add.NON-STOP enables users to maintain a continuous connection with their IT system – even in case of failure, they will never be aware that a backup location has been activated. add.NON-STOP ensures switching between the primary and backup IT environments (physical or virtual) in a few seconds, and allows the user to access the data even during IT system failures.
The increasing tendency of using IT systems more efficiently and the reduction of operation costs encourage the companies to use server consolidation. However, this transition to virtual environments requires planned system downtime, during which users will not be able to perform their jobs. Consolidated servers function as hosts for many virtual servers. In case one of these servers fails, several dependant servers will also fail, and this can be even worse than a single physical server failure. An unexpected consolidated server failure may bring about serious IT operation problems, i.e. loss or destruction of important data.
In order to ensure full usage of virtual environment capabilities, companies must find a way to safely transfer physical servers to virtual environments and protect them with solutions ensuring high availability. By using equivalent methods of ensuring high availability to “physical-to-physical” environments, and in combination with virtual technologies like VMWARE ESX Server or Microsoft Virtual Server, add.NON-STOP guarantees high availability of virtual environments. The add.NON-STOP family of tools supports all Windows® and Linux product types, e.g.: Microsoft® Exchange, SharePoint®, SQL Server, File Server, IIS, RIM BlackBerry®, IBM® Lotus® Domino® and Oracle.
add.NON-STOP offers two unique functionalities:
add.NON-STOP with Heartbeat technology
replication of data from the active server to the passive server through LAN or WAN.
add.NON-STOP SCOPE Professional
analysis of the functioning of servers, applications, IT services and performance prior to the implementation of high availability and during high-availability functioning.
add.NON-STOP is an ideal tool for transitioning from old to new systems, IT environment consolidation, upgrades and IT system maintenance.
add.NON-STOP helps you use the advantages of virtual environments, while ensuring high availability and continuous data synchronization.
