virtualization

what is the advantage of VMware virtualization with regard to memory and hard disk as compared to physical environment

The long and short of it is resource utilization, while memory is mostly statically assigned/leveraged other aspects such as cpu and disk space are dynamically leveraged.

CPU is generally used in a threaded manner so unless the VMs are doing work, your CPU remains idle.

Disk space can be dynamic as well and affords you the option to shrink or increase as needed.

Big picture:
more available resources in a flexible environment to scale up or scale down based on demand instead of having multiple hardware components sitting idle.

Of course going beyond the question you asked and becraig's explanation, taking the VM route will open many other doors. For example: More granular backup option, business continuity with replication, the ability to move servers between physical servers ( hosts ).........

Not to mention if you are able to baseline your organization's needs the ability to bring home value in recovered costs and future savings through virtualization, could mean everything for your career :)

I recently saved ~2M and expanded opex revenue from customers by ~3M from less than 500K in memory purchases.

You could be a hero if you do it right !!!!

Virtual or Physical?

it does not talk much about technologies...
