We have a requirement where we have to transfer our SAS servers to Enclave Network model. At the moment our servers are on Legacy system.
I understand that SAS has got predefined ports for SAS components. However following link says that for 'TCP port for middle-tier cache communications', the default port varies from 0 to 65535 and for the 'Cache Locator membership port range' needs 1024–65535 ports.
So I was wondering whether Network team needs to open such a huge number of ports for the new system ? or it is ok if only few ports are defined. Should I understand that Network team has to open so many firewall rules ?
For the rest of the services, most of the services mention a range from 0 to 9, which is for accomodating up to 10 SAS levels. But if you are deploying just 1 level, you can restrict the number quite a lot. Pay attention to the list, and the list provided by your SAS installer consultat (checklist.pdf) and you should be able to accomodate firewall to specific port numbers.
