Cisco SSD Interfaces

Cisco offers two types of SSD interfaces for its networking devices:

  • SATA (Serial Advanced Technology Attachment) is a standard interface for connecting storage devices to computers. SATA SSDs are typically less expensive than NVMe SSDs, but they also have lower performance.
  • NVMe (Non-Volatile Memory Express) is a newer interface that is specifically designed for SSDs. NVMe SSDs offer much higher performance than SATA SSDs, but they are also more expensive.

Cisco devices that support SATA SSDs include the following:

  • Cisco Catalyst 9500 Series Switches
  • Cisco 4000 Series Integrated Services Routers
  • Cisco UCS E-Series Servers

Cisco devices that support NVMe SSDs include the following:

  • Cisco Catalyst 9600 Series Switches
  • Cisco 8000 Series Integrated Services Routers
  • Cisco UCS C-Series Servers

The specific SSD interface that is supported by a Cisco device depends on the model of the device and the software version that is running on it. You can check the Cisco documentation for your device to find out which SSD interfaces are supported.

Here is a table summarizing the key differences between SATA and NVMe SSDs:

Interface SATA NVMe
Performance Lower Higher
Cost Lower Higher
Availability  -
  More widely available  -
  Less widely available

The best SSD interface for your Cisco device depends on your specific needs and requirements. If you need high performance, then an NVMe SSD is the best option. However, if you are on a budget, then a SATA SSD may be a better choice.
