DNS/DHCP High Availability

Executive Summary

In network environments requiring DNS architectural changes (such as additional servers), HA functions ideally since clients will always use the same DNS server. This also applies to other areas where DNS requires higher availability but where infrastructure would normally be too expensive. BlueCat Networks developed its XHA technology to provide dependable, robust, and highly available DNS services. Organizations can implement a HA solution transparently without affecting existing network configurations. A highly available DNS infrastructure reduces the risk of business interruption and help desk incidents of users experiencing DNS latency.

Key drawbacks inherent to the traditional method of DHCP scope splitting include potentially costly downtime, possible manual intervention and wasted IP address ranges. The Adonis DNS/DHCP appliance securely alleviates these drawbacks with the revolutionary Crossover High Availability (XHA) solution. The cross-platform, rich client, easy-to-use features of the Adonis Management Console includes wizards to support setup and conversion from other platforms.

The Proteus 5000 Enterprise IPAM appliance is based on state-of-the-art hardware that offers full redundancy. The dual processor, multi-core architecture offers performance and value for mission critical network environments.
