Hi Sudhir,
I'm afraid, I do not fully comprehend your question.
For the first part, simultaneous GUI access to FS7300 or any other IBM FlashSystem running Storage Virtualize, indeed is possible.
Neither there is a consoleProperties.xml file around, nor is there a need to tamper with any file.
Last but not least, the Storage Virtualize cli accessable through ssh, is a restricted BASH shell (RBASH), which allows only required commands so one cannot inadvertently do any damage.
For the 2nd part:
The difference between SI Free and SI Pro is in the SI interface you access through a web browser, nothing different to install locally.
