[cisco-voip] UCS chassis redundancy

[Lelio Fulgenzi]

People already have subscribers at remote locations, I figure, instead of a server, use the router. 

Of course, there would have to be the same latency requirements met. 

Who needs ESRST when you have a subscriber out there. ;)

I am going to go with “NO” on that. Imagine database replication across all sites? Imagine doing major version upgrades.

won't it be great when the VMware service modules on the ISR G2s support installing CUCM on it? a full subscriber at each remote site. ;)

I'm seeing a lot of B-series at the data center and a C-series at a remote site or DR. Otherwise, a second chassis isn't *too* expensive. The bulk of the cost is in the blades and the 6100s. You still need power supplies, IO, chassis, but it's not too bad. Seeing a decent amount of 2nd chassis as well. A lot of the DC types that are putting their blades in there as well help offset the cost.

Has anyone had issues with the UCS blade chassis being a single point of failure? What happens if the chassis itself fails? DO people have redundant chassis installed? A C series UCS for disaster situations? 



I don’t like having all my eggs in one basket.
