What a good reply looks like here
Good replies deal with the user's technical requirements, the tradeoffs, deployment experience and how to evaluate options. If you have a connection to a product being discussed, disclose it. Avoid promotional language and don't push people to your own content.
Sample reply: For server burn-in testing, it may help to separate hardware validation from workload simulation and work out which components are failing manufacturer tests. Are you mainly trying to stress CPU, memory, storage or networking? And do you need a bootable environment, or something that runs inside the installed operating system? If you share the server model and the kinds of failures you're seeing, people can recommend tools that fit your process.
When to skip r/sysadmin
This community is usually not worth your time if you want broad brand promotion, direct lead generation through advertising, or a place to sell non-IT services. It fits better if you want to join specific infrastructure and sysadmin discussions where you can add relevant expertise without promoting yourself.
