Important Information
 For general information about VMware vMotion, see VMware vMotion and CPU Compatibility Information
Guide at vmware.com .
 vMotion compatibility depends on the model and stepping of the processor involved. It does not
depend on the model of the PowerEdge system or the speed of the processor. Table 3 through Table 6
illustrate vMotion compatibility with respect to processors. For more processor-specific information,
refer to the knowledge base (KB) articles 1991, 1992, and 1993 at kb.vmware.com .
 For more information about Enhanced vMotion Compatibility (EVC) processor support, refer to the
VMware Knowledge Base article 1003212.
 To determine if the processor support exists in a specific ESXi release, see the specific Systems
Compatibility Guide at vmware.com/support/pubs .
 Each PowerEdge system model listed in Table 1 and Table 2 includes all currently supported processor
models.
 When you migrate between certain processor models, turn off the NX bit on the VMware vSphere
Client interface .
 Perform the following steps to turn off the NX bit:
o Right-click Virtual Machine and select Edit Settings→ Options→ Advanced Settings.
o Select the Hide the NX flag from guest option.
The NX bit is now turned off.
 VT must be enabled to run 64-bit guest operating systems on Intel platforms. For more information
about 64-bit guest operating system vMotion compatibility, see Table 3 through Table 6.
 Create consistent virtual switch names on each ESXi host.
 vMotion requires the setup of a Gigabit Ethernet migration network between all copies of ESXi. Dell
EMC recommends isolating this network from other production network traffic.
