I would recommend that you also license ESXi with vSphere Essentails and standup vCenter on XP system or a spare physical or virtual machine. &nbsp;<br />
<br />
The cost is $500 for 3 ESX/ESXi licenses and vCenter. &nbsp;It will provide proactive reporting on your vmware environment that you don't get with ESXi standalone or free. &nbsp;In addition it will allow you Update the ESX/ESXi host via update manager.

I am planning for a transition of Exchange 2003 on a physical box to Exchange 2010 on vSphere. &nbsp;I have about 35 mailboxes and will not have more than that for a while. &nbsp;What is a recommended approach as far as role installs are concerned? &nbsp;I have two Dell hosts configured with dual quads and 32GB of RAM and a MD3000i iscsi SAN. &nbsp;Should I perform a typical install and place all roles on one VM(Windows Server 2008 r2) with 4 vCPUs and 8GB of RAM or split the roles onto two VMs? &nbsp;Also, should I create a separate data store on the SAN with RAID 10 for best performance or will RAID 5 suffice? &nbsp; &nbsp;Anyone have a setup like this for small business? &nbsp;Any advice is appreciated! &nbsp;

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.
