We have ~110 host with 98% of them being WIndows VM running 2008 &nbsp;- 2012 R2 and deploy all VM using templates. Now for the longest time we have always used the LSI SAS which has been tried and true for a long time. One of my coworkers want to upgrade the WIndows OS templates to use the paravirtual. I know bac kin ESXi 4.x ther were issues using the Paravirtual on non-I/O heavy workloads but this have been correct. I am always very gun shy and like consistency in my environment.<br />
<br />
What are the pros / cons of switch to Paravirtual? Any issues with Windows 2012 R2, RDM's vmotions etc...

ESXi 5.1 and 6.0 and Gust LSAI SAS vs ParaVirtual

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.
