Lync Server 2010 Load Balancer Partners


This page describes which Server Load Balancer partners have completed
interoperability qualification testing with Lync Server 2010 and contains
pointers to accompanying deployment white papers hosted by the partner.

Usage

For qualification, Lync Server 2010 requires integrating hardware load
balancers in three deployment configurations. Hardware load balancers load
balance traffic across several servers.

  • Enterprise pool with multiple front-end servers: In this
    scenario, the hardware load balancer will be the connectivity point to multiple
    front-end servers in an Enterprise pool in consolidated and expanded
    configuration. In the expanded configuration, the hardware load balancer also
    load balances traffic to the Web Components servers of the Enterprise pool.
  • Array of Directors: In this scenario, the hardware load
    balancer serves as the connectivity point to multiple Directors in an
    array.
  • Array of Edge Servers: In this scenario, if the hardware
    load balancer supports multiple virtual IP addresses (VIP), it will serve as the
    connectivity point to both the internal and external NICs for multiple Edge
    Servers in an array. If the hardware load balancer only supports a single VIP,
    then two hardware load balancers are required to load balance Edge Servers, one
    for the internal NICs and one for the external NICs of the Edge
    Server.

    So we are talking a minimum of at least 3 load balancers in a true HA deployment correct?  1 for the Front End Pool, 1 for the Director Pool, and 1 for the edge pool as long as the HLB supports multiple VIP's.
