The Cisco Secure Network Server (Cisco SNS) 3800 series appliances are based on the Cisco Unified Computing System (Cisco UCS) C225 M8 Rack Server and are configured specifically to support Cisco Identity Services Engine (Cisco ISE). Cisco SNS 3800 series appliances are designed to deliver high performance and efficiency for a wide range of workloads.

The Cisco SNS 3800 series appliances are available in these models:

• Cisco SNS 3815 (SNS-3815-K9)

• Cisco SNS 3855 (SNS-3855-K9)

• Cisco SNS 3895 (SNS-3895-K9)

The Cisco SNS 3815 appliance is ideal for small deployments.

Cisco SNS 3855 and Cisco SNS 3895 appliances have several redundant components, such as hard disks and power supplies. They are suitable for larger deployments that require highly reliable system configurations. Cisco SNS 3895 is recommended for the PAN and MnT personas.

Note

The Cisco SNS 3855 appliance can be configured with one hard disk or four hard disks. We recommend that you enable only the PSN or pxGrid persona if your Cisco SNS 3855 appliance is configured with only one hard disk.
