Cisco C9400-SSD-960GB | 960GB M.2 SATA SSD Module for Catalyst 9400 Supervisor

Q: Which Catalyst 9400 supervisor models support the C9400-SSD-960GB?
A: The C9400-SSD-960GB is compatible with all Cisco Catalyst 9400 Series supervisor engines, including C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2, and C9400X-SUP-2XL. The M.2 connector is integrated into each supervisor to host this 22x88mm M.2 SATA module.

Q: What is the primary purpose of this SSD module?
A: The SSD provides local storage for container-based application hosting, IOS image storage, streaming telemetry data, network logs, and other SD-Access features. It enables the supervisor to run advanced network automation, analytics, and monitoring applications directly on the switch without relying solely on flash memory.

Q: Can I upgrade an existing Catalyst 9400 supervisor with this SSD?
A: Yes, the C9400-SSD-960GB can be installed into any Catalyst 9400 supervisor with an available M.2 connector. It is a field-replaceable module that expands the storage capacity from the base 240GB or 480GB configurations up to 960GB for customers requiring additional storage for applications and data.

Q: Does this SSD affect supervisor redundancy or performance?
A: No, the SSD operates independently and does not impact supervisor engine redundancy or switching performance. Files stored on the M.2 SATA partition are compatible with other storage devices and can be copied between flash, USB, and eUSB. The system automatically checks and repairs the ext2 filesystem on each boot.

Q: What happens if the SSD fails?
A: The Catalyst 9400 Series supervisor will continue normal switching operations if the SSD fails, as core IOS XE software runs from flash memory. However, applications, logs, and data stored on the SSD will be unavailable. Cisco recommends using redundant supervisors in critical deployments to ensure continuous operation and data availability.
