Customers do as they have in the past when they divided up GS-320s or
GS-1280s into multiple partitions, yet needed redundancy: You consider
any cabinet to be a potential single point of failure and have multiple
cabinets (at least two) and cluster between them for availability (and
between cabinets at different sites for disaster tolerance).
And as Neil pointed out, being in a single cabinet isn't nearly the
availability challenge that it was back in the GS-320 days, since Blade
components tend to be hot-swappable and you don't have to take the whole
cabinet down for maintenance on one piece.
