Software Load Balancers for Bare Metal

​Easily convert your existing hardware into a high performance load balancer with KEMP’s software load balancers for bare metal.

KEMP continues to innovate, with platform independent software Load Balancers such as our Loadmaster Load Balancer Operating System for Cisco UCS, HP ProLiant DL, Dell PowerEdge R and Oracle x86 Servers. The KEMP LoadMaster Operating System enhances enterprise application performance and availability by delivering application-aware, L7 traffic management and optimization that leverages your existing hardware.

The benefits of KEMP's software load balancers for bare metal are:

  • Proximity to servers/applications
  • Improved network bandwidth utilization
    • By cutting out the middle-man, there is no need for traffic between an application and the ADC to traverse the higher latency Layer 2 infrastructure.
  • Growth and scalability
    • Because our load balancer is integrated into your server, as dynamic workload requirements change, the load balancer function can simply be “moved” to higher or lower performing blades as needed.
  • Reduction of TCA and TCO associated with external hardware ADCs
    • Integration of the load balancer in your server ecosystem allows for re-use of the existing infrastructure and fabric for high-performance application delivery processing

See how you can turn your existing hardware investment into a high performance load balancer.
