Maximum File Auditing Securitly log size for Unity?

Does Unity have an equivalent to the VNX security.evt log which tracks all the security audit events (e.g. time user logged on, etc) for activities on file system shares?  What is the maximum size security log for file systems access auditing?

Previously for the VNX,  the security.evt maximum log size was 512KB and there wasn't a direct way to increase that size.  Retaining more audit information involved numerous steps, including creating separate file systems and moving that security.evt to the newly created file system .    Has Unity overcome this, or what would be involved to increased that log size limit?

Thanks!
