Hi,
We have an issue with 2 Exchange 2013 Multirole Servers (CAS and MBX, one DAG with 3MDBs)
Both of them have a LAN NIC, located in address range 110.180.0.0/16 (this is one subnet for clients and servers, cross site)
Both of them had (i disabled this) an iSCSI NIC located in 110.188.0.0/16 (no gateway, dns, dns registration off,... as recommended by MS for cluster networks). This network is used for HP Storevirtual emails and alerting. Also Backups run over this nic.
When the iSCSI NiC is enabled, our outlook clients connect very slowly to exchange. It takes a 30 second average to connect (loading profile...). When the nics are disabled on both servers, the outlook clients connect perfectly.
Actually, we need the iSCSI connection, but then again we also need exchange...
Any tips or ideas or solutions we can implement? Everything is configured using MS's best practices.
Thaks!
