Enterprises planning to deploy Microsoft's Hyper-V hypervisor for virtualization can now run SPARC-based Solaris applications on their x86 Windows servers without porting or recompiling, thanks to “QuickTransit”, a solution from cross-platform virtualization solutions provider Transitive.
QuickTransit supports 64-bit distribution, so it runs on Solaris x86. Once QuickTransit has been installed, enterprises can install or copy SPARC-based (define) applications onto the x86 server. The applications will run the same way on the x86 server as they did on the more expensive SPARC servers without requiring a recompile.
