Some. If you've decided to use SLES on System z, then we might be able to provide some technical assistance. Contact me off list if that is the case. > Need a migration path. > > Some questions: > > Can z114 be upgraded to include zBx or must I upgrade to a z196 for that? > Can zBx be SYSPLEXed between 2 CECs? > If not, how do I eliminate the SPF, how do I do failover for the blade > servers? If you have highly available applications running on Solaris, then you must be running some form of an HA cluster, or the applications themselves provide the HA. In either case, HA clustering is available on Linux, or the applications themselves will still be providing it. > How do I convert Solaris to zLInux under z/VM? Solaris is not supported by > zBx. The zBX has nothing to do with z/VM anyway. You would be running the Linux systems on the System z itself, most likely on IFLs. There is a version of OpenSolaris that runs on System z, and was approved by IBM for use on IFLs. I'm only aware of one company that provides any support for it (they did all the porting work), and I'm not sure if the project survived the acquisition of Sun by Oracle. > Must I recompile the applications running under Solaris to run them under > zLinux? If they're written in a compiled language, then yes. IBM has a source code analyzer for C that will warn you about any Solaris-specific usages in the source code. The tool was developed specifically with the intent of helping customers migrate from Solaris to Linux. If you can't find it via Google, let me know and I'll see if I can track it down.
