The first is whether your datastore has the capacity and performance to meet the requirements of the application. &nbsp;If so, there are few reasons to use a raw device mapping, and several reasons to switch to a virtual disk.<br />

The reasons to convert to a virtual disk are a) standardization (all VMs behave the same way), b) reduction of complexity, and c) backup/recovery/replicatio<wbr />n. &nbsp;If you're using a product like Veeam or vSphere replication, then using VMDKs is very desirable.

We want to make a PTV where the physical machine, have a mounted Lun.<br />
The Virtuel machine will then have the same name and IP.<br />
The way to do so, is that to add the storage to the Virtuel machine as Raw device mapping?<br />
Or would that be wrong, if so what would be the rigtht way?

VMWare

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
