[cisco-voip] UC on UCS auto failover in hardware

[Wellnitz, Erick A.]

I sould qualify my first question as sometime in the not-too-distant future.

Does this mean that the automatic ‘load balancing’ between nodes will be supported as well?  How about virtualized storage?

Any timeframe as to when ESXi 5 will be supported?

Eric,

That used to be 100% true.  For better or worse Truth is a function of time T=f(t).

VMotion is starting to be supported:

I think what you’re describing is VMotion and is very much not supported.  (Moving an active VM on a blade that is having trouble to another blade in production)

I do believe you can shut down the VM completely, copy it to a new blade, and turn it back up.

I am going to deploy UC on UCS and I am aware that we can move the UC application from one blade server to other slot or UCS chassis easily. However the question is how much redundancy/failover can be supported with UC on UCS system.

An example for CallManager; if the Subscriber 1 server is down, all the voice endpoints will failover to the backup CCM server automatically. This is application redundancy and auto failover.
As for hardware ie: blade server /disks are down for any reason, would UCS system be able to auto failover the UC applications into another spare blade server?
As far as I know from reading some doco, we have to manualy dissassociate service profile and reassociate that to the spare blade and then power it ON to achieve the recovery.
Can anyone with UC on UCS experience share this thought?

Thank you,
