Exchange 2007 NLB on VMware

HI,

I am looking to load balance my 2 CAS servers using Windows 2008 NLB.  Both servers are on VMware and from what I am reading, VMware recommends multicast, but MS recommends unicast.  I am looking for guidance from others who might have had a similar implementation.

Thanks
David

Hi,

we have a medium-small project using Microsoft Windows 2008 R2 as the domain servers and to service many Microsoft services.

We are using NLB as a standard for Printing Services, Terminal Services Gateway, AD SelfService and ServiceDesk Plus.

We are using the configuration in Multicast IGMP (depending from your network device) in our 16 nodes vSphere 4.0U2 environment.

For the AD SelfService and ServiceDesk Plus we have excluded the Load Balancing functionality leaving one server as the primary and the secondary server assume the cluster ip address only if the primary goes down.

Hope this can help you.

We've got two HUB/CAS boxes running in VMWare and we are running Multicast IGMP.  Each server only has a single NIC.  We've been running this way for over a year.

From what I understand, VMWare acts like a host on the network and not a switch.  As such, VMWare is unable to enumerate the Windows unicast NLB address.

Definitely follow VMWare's recommendation.
