RE: RHEL Cluster & RHEV



Hi Wen,
Thankyou for replied. Can you share how many time did you need to use Redhat Xen live migration, is it failover?
Have you tested for RHEL Cluster failover condition, how many time RHEL Cluster can handles the failed node to switch another one?
I need this info to assess my application.
Thank you all for your cooperation.

Thx & Rgds,
Wahyu

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.

Rgds,

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
