C9400-SSD-960GB Description

The C9400-SSD-960GB is a Cisco Catalyst 9400 Series M2 SATA SSD module that adds local storage to a Catalyst 9400 supervisor for container-based application hosting. The module provides 960GB on the supervisor’s M2 connector, ships formatted EXT4 with EXT2, EXT3 and EXT4 supported, and mounts as disk0: for read, write, delete, format and copy operations. The SSD is not hot-swappable, so the system must be powered down to install or replace it, and Cisco IOS XE Everest 16.6.1 is the minimum release.

Application Scenarios

Container Hosting On The Supervisor

On a Catalyst 9400 core or distribution switch that runs container-based applications, the 960GB module gives the supervisor local disk0: storage for application images and their data.

Operational Files On disk0:

A supervisor that keeps operational files locally can use the module as disk0: and manage them with read, write, delete, format and copy operations from Cisco IOS XE.

C9400-SSD-960GB is the largest of the three Catalyst 9400 supervisor M2 SATA modules, 960GB against 480GB for C9400-SSD-480GB and 240GB for C9400-SSD-240GB; the comparison table shows the same interface, file systems and disk0: mount on all three, so capacity is the only reason to choose between them. 960GB matches the maximum SSD capacity that Cisco lists for every Catalyst 9400 supervisor, so this group has no larger option. A deployment that needs less local space for container-based application hosting can order C9400-SSD-480GB or C9400-SSD-240GB for the same supervisor M2 connector.

Ordering Checklist

  • Supervisor hosts: Install the module in a Catalyst 9400 supervisor C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2 or C9400X-SUP-2XL in a C9404R, C9407R or C9410R chassis. It is supervisor storage, not a line card, chassis or power option.

    We’ve never received a damaged shipment from Layer23. That’s a streak worth mentioning.

    Highly recommend Layer23 for anyone in B2B procurement. Wish the lead time was a bit shorter, but product quality made up for it.

Questions & Answers

  • Which Catalyst 9400 supervisors accept C9400-SSD-960GB?

    C9400-SSD-960GB plugs into the M2 connector of C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2 or C9400X-SUP-2XL. The supervisor sits in a C9404R, C9407R or C9410R chassis. The module is supervisor storage, not a line card, chassis or power option.
  • What is the minimum Cisco IOS XE release for C9400-SSD-960GB?

    C9400-SSD-960GB requires Cisco IOS XE Everest 16.6.1 or later. Run that release or a later one on the host supervisor, and power the system down to install the module, because the SSD is not hot-swappable.
  • Can C9400-SSD-960GB be replaced while the Catalyst 9400 is running?

    No. C9400-SSD-960GB is not hot-swappable, so the system must be powered down before you install or replace it. Plan the change for a maintenance window, and use a supervisor running Cisco IOS XE Everest 16.6.1 or later. The module sits on the M2 connector of the supervisor.
  • Which supervisors and chassis accept C9400-SSD-960GB?

    C9400-SSD-960GB installs in a Catalyst 9400 supervisor, which can be C9400-SUP-1, C9400-SUP-1XL, C9400-SUP-1XL-Y, C9400X-SUP-2 or C9400X-SUP-2XL. Those supervisors sit in a C9404R, C9407R or C9410R chassis. The module is supervisor storage, so it does not go into a line-card slot, and it adds no ports, PoE capacity or switching bandwidth to the chassis.
  • Which file operations does the disk0: volume on C9400-SSD-960GB support?

    The disk0: volume on C9400-SSD-960GB supports read, write, delete, format and copy operations. The default format is EXT4, and EXT2 and EXT3 are also supported. The same disk0: volume holds container images and their data when the supervisor hosts applications, so format it before the first use.
  • Which Cisco ordering description does C9400-SSD-960GB carry?

    Cisco lists C9400-SSD-960GB as the Catalyst 9400 Series 960GB M2 SATA memory option for the supervisor. The description shows that it plugs into the M2 connector on the supervisor, so match it to the supervisor in your chassis rather than to a line-card slot or a power supply.
