<br>
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.<br>
