Challenges

The increasing demand for servers and virtualization platforms inflates the TCO of infrastructure.

Standalone virtual hosts cannot quickly move VMs to redundant servers for software or hardware firmware updates, and need to do so on a case-by-case basis, resulting in repetitive O&M workloads and prolonged working hours.
