Hello,
Yes, Distributed Environment is still supported.
I would suggest to perform a Spectrum sizing:
http://consumer.interop.ca.com/sizer/
Run the $SPECROOT/perfCollector9 <SpectroSERVER_hosname>
Example:
$ ./perfCollector9 serverA
All the required information to fill in the sizer will be found in $SPECROOT/Performance/SpectroSERVER_hostname_SizerInfo.txt file
Except the event rate. The community thread below will explain where you can get it:
https://docops.ca.com/ca-spectrum/10-0/en/frequently-asked-questions#FrequentlyAskedQuestions-Performance
Q. How many traps can each SS handle efficiently?
A: 600 traps/second sustained and 1000 traps/second peak for a window of about 10 minutes. The SpectroSERVER will queue up traps if larger trap rates are experienced, however this leads to an increase in memory utilization during that time.
