ACI Hardware Component

Cisco ACI consists of following hardware component:

  • APIC Controller
  • Spine Switches
  • Leaf Switches

Cisco Nexus 9000 Series Switches:

Cisco Nexus 9000 Series Switches have capability like industry-leading performance, power, port density, and open programmability innovations. Nexus 9000 series Products include following variants switches ( 9500,9300 and 9200):

Cisco Nexus 9500 Series ( Spine Modular Switches ):

  • Cisco Nexus 9516 Switch
  • Cisco Nexus 9508 Switch
  • Cisco Nexus 9504 Switch

Spine switches (Cisco Nexus 9336PQ, 9364C, 9504, 9508, and 9516 switches and some standalone switches )

These fixed-form-factor spine switches:

  • Cisco Nexus 9336PQ Switch
  • Cisco Nexus 9364C Switch (which requires Cisco ACI software Release 3.0 or newer)

The connectivity to the leaf nodes is provided by these line cards some of them are discussed here

  • N9K-X9736PQ line card
  • N9K-X9732C-EX line card
  • N9K-X9736C-FX line card (which requires Cisco ACI software Release 3.0 or newer)

Cisco Nexus 9300 Series ( Standalone Switch ):

  • Cisco Nexus 93180YC-EX Switch
  • Cisco Nexus 93180LC-EX Switch
  • Cisco Nexus 93180YC-FX Switch
  • Cisco Nexus 93128TX Switch
  • Cisco Nexus 93120TX Switch
  • Cisco Nexus 93108TC-EX Switch
  • Cisco Nexus 93108TC-FX Switch
  • Cisco Nexus 9396TX Switch
  • Cisco Nexus 9396PX Switch
  • Cisco Nexus 9372TX Switch
  • Cisco Nexus 9372PX Switch
  • Cisco Nexus 9336PQ ACI Spine Switch
  • Cisco Nexus 9332PQ Switch

Following are some Cisco First-generation ACI leaf switches:Nexus 9332PQ,9372TX-E,9372PX-E,9372PX,9396TX,93120TX,9396PX,9372TX,and 93128TX

Following are some Cisco Second-generation ACI leaf switches:  

In second Generation Cisco Nexus ACI Switches there are two categorization : Nexus 9300-EX and 9300-FX platform switches.

Some of the EX and FX Series switches are :

Cisco Nexus 93108TC-EX,93180LC-EX, 93180YC-EX,9372PX-E,9372TX-E,93108TC-FX,93120TX,9372PX,9372TX,9396PX,93128TX,93180YC-FX,9332PQ, 9348GC-FXP, and 9396TX

Cisco Nexus 9200 Series:

  • Cisco Nexus 92304QC Switch
  • Cisco Nexus 92300YC
  • Cisco Nexus 92160YC-X Switch
  • Cisco Nexus 9272Q Switch
  • Cisco Nexus 9236C Switch

Naming conventions for the leaf nodes

Following are the naming convention for (N9K-C93xx) and spine line cards (N9K-X97xx) available for the Cisco ACI fabric.

The trailing -E and -X signify the following:

  • E: Enhanced. Switch is capable to classify traffic into EPGs based on the source IP address of the incoming traffic.
  • X: Analytics. Hardware is capable to support analytics functions. The hardware that supports analytics includes other enhancements in the policy CAM,buffering capabilities, and ability to classify traffic into EPGs.

For port speeds, the naming conventions are as follows:

  • PX: 1/10-Gbps Enhanced Small Form-Factor Pluggable (SFP+)
  • TX: 100-Mbps, 1-Gbps, and 10GBASE-T copper
  • Y: 10/25-Gbps SFP+
  • Q: 40-Gbps Quad SFP+ (QSFP+)
  • C: 100-Gbps QSFP28

BW Calculation :

The Switch model with 93xx or 97xx shows the port count if all ports are of same speed or if ports are of different speed they represent Sum of all ports, expressed in multiples of 10-Gbps

For example, N9K-C93180YC-EX has 48 ports of 25 Gbps (Y) + 6 ports of 100 Gbps (C), for a total of (48 x 25 + 6 x 100) / 10 = 180 Gbps.

APIC Controller Hardware:

For APIC controller Cisco uses UCS series Servers, Below are the specification: 

  • UCS C Series Server : C220 M3  ( used as generation 1 )
  • UCS C Series Server : C220 M4  ( used as generation 2 )
