Cisco 9336PQ vs. N9K-X9736PQ 40Gb Spine Line Card Cisco 9336pq and N9K-X9736PQ 40Gb Spine Line Card, what are the differences? About ACI SPINE Cisco nexus 9000 switch users always have some questions related to the Cisco ACI. For example, is there a way to take advantage of ISSU/dual sup failover in a 9500 in ACI mode? How to get from Nexus ACI mode to NX-OS mode issue? What are the differences between Cisco 9336PQ and N9KX9736PQ 40Gb Spine Line Card? Now, let’s come to the last question: the differences between these 2 pieces of equipment: Cisco 9336PQ and N9K-X9736PQ 40Gb Spine Line Card. We know that Cisco Nexus 9000 switches operate in Cisco NX-OS Software or Application Centric Infrastructure (ACI) modes with ground-breaking Cloud Scale ASIC technology. They are ideal for traditional or fully automated data center deployments. And all Nexus 9K switches can operate in standalone mode. Many also support ACI. Can anyone tell me the differences between these 2 pieces of equipment? Other than the fact that one is a standalone switch and the other is a 9500 line card, my understanding is that they have the same internals/ASICs? My understanding is that the difference is really just one of scale, is that true? Cisco 9336PQ vs. N9K-X9736PQ 40Gb Spine Line Card Similarities: 1. Only supported in ACI 2. Only to be used as a spine 3. 36x40G nonblocking (no oversubscription) switching 4. Support the same 40G transceivers 5. Both use a mixture of third party and Cisco ASICs Differences: Form Factor
9336 = fixed switch
9736 = module for 9500 chassis
Scalability 9336 = 36x40G nonblocking
*9504 = Up to 144x40G (128x40G nonblocking) *9508 = Up to 288x40G (256x40G nonblocking) * Assumes all 9500 line card slots are populated with 9736PQ modules. To achieve full bandwidth, you will need 6 fabric modules Reference Links: Cisco Nexus 9500 Platform Switches for Cisco Application Centric Infrastructure Data Sheet Cisco Nexus 9504 Switch Cisco Nexus 9508 Switch Cisco Nexus 9336PQ ACI Spine Switch Cisco 40-Gigabit Ethernet Transceiver Modules Compatibility Matrix Both contain a third party and Cisco Alpine ASIC.
N9K-C9336PQ-Cisco Alpine ASIC and third party chips are both on the board. N9K-X9736PQ-Cisco Alpine ASIC is on the line card. Third party chips are on the fabric module.
