Hi Naveen,

SID is System Identifier it is used to Identify Uniquely in the Landscape

Instance Number is to dentify Uniquely in the SID

The SID should be Only one to the System

But Each SID can have 00 to 96 (97,98,99 not used for us) Instances's

if you see the SM51

Server Names : <HOSTNAME>_<SID>_<INSTANCE NO>

Thanks & Regards,
