List of Catalyst Center appliance hardware specifications.

Cisco supplies Catalyst Center in the form of a rack-mountable, physical appliance. The second-generation Catalyst Center appliance consists of either a Cisco Unified Computing System (UCS) C220 M5 small form-factor (SFF) chassis or Cisco UCS C480 M5 chassis, both with the addition of one Intel X710-DA2 network interface card (NIC) and one Intel X710-DA4 NIC. Six versions of the second-generation appliance are available:

  • 44-core appliance: Cisco part number DN2-HW-APL

  • 44-core promotional appliance: Cisco part number DN2-HW-APL-U

  • 56-core appliance: Cisco part number DN2-HW-APL-L

  • 56-core promotional appliance: Cisco part number DN2-HW-APL-L-U

  • 112-core appliance: Cisco part number DN2-HW-APL-XL

  • 112-core promotional appliance: Cisco part number DN2-HW-APL-XL-U

The following tables summarize the appliance's hardware specifications.
