We're thinking to virtualize on vmware esx some production
systems that are cross clustered between themselves with
Lifekeeper but have some doubts regarding the ha monitoring
and failover mechanism :
- if we move each SAP instance on a standalone virtual
machine, how we can manage OS failovers without using any
cluster aware solution (is that possible) ?
- is vmware esx capable of switching the vitual machine on
another host ?
- and what happens with SAP up and running (is there any
- do we have to install a second virtual machine to
replicate the physical clusters we're actually using (thus
replicating the whole infrastructure)?
And another question : is the SLES 10 high availability
agent for SAP certified (I'm talking about this project
http://developer.novell.com/wiki/index.php/Cluster_ha) ? For
which releases ?
We have SAP releases starting from 40B to 700 so the
solution must be cross compatible.
Many thanks to all and cheers,
