LoadMaster DR offers the ability to move past the single datacenter, allowing for multi datacenter high availability, even when a primary site is down, traffic is diverted to the disaster recovery site. Also included in LoadMaster DR is the ability to ensure clients connect to their fastest performing datacenter.  

The LoadMaster DR offers the same management interfaces as KEMP’s Server Load Balancer (LoadMaster) hardware appliances, including all the foundation technology such as syslog logging, email notifications,  interface bonding, and Gigabit support. LoadMaster DR provides advanced application health checking, to ensure that unavailable services or datacenters are not visible to clients.  Health checking can occur at the services level or even the site level, allowing for flexible decision making on when traffic should be diverted per Fully Qualified Domain Name (FQDN). 

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.  LoadMaster DR can be deployed in a distributed (Active/Active) high availability configuration, with both appliances securely  synchronizing information. Introducing LoadMaster DR in your existing Authoritative Domain Name Services (DNS) requires minimal integration work and risk, allowing you to fully leverage your existing DNS investment. 

LoadMaster DR is easy to set up, and easy to manage.  LoadMaster DR is a self-contained ‘plug and play’ appliance that doesn’t require the additional installation of software on your servers.  Network management is made easy, administrators can deploy new servers and take individual servers offline for routine maintenance without disrupting services to end-users.   Integrating the LoadMaster DR into an existing DNS infrastructure can be done with no service impact and allows for distributed administration.    

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.  

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.  

Scalability 

LoadMaster DR solves the scalability “dilemma” by continuing to support increasing network server workloads and still providing high reliability.  LoadMaster DR offers:
