KEMP Technologies LoadMaster DR
Disaster Recovery & Multi-site Load Balancing

LoadMaster DR offers the ability to move past the single datacenter, allowing for multi datacenter load balancing and high availability.   LoadMaster DR ensures that even when a primary site is down, traffic is diverted to the disaster recovery site. LoadMaster DR also includes the ability to ensure clients seamlessly connect to their fastest performing  datacenter.

LoadMaster DR load balances using Domain Name Services (DNS) technology. Using DNS to direct traffic allows you to load balance to any Internet Address and ignore protocol level configuration on your load balancing devices.

Loadmaster DR offers “Round Robin” load balancing for all active datacenters, which includes support for weights and a chained failover option for disaster recovery.  Loadmaster DR securely and seamlessly integrates with LoadMaster to offer “Real Server Load” load balancing, in which Loadmaster DR uses local datacenter metrics provided by LoadMaster, allowing clients to connect to the least busy datacenter.

High Availability & Reliability

LoadMaster DR helps prevent service outages by quickly detecting server and datacenter failures and then directing traffic. Monitoring and load balancing are based on layers 3 and 4 of the Open Systems Interconnection Basic Reference Model (OSI). Included in HA is the ability to have two appliances, protecting against introduction of a single point of hardware/network connectivity failure. Each individual LoadMaster DR can also be configured to provide network link-layer redundancy.

Speed

LoadMaster DR’s intelligence ensures that your mission-critical servers are continuously available and performing reliably. LoadMaster DR can monitor server and application load. This information is then used to intelligently direct user requests to the cluster that is most available. By intelligently redirecting traffic, LoadMaster DR eliminates server overload conditions and round trip propagation delays that may slow performance, allowing you to increasing end-user application speed.
