Last month to mark the one year anniversary of the OpenIndiana project there was the release of OpenIndiana 151a, the latest build of this Illumos-based Solaris operating system. I have finally had time to try out this latest OpenIndiana release and, of course, to run a few benchmarks.
For server-type tasks, it looks like 151 matches or beats 147 on most tests, but on many workstation-oriented tests (code compilation for example) it seems to have actually regressed a bit. Oh well. I guess you can't have everything.
If you want a server that:
-provides a well seasoned file system that scales beyond imagination, snapshots, is it simple to extend
-provides OS Virtualization that is very lightweight (Zones), when you don't want the overhead of machine virtualization
-has current versions of Java available
-has current versions of a great machine virtualization available (VirtualBox) and KVM
For all of these reasons I have been pleased with OpenIndiana 151a - one server has provided me 3 OS Virtualized PCs and 3 Hardware Virtualized PCs -
