• With onset of affordable 100G in the

Aggregation layers, existing rack

components need to connect to 100GbE

Fabric

• Optimize infrastructure with 10GbE down to

the rack and 100GbE up to the fabric

• Dell has responded with 2 new families:

– S4100 Series

– S4200 Series

25GbE in the Rack

Take advantage of embedded 25GbE

I/O’s shipping in the latest generation

of servers, storage & networking

• Expand use of virtualization

technologies in both servers and

storage

• Grow use of cloud-based and web-scale

technology

• Increase use of flash technology in

storage systems requiring high-speed

I/O

• Increase I/O performance for multi-

processor servers

• As soon as 25GbE hits economies of scale (near parity with 10G) -- 25G will become the de-facto standard.

• 25G down and 100G is the coming default build demand. Better utilization of existing components

• Dell Responds with multiple 25G TOR options

– Z9100-ON – 25G Breakout Support

– S6100-ON – 25G Breakout Support

– S5048-ON – Native 25G Support

– S5148-ON – Native 25G Support

Containers and Microservices

• Single-host networking: Private network

within host (NAT for outside)

• Multi-host networking evolution:

• Bridged: Containers connected to

Linux Bridges (L2 virtual switches)

• VXLAN encapsulation between

hosts for L2 network

• MacVlan: Each container gets an

individual MAC and IP in the same

subnet as host

• IPVlan: Each container shares

same MAC as host and individual

IP in any subnet

Linux Containers Networking with Docker

• Software architecture pattern possible with

today’s technologies (containers, network

virtualization, cloud computing)

• Improves process isolation, security,

restartability, and upgradability

• Increased East-West traffic from servers

Microservices

Analytics with In-band Network Telemetry (INT)

• Improve monitoring of P+V network

traffic and fault isolation

• Real time

• Low CPU overhead (Data plane)

• End point (P or V) monitoring

• Latency

• Link utilization

• True paths

• Packet-level granularity

• Push model

• Under the scope of the P4 consortium.

Model sponsored by Dell EMC, VMware,

Intel, Arista and others

In-band Network Telemetry (INT)

How it works

• INT-aware devices insert INT messages

in packets, real-time and transparently

• INT-aware devices can consult the

information and expose data to clients

• INT-aware devices could also react upon

INT data

• INT messages are removed at destination

What is Intent Based Networking

1. Translation and Validation– The system takes a higher-level business policy

(what) as input from end users and converts it to the necessary network

configuration (how). The system then generates and validates the resulting

design and configuration for correctness.

2. Automated Implementation – The system can configure the appropriate

network changes (how) across existing network infrastructure. This is typically

done via network automation and/or network orchestration.

3. Awareness of Network State – The system ingests real-time network status

for systems under its administrative control, and is protocol- and transport-

agnostic.

4. Assurance and Dynamic Optimization/Remediation– The system

continuously validates (in real time) that the original business intent of the

system is being met, and can take corrective actions (such as blocking traffic,

modifying network capacity or notifying) when desired intent is not met.

“Networks are holding

businesses back as most

enterprise networks are

complex, rigid, hard to

change and slow to

provision, hard-coded

and downright slow to

change any kind of

Cloud Service Provider - Itconic

Why Pluribus / Dell:We gained a future-ready network for our cloud

services by working w Dell

Customer Comments - López García explains: “We wanted

to implement a more open solution, specifically on

networking, giving us greater freedom to make changes as

we needed.”

Cisco solutions were “too predefined” and lacked

adaptability. Opinion among key stakeholders was that

Cisco didn’t focus enough on its relationships with partners,

particularly organisations such as VMware, which would

play a central role in Itconic’s cloud services platform

Big Cloud Fabric is open, simple and economical alternative to ACIA Better Alternative to Cisco ACI

Challenges:

• Proprietary: HW-heavy, Vendor lock-in

• Complex: Box-by-box control plane, Pro-service necessary,

Confusing Taxonomy

• Cost: Still Expensive

• Company: Reorgs, Talent depletion, Low Morale

Confusing & Unnecessary Taxonomy:

• Promise theory, Contracts, EPG

Advantages:

• Open: HW/SW disaggregation, Vendor choice

• Simple: No complex protocols, zero-touch

• Economical: Commodity Bare-metal HW

APIC: Application Policy Infrastructure Controller

Very large System Integrator Feedback

• “Four people worked on different tests but every one of us

was impressed with the ease of use and quality”

• “Done demos internally and to several customers…

consistently received very positive feedback, even from SDN

skeptics”

• “ACI is complicated, customers are confused even when

Cisco presents it, has only partial CLI”

APIC is a policy controller, not SDN controller

Gartner: Cisco ACI is NOT SDN
