With the exception of the embedded Oracle System Assistant flash drive (which is reserved for Oracle System Assistant), you can install the operating system on any of the storage drives installed in the server. These include hard disk drives (HDDs) and solid state drives (SSDs).
For servers equipped with Fibre Channel PCIe Host Bus Adapters (HBAs), you can choose to install the operating system to an external FC storage device.
The server ships with an embedded Oracle System Assistant flash USB drive that contains the Oracle System Assistant, device drivers, and firmware for Oracle ILOM, BIOS, and supported IO devices. During the installation of all supported operating systems, this USB flash drive is detected as a SCSI disk with a single partition that is read/write capable and displayed as Oracle_SSM in the list of drives. You should be careful not to overwrite this device when performing any of the following operations:
Operating system installations
Disk partition or formatting operations
General disk, partition, or filesystem maintenance
In the event that this USB flash drive is overwritten, the original contents can be restored. To restore the contents of the USB flash drive, obtain the Oracle System Assistant recovery and ISO update image and use it to perform a restore operation.
For instructions for downloading the Oracle System Assistant recovery and ISO update image and restoring the server's Oracle System Assistant USB flash drive, see the Administration, Restore Oracle System Assistant.
