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.
Important information about SATADOM
The SATA Disk‐On‐Motherboard (SATADOM) shipped with appliances is intended as an appliance boot device.
NOTE: Write intensive activities and processes leveraged by appliances, are intended to take place on the SSDs and HDDs and
not the boot device. Virtual Machines run on the SATADOM are not highly available and potentially ll up the local boot drive,
which results in crashing the host hypervisor. This adds additional wear on the SATADOM.
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 specications resulting in premature hardware failure.
Examples of write intensive applications
Following are the examples of write intensive applications:
• Hyper-V System Center Agents:
• System Center Conguration Manager (CCMExec.exe)
• System Center Operations Manager (MonitoringHost.exe)
• Write‐intensive Agents
• Databases
• Disk management utilities (third-party disk defragmentation or partitioning tools)
• Additional roles outside of the appliance’s intended use (web server, domain controller, RDS, and so on)
• Client‐based Antivirus
• Run Virtual Machines directly on the SATADOM. Ensure that the Virtual Machines run on solid state drives (SSDs) and hard disk drives
(HDDs).
