Below are some best practices under VMware Virtualized Environment

-  Use VMware vCenter Server

-  Make vCenter Server highly available

-  Be aware of virtual machine time considerations

-  Configure maximum queue depth for HBA cards

-  Allocate only as much virtual hardware as required for each virtual machine (floppy, CD-Rom, etc)

-  Use separate virtual switches for the ESX service console, VMkernel, and virtual machines

-  Use guest operating systems that are supported by ESX

-  Use vSphere Client to create VMFS partitions
