SATADOM
A SATADOM is a disk-on-module (DOM) form factor with an incorporated standard SATA data
connection. By default, the SATADOM comes with a power cable installed and is set in a Read/Write
position.
The SATADOM uses an onboard SATA controller and does not require an additional controller.
With Nutanix, you can locate the boot device on a separate controller from the data drives, which
improves system disk performance.

Motherboard (SATADOM) shipped with XC Series appliances is intended as an
appliance boot device.
NOTE: Write intensive activities and processes leveraged by XC appliances, are intended to take
place on the SSDs and HDDs and not the boot device.
The hypervisor boot device is not intended for application use.
WARNING: Adding additional write intensive software to the SATADOM boot disk results in heavy
wear on the device beyond design specifications resulting in premature hardware failure.
You should not run applications on the hypervisor operating system.
Examples of write intensive applications
Following are the examples of write intensive applications:
• System Center Agents.
– System Center Configuration Manager (CCMExec.exe).
– System Center Operations Manager (MonitoringHost.exe).

• Run Virtual Machines directly on the SATADOM. Ensure that the Virtual Machines run on Solid State
Drives (SSDs) and Hard Disk Drives (HDDs).
