solaris x86 vs Enterprise Linux
 

Hello,

Sun have Solaris x86 version which is now certified for many mainstream hardware verdor like HP Proliant server, Dell PowerEdge servers etc.

I want to ask is solaris x86 version is recommended for production server. or we should use this version only for learning and should use only sparc servers in production environment.



On x86 hardware which is more better Solaris x86 or RedHat Enterprise Linux RHEL5 :)

Not to mention Sun own x86 servers range.
Of course x86 servers are suitable for production. There are many factors to decide what server to use there and the CPU architecture isn't the most important. x86 servers are generally in the lower end while SPARC ones are more in the medium to high end range in term of performance, throughput, # of cores, size of memory supported, redundancy ...
That depends on which set of criteria are important to you. There is no such thing (yet ;) ) as one OS fit all needs

the one that you are better familiar with

I've got x86 and x64 Solaris servers in production and they're fine. I personally prefer the SPARC architecture, but there's nothing that makes Solaris on x86 any worse than any other x86 OS.

As far as Solaris vs. RHEL, go with what you know best. I've found Solaris to be less quirky/more stable, but less feature rich.
