Solaris have many editions: - Solaris Express, Community Edition - Solaris Express, Developer Edition So wich version is mainly for critical mission server?
There are several answers - all depend on how much risk you can absorb and the context behind "mission critical". If your company /will/ go out of business if the system crashes and can't be brought back up immediately, you really need a supported system - either with your own support staff or $somebody elses$ - who can keep things running smoothly. If you need a low risk system that can be installed and ignored, rather than one that needs to be upgraded every so often, then it may be that neither of these choices is what you want, and a fully supported (service contracts ...) OS like Solaris10 might be a better choice. That is, in many cases, the combination of the phrases "mission critical" and "development snapshot release" is a syntax error. If your definition of critical isn't so critical, then SX-DE may be OK. It /is/ supported, but (IIRC) not at the same levels as Solaris10. Its benefit over SX-CE is that it is tested to (at least) ensure that it isn't Dead-on- Arrival (DOA). Oh, and it had a bunch of stuff bundled with it (compilers...) If you are able to deal with more risk and self-assembly, SX-CE is still a fine choice. We (Sun) run the latest development release of SX-CE on the main departmental server for ~1000 users, including the Solaris OS, Net and Clustering development teams in California. Sometimes it crashes, sometimes the support team needs to fall back to a previous SX-CE release; many times we find - and fix - bugs that we would not have found any other way. Myself, while I'm comfortable running a selected SX-CE release on a departmental level mission critical server, a personal web/development system or as a main server for a small to medium sized software/web startup, I'd probably go with Solaris10u3 or u4 anything significantly larger, simply because the risk tolerance is lower there... -John _______________________________________________ opensolaris-discuss mailing list [email protected]
