Please review this web site that talks about configuring shared file systems for SAS.  53875 - Shared/clustered file systems tuning guidelines (sas.com) There is a paper on there about best practices for Veritas. 

 

Also, please review this web site on configuring operating systems for SAS.  There are several papers on there about configuring RHEL.  SAS Support - Operating system tuning guidelines (service-now.com)   We are adding a few papers to this site about tunings for RHEL 8.
