need to add disks to asp 1 when your system actually has plenty of

discourages me from using multiple ASPs.

Every cycle of CPU not being utilized is similarly /wasted/ capacity, yet the same perception is rarely held with regard to its utilization; mostly because the capacity was /planned/ to cover what was required spanning times of greater need for that resource. Of course for that, there is possibly CoD built-in; a less plausible concept, similarly for online storage.

As long as the secondary ASPs are not the /old-style/ that prohibit libraries, they could be used in an emergency [arising apparently, from poor planning... just as could be considered, any extremely excessive capacity on those secondary ASPs]. Such an ASP with extra capacity could also be used, with proper planning, to store some seldom-referenced data or ¿whatever? else that does not impact the journaling environment too much.
