Tomas Basus - PeerSpot reviewer
IT Professional at NIPOS
Virtualization has reduced licensing costs and improved integration but still needs better performance insight
Integrations bring the biggest benefit to us. We use half of our virtual machines that are Microsoft, so it works better hosted in Hyper-V compared to VMware. Clustering and failover capabilities in the product help with our availability. It helped because we switched to Hyper-V because it was lower cost than paying for high availability in VMware. We need Microsoft licenses for virtual machines, so it costs less than buying two solutions for that. We have data center editions, so it did not cost us additional money compared to paying for high availability from VMware. I think it helped a little, but not so different compared to VMware regarding security and bandwidth optimization.

Virtualization has simplified partitioning and currently supports secure multi-tenant workloads
The ease of use of IBM PowerVM provides key benefits such as the installation being very easy, and the VIOS is really, really stable. IBM PowerVM is performing very well in supporting complex workloads. It's simple regarding the initial setup for IBM PowerVM. We always create two VIOS servers in IBM PowerVM to be compliant for security and to be compliant also for redundancy.
