The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco Catalyst 9400 is a next generation modular switch that lets you host applications for packet collection and analysis, testing, monitoring, and so on. To support the storage needs for these applications, the Cisco Catalyst 9400 Series Supervisor has an M2 connector that hosts a 22x88mm M2 SATA flash card. SATA configuration ranges from 240GB, 480GB to 960GB.
The default file system format of SATA is EXT4. However, SATA supports all extended file systems-EXT2, EXT3 and EXT4.
The SATA device has the following characteristics:
Files stored on the M2 SATA partition are compatible with files stored on other devices.
You can copy, or, store files between M2 SATA and other types of devices such as USB, eUSB, flash, and other IOS-XE file-system or storage.
You can also read, write, delete, and format the SATA device.
.Non-EXT based file systems are not supported on M2 SATA.
You cannot remove the M2 SATA device without powering off the Supervisor.
You cannot use M2 SATA to boot images from rommon.
You cannot upgrade the firmware on the M2 SATA drive.
You cannot use M2 SATA to execute emergency install of images.
Cisco Catalyst IOS XE Release 16.9.1 gives you the ability to monitor the health of the device through CLIs. You can monitor internal hot-spots, flash wear-outs, and hardware failure of the SATA device and alert your users about a SATA failure. These users can then backup data and obtain a new SATA device.
A linux deamon smartd starts when the SATA is inserted into the Supervisor. By default, the polling interval is set to 2 days for offline test, 6 days for short test and 14 days for long test. The warnings and error messages are saved in /crashinfo/tracelogs/smart_errors.log and are also sent to the IOSd console.
The S.M.A.R.T. feature and smartd daemon are enabled by default when the SATA device is detected by the switch.
 Note |
If the SATA is not detected after insertion, check the existing file system on the device. If it is not EXT based, SATA will not be detected. In that case, change the filesystem to EXT and reinsert the SATA. |
The following CLI shows the logs from the smartd daemon:
Switch# more crashinfo:tracelogs/smart_errors.log

SMART overall-health self-assessment test result: PASSEDThe mounted file system from the SATA flash card is accessed at disk0:. Use the show file systems command to view the details of each type of available filesystem.
Copying files to and from bootflash: or usbflash0: is supported.
To format a new Flash Disk, use the format disk0: command.
The format command recursively deletes all files on the device. This command fails if any file is open during its execution.
