With the latest IBM i Technology Refresh, IBM is giving the anti-VIOS group a feature they have been requesting: the capability to easily share a tape library among multiple logical partitions, or LPARs without involving VIOS, SANs, or multiple adapters.

IBM is calling the new feature “IBM i Virtualization for Tape Libraries,” and it’s based on RFE (request for enhancement) number 127631. While the words “tape libraries” and “virtualization” are in there, this is not a virtual tape library (VTL) solution. That already …

Cloud Walkers Makes LPARs More Native On IBM i

They are, in no certain order: the PowerVM hypervisor, the Hardware Management Console (HMC), the Virtual I/O Server (VIOS), the PowerVC variant of OpenStack that is native to Power Systems, and external disk arrays, …
