Optimize your Architecture
Data center networks around the world are shifting to spine-and-leaf1,2 architecture to simplify scaling bandwidth, deliver consistently lower latency and reduce overall costs.
Unlike traditional 3-tier networks, every leaf (access) switch connects to every spine (aggregation) switch ­ and every spine switch only connects to the leaf switches. Every connection to the data center network is made through a leaf switch. To increase overall bandwidth, all you need to do is add another spine switch. To add access ports, simply add another leaf switch. Every leaf is only two hops away from every other leaf for consistently low latency. And every link is always active, so your network delivers the maximum bandwidth with the fewest switches.

1 ACI mode is designed for spine-and-leaf only and requires the Cisco Application Policy Infrastructure Controller (APIC).
2While this guide focuses on the spine-and-leaf architecture, the Nexus 9000 and 3000 can be configured for either spine-and-leaf or traditional 2-tier and 3-tier architectures in NX-OS mode.

Hardware innovation
All networking platforms depend upon their network processors and the other microchips on which they run. That's why we have some of the world's best Application-Specific Integrated Circuit (ASIC) designers. We are committed to driving the industry forward when we see that customer needs aren't being met by merchant silicon. A great example of this are the Cloud Scale ASICs.

Three key decisions
Your organization's data center architecture is unique. When you consider your combination of network administrators, applications, software developers, users, computing, storage, and public cloud usage, no other organization is an exact match for your needs. That's the reason we've built such broad capabilities into the Cisco Nexus 9000 portfolio. As you consider how it could best meet the needs of your organization, there are three key decisions you'll need to make.
Which network operating system is right for you? Both Cisco ACI1 and NX-OS2 have their benefits. You will need to pick one as your spine-and-leaf operating system.

Cisco ACI1 The ACI1 network operating system
dramatically simplifies SDN and delivers endto-end policy automation by taking advantage of Cisco's Cloud Scale ASICs that connect physical
and logical networks.

NX-OS2 The industry's
most programmable network operating
system with open APIs. With
over 50,000 customers, NX-OS is the world's industryleading network operating system for data centers.

Which one is right for you? It really comes down to your people. ACI1 makes automation dramatically easier. Your people won't have to learn tools like Ansible, Puppet, or Chef.
They'll have a single-pane of glass for managing physical and virtual
networks, and they'll be able to deploy and maintain
applications faster and easier.

Which leaf switches do you need?
You will likely need many different leaf switches to meet your computing, storage, and core networking needs. If you are new to the Cisco Nexus 9000 Series Switches, we recommend that you focus on switches with Cloud Scale ASICs.

Scale
Cloud Scale ASICs Built on next-generation process technology (16 nm), our Cloud Scale ASICs deliver significant advantages over
merchant silicon: Fundamentally faster due to
16nm processes Substantially more features
in hardware Higher performing buffers
Line rate encryption and analytics

Cisco ACI1 technology As the industry moves toward Software-Defined Networking (SDN) and infrastructure as code, there is no industry standard for combining physical and virtual networks. We invented Cisco ACI1 to connect physical and virtual networks for deploying policy-based automation
end-to-end.

FCoE and Fibre Channel
While all Cisco Nexus 9000 leaf switches
support Fibre Channelover-Ethernet (FCoE),
only the N9K-93180YC-FX can be configured for Fibre Channel ports to connect to your SAN.)

What is the best spine switch to standardize on? Unlike leaf switches, you will want to pick a single spine switch to standardize on. Key considerations include:

Total spine bandwidth In most cases, you will start
with two spine switches and have the option to expand to up to 6 spines.3

Leaf uplinks You'll want to make sure your spine is compatible
with all your leaves' uplinks. You'll need a modular spine if want to have both QSFP28 and
QSFP+ uplinks.

Operating system You'll want to make sure your operating system supports all of your spine
and leaf switches.

1 ACI mode is designed for spine-and-leaf only and requires the Cisco Application Policy Infrastructure Controller (APIC).
3We strongly recommend you start with at least two spine switches. You will also likely be limited to six spine switches because that is the most common number of uplinks for leaf switches. The range shown here is the total maximum system bandwidth for two to six spine switches.
