Aruba CX 10000 Advanced case studies
Aruba CX 10000 Advanced · Put your knowledge to work in context.
The Aruba CX 10000 Advanced credential is aimed at network engineers, data center architects, and security-focused operators who design, deploy, or support the CX 10000 switch series. The platform's distinguishing feature is its embedded AMD Pensando DPU, which delivers line-rate stateful firewall, NAT, encryption, and telemetry services directly in the switch rather than in a separate appliance or hypervisor. The Aruba CX 10000 Advanced case studies are 5 cases and about 2,000 words.
1Sizing a DPU-Bound Firewall Policy for a Bursty East-West Workload
A CX 10000 pair enforces stateful policy on traffic between a 3-tier application: web (12 VMs), app (20 VMs), and db (6 VMs). The app tier issues short-lived, high-concurrency connections to the db tier (each app VM peaks near 40k concurrent TCP flows for ~90 seconds during batch windows, twice per day).

A data center has two pods, each with its own CX 10000 leaf pair and EVPN-VXLAN overlay, connected via border/spine layer. A shared services VLAN hosts DNS, NTP, and a jump host that every workload in both pods must reach.

An operator is introducing micro-segmentation on a CX 10000 pair protecting a live 3-tier app (web/app/db). Today all tiers share one flat subnet and rely on host firewalls.

Operations relies on a CX 10000 telemetry pipeline exporting flow and interface counters to an analytics platform. A gradual degradation (rising retransmits and tail latency on app- db traffic) went unnoticed for two days; dashboards showed 'green' because they chart average throughput and link up/down only.

A CX 10000 HA pair protects stateful east-west traffic. During a batch window, the active node reports a degraded DPU and the pair is considering a failover to the standby.
