Dear Team,
Please help me understand below queries related to sap HANA 
Query No. 1)
While reading HA200 book I came across the below image for installation of distributed system (in which mount point has subdirectory 'SID' )
However in Standard Installation guide it is showing other directory ( mount point /HANA has subdirectory 'SHARED' )
may I please know what is standard naming convention for sub directories ? (SID,DATA,LOG or SHARED,DATA,LOG).
Query No. 2)
In HANA DB distributed installation why there is requirement of separate directory SYS (usr/sap/<sid>/SYS) on Every host?
In distributed ABAP system; we mention "profiles_directory_location" when adding dialog instance. It acts as central location of all profile files and no addition directory is required on application server level. May I please know if there is specific reason for not following that norm while installing addition HANA dialog (slave) instance.
Query No. 3) This is big one (I think my skull is thick); this is regarding profile parameter files.
Assume:
<Hana DB sid>= ABC. common mount point is /HANA. Two DB application server host1 (Instance = HDB01) and host2 (Instance = HDB02). Both are serving database ABC.
Questions:
1) Is it allowed in HANA to have Different system number to the application server instance that serve same DB ? (in above case host one has got system No. 01 and other got 02)
2)Please let me know all DB configuration//global/local profile files that are there in HANA with respect to above example. and their names also. It's too much confusing for me.
Regards,
Arthur Rodrigues
