Certainly, there will be a limit eventually. What you ought to be asking to
determine if you're approaching the limit is
1. Is the response time (time it takes to serve up data) significantly
different than when there was less data in the data store? (This implies
that you've been measuring and keeping the results.)
2. Where is the server waiting? (CPU? I/O resources? storage (aka
paging/swapping)?)
3. Is the real I/O configuration a limiting factor? (If so, dividing the
load among multiple servers won't change that)

Subject: zvm 5.2 storage limits, zlinux?
We have a virtual zLinux SUSE 10.1 file server on zVM 5.2 that currently
supplies over 600 Gigs of DASD (SAMBA 3 file storage) to end users. Is
there a point (technical or logical) when we should build a second server
rather than continuing to grow this server?
Thanks
