Service Delivery Manager at a computer software company with 10,001+ employees
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.
OB
Head Systems Administration/Security at Nigeria Inter-Bank Settlement System PLC
Infrastructure efficiency has improved significantly with quick server provisioning, though physical to virtual migrations need a streamlined in-house tool
From my experience with Nutanix Cloud Infrastructure (NCI), there is one area that needs improvement. When moving a critical infrastructure from a physical machine to Nutanix Cloud Infrastructure (NCI), we currently have to use a third-party tool to convert the physical machine to a VM. We have to use VMware converter to perform this conversion before moving it to Nutanix Cloud Infrastructure (NCI). I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.
