Mod-27s will buy you back a lot. Yes, most large data centers hit this awhile 
ago.

You do not say what release of z/OS you are running, or what zSeries hardware.

Subject:UCB Constraint

We are reachiing the limit for the number of UCBs defined on the systems
in our SYSPLEX with 8 systems. We have about 1,600 left.
Have any of you run into this situation, and what have you done to get
around it? Mod 27, Mod 54, 
I know that there are installations that have SYSPLEXes that are larger
than ours. How do you folks deal with the UCB limit?
Thanks for any help you can give!!

Larger volumes.
FICON
  Bridge -- supports 4K
  Native -- supports many (I can't recall the number).

Dynamic PAV's -- not every volume needs an alias.
