If you have:
... then you are ready for Power Integrated Facility for Linux (IFL) - which is a offers a package of 4 cores and 32 GB of memory at a special low price (given the resources, you can order more than one IFL)
You have to legally agree to prove you are only running Linux on these IFL cores/RAM (not running AIX or IBM i) but that can be done using PowerVM features on the HMC (HMC is mandatory on these large machines). Please ask your IBM or Business Partner rep." for the IFL price. Don't forget this is al a non-disruptive upgrade as the CPUs and Memory are already in the machine - just add a code in the HMC and they become available to use and assign to LPARs / VMs.
But why did I say "... and AIX" ?
Well, you might find yourself in this condition:
You originally purchased and licensed 48 CPU cores for AIX and IBM i and have 16 dark CPU cores and RAM to switch on later.
But over time you added Linux to the mix of operating systems as below:
So now you purchase three IFLs = in total 16 CPU cores and 96 GB of memory, as below:
Next you create a Shared CPU pool so that AIX or IBM i can't run on the IFL CPU cores thus making sure only Linux LPARs (VMs) get placed in the IFL Shared CPU pool.
This frees up 16 CPU and the memory, previously used by Linux, but now ready for AIX and IBM i use again for:
Note: This is what you originally paid for when we started, as below:
This allows the purchase of CU cores and RAM at low prices (x86 server like prices) and all three operating systems can benefit.
I would recommend you check your licenses to make sure you are fully covered, particularly if there is lots of history changes in the past.
