Kemp LoadMaster for Free Awesome!! A Free Load Balancer for Any Workload

KEMP gives away the LoadMaster for free. Now the virtual appliance is available in a free edition too. Available for all supported hypervisors (VMware, Hyper-V, enz).

The free VLM has some limitations, for instance the HA setup with an active and hot stand-by unit is not supported. Another important limitation is that the free LoadMaster doesn’t come with the awesome support paying customers receive. Also there are some bandwidth and SSL TPS limitations, all in all not much special for most home, lab, testing and other non-production deployments.

    The Free LoadMaster Includes:

  • Layer 4/7 load balancing
  • Content switching
  • Caching, compression engine
  • MS Exchange 2010/2013 optimized Smile
  • Pre-configured virtual service templates Smile
  • IPS engine
  • High Availability
  • Edge Security Pack (ESP) – a Microsoft TMG replacement Smile
  • GSLB multi-site load balancing

      Kemp Loadmaster: Drop Connections on Real Server Failure & Drop at Drain Time End

      I want to refer to two features within Kemp Loadmaster:
      Drop Connections on Real Server (Exsist from 5.x) (Default not enabled!!).
      Failure &
      Drop at Drain Time End (New feature at 7.04) (Default not Enabeld!!)

      Drop Connections on Real Server Failure

      By default existing connections are not closed if a Real Server fails. This can lead to issues with Outlook clients if an Exchange CAS server fails. A solution to this is to enable the Drop Connections on RS Failure option which can be found on the System Configuration > Miscellaneous > L7 Configuration screen in the WUI.

      When this option is enabled, LoadMaster tracks all the incoming connections and which Real Servers they are connected to. When a Real Server fails, all connections to the Real Server are immediately dropped, forcing the connections to reconnect to a different Real Server.

      Enabling this option has the added benefit of allowing relatively higher Idle Connection Timeout values to be set as the danger of the client retaining a connection to a failed server is removed.

      Drop at Drain Time End

      By default existing connections are not closed when a real server is disabled. This can lead to issues with Outlook clients if an Exchange CAS server is administratively disabled. A solution to this is to enable the Drop at Drain Time End option which can be found on the System Configuration > Miscellaneous > L7 Configuration screen in the WUI.

      When this option is enabled, LoadMaster will sever all existing connections to a disabled server after the L7 Connection Drain Time is reached. Clients will then be fored to reestablish a connection to one of the remaining Real Servers.
