Small businesses though? never had that problem. most looking to cut rising licensing costs had moved to x86 by the mid nineties (or SGI if they still wanted jaw-dropping performance.) by 2007 SUN was pushing rope; x86 had proceeded to x64 and most applications were running fine. multicore, distributed, and load balanced architectures had been developed and been in existence thanks to the GNU ecosystem of FLOSS for 6-7 years already. SUN shuffled their IP to Oracle and shuttered the doors of a once proud computer company.
sparc, the oracle boot environment, virtualization, you name it and x86 will do it cheaper and without the burden of recompiling everything. Sure, linux runs on sparc but far more development has proceeded in the X64 and emerging ARM platform than Oracle can ever hope to evolve from their sparc offering.
