Dell PowerEdge R520 Technical Manual page 35

One of the key features for virtualization on the PowerEdge R520 is the support for a fail-safe
hypervisor. By running a hypervisor on an optional SD card and installing a backup copy on the
other mirrored SD card, you can protect against hardware failure and maximize virtualization uptime.
Table 20 highlights the virtualization support for the R520.
