RE: RHEL Cluster & RHEV



Well, till now, no virtulization vendor can provide truly 0% downtime
product, even vmware's FT&DRS or Citrix's Xenmotion or MS's Live
migration, there will be nearly 1 or more seconds the client will lose
connection to the virtual server. From the migration's theory(memory
copy), we can know there won't be 0% downtime.
I haven't tested RHEV, but I've tested Redhat Xen live migration, there's
also a short pause, so I don't think the RHEV can provide 0% downtime
neither.

Hi all,

Need your info. Does RHEL Cluster can provide 0% of downtime, means I need
"zero downtime" cause my application needs to always available on any
condition, even 1 minutes off. Maybe you can give me some documentation?
And, could you please to tell me, how can I create RHEV to fail over
condition?
Thanks in advance for your help.

Rgds,
Wahyu
