We use random access pools, how do you know what your thread limit
is....we've never had any issues with ours but we're thinking about
adding a lot more. What's the biggest reason you do/don't use
devclass=file over disk storage pools....arguments either way?

Be careful with how many disk pool volumes you create. Each volume uses
1 thread, add this to all of the other threads in use, our TSM server
would die at around 1800 active threads.

Subject: [ADSM-L] Random Access Disk Pools
I have heard in the past that random access disk pools can become
fragmented and practically unusable after a while. I was wondering
if anyone sees this in the real world? I posted the other day about
managing predefined volumes in a file type devclass, and the only
answer I got said they were using random access pools. I would MUCH
rather have a random access pool, so if there is no problem with
this, I will convert over to random access. Thanks for any input.
