Hi Forum,

some general question on the failover config for iSCSI.

Background:
- 2 Open-E DSS
- 4 NICs each
-- 1 NIC LAN (Management, SMB NAS acccess)
-- 1 NIC replication
-- 2 NICs Storage iSCSI VLAN (MPIO)
-- 2 Virtual IPs running on the 2 Storage VLAN NICs

My questions is about
1) the Network interface for unicast.
In the webcast on the setup of failover (with Xen) it is told to set this on the LAN NIC...but does this make sense? Shouldn't it be better to places this on the NIC for the replication? So the management traffic on the failover config is not going over switches but directly between the two nodes?

2) network of ping nodes
What is your experiences about the network for the ping nodes?
We've chosen the two hosts in the Storage iSCSI VLAN as ping nodes as this network is the relevant for some decision on doing some failover or not...

What do you guys think?
