Oracle Solaris is great due to the fact that it actually is meant for high-end servers.
Oracle Solaris is designed for high-end server performance and database optimization, offering robust backup capabilities and built-in virtualization. Known for its exceptional stability and scalability, it supports effective hardware utilization. However, it requires specific hardware and is more complex to use compared to Linux. High costs and sometimes inaccurate memory usage figures are noted drawbacks. Users suggest unifying the SPARC and x86 variants for better flexibility.
