regarding SIC

Hi All,

Good Day..

We are using Sep 12.1 RU1 MP1 on a windows Architecture, and we are planning to deploy SIC on our environment, we need to confirm few things regarding SIC.

1. Is it mandatory to give username & password on SIC server settings
2. What is keeping SIC server (any hash values, vote counts),  so what would be the disk usage ?
3. Port number 9006 is used for Status Service , what it exactly mean is it required to open between clients and SIC server

Regards
