WANdisco Announces New High Availability Disaster Recovery Solution for CVS, Subversion and CVSNT; New WANdisco HADR Product Delivers High Availability, Continuous Real-time Backup, and Automated Disaster Recovery Over a LAN or WAN.PLEASANTON, Calif. -- WANdisco, the world leader in real-time multi-site development solutions, today announced the release of WANdisco HADR HADR High Availability Disaster Recovery (IBM) HADR Humanitarian Assistance and Disaster Relief HADR Hughes Air Defense Radar HADR Highly Ability Disaster Recovery for high availability Also called "RAS" (reliability, availability, serviceability) or "fault resilient," it refers to a multiprocessing system that can quickly recover from a failure. There may be a minute or two of downtime while one system switches over to another, but processing will continue. and disaster recovery. WANdisco HADR leverages WANdisco's active-active replication architecture and self-healing capabilities to provide continuous real-time backup, while making failover and disaster recovery automatic and transparent to both users and administrators. WANdisco HADR is the only solution that captures everything up to the moment of failure, so that no data is lost in the event of a network outage A network outage is an interruption in availability of a system due to the communication failure of the network. Network outages cost money directly to the organisation (for example Banks, Airlines, Online Transaction companies); or cost money indirectly to customers ISP, or server crash. In addition, WANdisco HADR restores user access immediately after a server failure. No other solution for high availability and disaster recovery can make these claims. In addition, WANdisco HADR delivers these capabilities over a LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. , or a WAN. WANdisco HADR: --Makes recovery fast and seamless. When the primary server comes back online after an outage, WANdisco HADR will bring the primary server up-to-date with any new transactions that were committed to the backup server A computer in a network used to store copies of files from client machines or other servers. Such servers typically have their disks set up in a RAID configuration to provide fault tolerance. See backup program, RAID, SAN and LAN free backup. during the outage. Recovery happens automatically without any intervention from an administrator. --Makes outages and failover transparent to users as well as administrators. With WANdisco HADR, when the primary server fails, clients are dynamically rerouted to the backup server without administrator intervention. When the primary server becomes available, it's automatically resynchronized with the changes that were written to the secondary server during the outage. --Provides proactive monitoring capabilities that enable IT organizations to address problems before availability is impacted. --Delivers transaction-aware continuous real-time backup capability to ensure that the primary and backup servers are continuously in sync. --Provides optional integration with high capacity tape archiving solutions to allow source code repositories A source code repository is a place where large amounts of source code are kept, either publicly or privately. They are often used by multi-developer projects to handle various versions and developers submitting various patches of code in an organized fashion. to be backed up to tape. No other solution can provide WANdisco HADR's support for high availability, automated disaster recovery and continuous real-time backup over a LAN as well as a WAN, without requiring other third party hardware and software products and additional staff with the skills to support them. Availability WANdisco HADR is available now. WANdisco HADR can be implemented standalone, or in conjunction with WANdisco's multi-site development solutions for CVS (1) (Concurrent Versions System) A version control system for Unix that was initially developed as a series of shell scripts in the mid-1980s. CVS maintains the changes between one source code version and another and stores all the changes in one file. , Subversion and CVSNT. WANdisco also provides support and implementation consulting services for WANdisco HADR, as well as all of its other products.

The result of these efforts is new technology that fundamentally changes the way distributed nodes, or servers, interact to provide unprecedented levels of reliability, availability and scalability (RAS (1) See network access server. (2) (Remote Access Service) A Windows NT/2000 Server feature that allows remote users access to the network from their Windows laptops or desktops via modem. See RRAS and network access server. ) enabling the internet to realize its full potential. WANdisco has applied this technology to the development of its suite of multi-site SCM (1) (Software Configuration Management, Source Code Management) See configuration management. (2) See supply chain management. solutions for CVS, Subversion and CVSNT. For the first time a development team can truly be spread-out across the world and work as one unit, in real-time. Global 2000 companies rely on WANdisco's suite of SCM solutions for CVS, CVSNT and Subversion to enable them to distribute work based on where their talent is located, rather than on the basis of time-zone constraints. This results in dramatically reduced costs and significantly improved utilization of scarce resources. For more information, visit http://www.wandisco.com. |
