Hi Rusty,

Unfortunately it is not that easy :)
We already have multiple environments and consolidating ( all based on
Linux x64 ). However, as you rightly pointed out to the NBU planning and
performance tuning guide, sizing beyond 10k jobs is not documented :)

It's perfectly fine to add more resources to the master server, we just
need to know what are those resources and how much to add, that is the

The environment is indeed based on two sites in HA cluster (VCS), but I
doubt that it is possible to split them atm (there are a few data domains
that are not supporting AIR quite yet. I heard it is coming in DD OS 5.3
and plugin 2.6 but they are not GA yet)

I have got a handful of responses from SYMC off-list but nobody is willing
to commit on sizing figures :)

Thanks anyway, will share what I'll end up with.
