I worked most of my professional career as an AIX admin for banks (they seem to just love IBM) and i can tell you that they use Linux in abundance. For instance, my last client (one of the biggest german banks) had ~400 AIX systems, some few Solaris and HP-UX systems (together maybe a dozen) and ~1000 Linux systems (mostly SLES) in their data centre.

For SAP HANA you are even forcced to use Linux (IIRC RHEL, SLES or Ubuntu), because even on IBMs pSeries it doesn't run on anything else.

I wouldn't invest any time in learning HP-UX because i think it is dying a slow death (mostly because HP abandoned it after Intels plan to discontinue the Itanium), but other commercial UNIXes (that means mostly AIX and Solaris) are still going strong and it seems reasonable to learn them.

As of the threads title: the question IMHO is not so much "what is good" but "what will survuve on the market". I.e. with video, Betamax was good but VHS survived. If you invested money in the worse but surviving techology VHS you were better off in the long run, sad to say.

I hope this helps.

NAME

       lx - Linux branded zone

DESCRIPTION

       The  lx	brand  uses  the branded zones framework described in brands(5) to enable Linux binary applications to run unmodified on a machine
       with a Solaris Operating System kernel.

       The lx brand includes the tools necessary to install a CentOS 3.x or Red Hat Enterprise Linux 3.x distribution inside  a  non-global  zone.
       The  brand  supports  the  execution of 32-bit Linux applications on x86/x64 machines running the Solaris system in either 32-bit or 64-bit
       mode.

   Supported Linux Distributions
       The lx brand emulates the system call interfaces provided by the Linux 2.4.21 kernel, as modified by Red Hat in the RHEL 3.x distributions.
       This kernel provides the system call interfaces consumed by the glibc version 2.3.2 released by Red Hat.

       In addition, the lx brand partially emulates the Linux /dev and /proc interfaces.

   Configuration and Administration
       The  lx brand supports the whole root non-global zone model. All of the required linux packages are installed into the private file systems
       of the zone.

       The zonecfg(1M) utility is used to configure an lx branded zone. Once a branded zone has  been  installed,  that  zone's  brand	cannot	be
       changed	or removed. The zoneadm(1M) utility is used to report the zone's brand type and administer the zone. The zlogin(1) utility is used
       to log in to the zone.

   Application Support
       The lx zone only supports user-level Linux applications. You cannot use Linux device drivers, Linux kernel modules, or Linux  file  systems
       from inside an lx zone.

       You cannot add any non-standard Solaris devices to a Linux zone. Any attempt to do so will result in a zone that zonecfg(1M) will refuse to
       verify.

       You cannot run Solaris applications inside an lx zone. Solaris debugging tools such as DTrace (see dtrace(1M)) and mdb (see mdb(1)) can	be
       applied to Linux processes executing inside the zone, but the tools themselves must be running in the global zone. Any core files generated
       are produced in the Solaris format, and such files can only be debugged with Solaris tools.
