    Hi John!

     

    This is a bit unconventional, but you can check the max value by entering a ridiculously high value into the Cache Size field and submitting (ie 99000). Then the LTM will tell you the max value of your system in the following error message. :)

     

    Also, you can increase the allowed ram-cache percentage by increasing the ramcache.maxmemorypercent variable in the db (DO read about the risks involved though:

    As to the minimal cache value, that would be 1 mb.

     

    Please note that generally web applications needs less memory than you think and that any cache size value will be multiplied with the number of tmm processes. Ie, in your case I believe you have 8 tmm processes so 100mb will mean 800mb in actual memory usage.
