It depends on the virtulisation technology adopted. AFAIK, Vmware is pretty good in their vmotion technology in providing High Availability on virtual machines.
on using clustered environment for High Availability by having redundant nodes is required when you need high availability. "availability, performance and cost - pick 2" <-- have a thought on this :-) On 7/24/07, Junhao <[EMAIL PROTECTED]> wrote:
Dear all, Since we are on the topic of virtualisation, I'm just curious what's everyone's take on virtualisation of hardware/servers versus not having a single point of failure (i.e. when the main server goes down, everything goes down with it). I'm presently considering setting up a secondary system which automatically kicks in if/when the primary system goes down. But this seems counter to the argument that virtualisation is a way to consolidate resources, no? -- Regards, Junhao [EMAIL PROTECTED] http://www.jmarki.net/ "Oops, what happened?", said Confused Jmarki _______________________________________________ Slugnet mailing list [email protected] http://www.lugs.org.sg/mailman/listinfo/slugnet
