Exchange CAS WNLB array on VSphere4 - multicast mode

Ivan-Aust — Wed, 23 Mar 2011 06:57:36 GMT

I am looking for the correct procedure for configration of a Procurve 8212zl for WNLB in multicast mode (recommened by VMWare)so Outlook clients on a separate internal subnet can access the CAS array.

This seems to be common question with the implementation of Exch2010 but answers and procedures are very hard to come by.

Any help appreciated.

Hi,

weÂ´re just build up a Exchange 2010 CAS Array with vShphere 4.1

We just setup a NLB Cluster from this howto:
http://howtoexchange.wordpress.com/2009/12/16/configuring-client-access-array-for-exchange-2010-walkthrough/

and had no Problems to connect to the CAS Array from another vlan.
Maybe you have to configure the ESX to support NLB. YouÂ´ll find a howto at the Vmware KB
