?? Deployment can be accomplished in under two weeks and service is available to nearly 99% of business addresses. Data integrity is now manageable among remote sites and temporary sites of operations. Business continuity using data replication is no longer part of some far off wish list for future implementation, but a reality that is quickly deployable and technologically robust.
