Cisco - Data Center Trainings

Cisco Data Center: architecture, fabric and automation for critical infrastructure

Cisco Data Center covers the technologies dedicated to data center infrastructure: Nexus switches, Application Centric Infrastructure (ACI) fabric, Nexus Dashboard automation and NX-OS operations. In Geneva, Lausanne and across French-speaking Switzerland, private banks, international organisations, telecom operators, hosting providers and large industrial enterprises build their data centers and private clouds on these Cisco technologies, often interconnected with Azure or AWS public clouds.

ITTA offers the complete Cisco Data Center certification path. The path is structured around the DCFNDU fundamentals (Understanding Cisco Data Center Foundations), the CCNP Data Center DCCOR core (Implementing and Operating Cisco Data Center Core Technologies), the DCID (design) and DCIT (troubleshooting) specialisation modules and the ACI family (DCACI, DCACIA, DCACIO, DCACIT). The NX-OS modules (DCNX, DCNXA) and Nexus Dashboard (DCNDE) complete this path on the operations side.

Our Cisco Data Center trainers are engineers and architects actively working on production data center projects for Swiss and international companies. They master Nexus 9000 deployments, ACI fabrics, VXLAN interconnects, multi-site architectures and Nexus Dashboard automation. This field expertise feeds every training session and lets us illustrate each concept with lived cases.

Whether you are a data center engineer, ACI administrator, infrastructure architect, network engineer specialising in data center or DevNet professional moving towards automation, our Cisco Data Center training in Geneva and Lausanne gives you the skills expected on production engagements in French-speaking Switzerland.

DCFNDU: data center entry foundation

DCFNDU (Understanding Cisco Data Center Foundations) is the entry course for profiles discovering Cisco data center technologies. The programme covers Nexus switches, NX-OS, storage (FCoE, iSCSI), virtualization, fabrics and unified architectures. This foundation is generally recommended before DCCOR for profiles not coming from a data center background.

CCNP Data Center: DCCOR, DCID, DCIT

CCNP Data Center is structured around the DCCOR core (Implementing and Operating Cisco Data Center Core Technologies) and concentration modules: DCID (Designing Cisco Data Center Infrastructure) for architects and DCIT (Troubleshooting Cisco Data Center Infrastructure) for operations engineers. This family targets network engineers consolidating their data center expertise or architects in charge of designing future infrastructure.

Cisco ACI: DCACI, DCACIA, DCACIO, DCACIT

The ACI (Application Centric Infrastructure) family regroups four modules: DCACI (Implementing Cisco Application Centric Infrastructure) for deployment, DCACIA (advanced) for advanced configurations, DCACIO (operations and troubleshooting) for operations and DCACIT (troubleshooting) for incident resolution. These modules cover the design and operation of multi-site ACI fabrics, inter-tenant contracts, APIC integrations and best practices.

Nexus 9000, NX-OS and Nexus Dashboard

DCNX (Implementing Cisco NX-OS Switches and Fabrics in the Data Center) covers Nexus switches in standalone NX-OS mode, complementing the ACI modes. DCNXA (Implementing Cisco Nexus 9000 Switches in NX-OS Mode Advanced) deepens VXLAN-EVPN architectures and multi-site deployments. DCNDE (Cisco Data Center Nexus Dashboard Essentials) covers the Nexus Dashboard platform for centralised steering and automation.

Building your Cisco Data Center path by profile

For a profile discovering the data center, DCFNDU is the natural entry. For a data center engineer, DCCOR is the mandatory CCNP core, complemented by DCID (architect) or DCIT (operations). For an ACI-oriented profile, DCACI is the entry, followed by DCACIA and DCACIO depending on the trajectory. For an NX-OS engineer, DCNX then DCNXA for VXLAN-EVPN architectures. Profiles oriented towards automation and NetDevOps complete with DCNDE and Cisco programmability modules. Our pedagogical team supports you in defining the path according to your goals.

Cisco Data Center and related skills

Cisco Data Center certifications fit into a broader ecosystem. The Cisco Enterprise Networking catalogue covers CCNA and CCNP Enterprise certifications (ENCOR, ENARSI, ENSLD), a complementary network foundation for data center engineers. The Cisco Security Solutions catalogue covers SCOR, SISE, SVPN and CyberOps, important for data center perimeter security. The systems and networking sub-domain regroups all network courses. Virtualization training covers VMware vSphere, complementary to hybrid data center architectures. Cloud computing training covers Azure, AWS and GCP, relevant for hybrid cloud interconnects.

Cisco Data Center trends in 2026

Cisco Data Center is evolving rapidly with the generalisation of VXLAN-EVPN architectures, Nexus Dashboard automation and native integration with public clouds. Cisco ACI multi-site and Cisco Cloud ACI enable fabrics that extend between private data centers and public clouds. Programmability (Python, Ansible, Terraform) is being durably embedded in operations practices. Observability and AI-driven steering (AIOps) are rising in operations team expectations. Our pedagogical content regularly integrates these evolutions to stay aligned with current practice.

Cisco Data Center training in Geneva, Lausanne and online

All our Cisco Data Center courses are available on-site in our Geneva and Lausanne centres, as well as in interactive virtual classroom with a certified Cisco instructor live. Our sessions are organised in 5-week cycles. Each session includes hands-on labs on Cisco Modeling Labs platforms and access to official Cisco Learning resources. Customised corporate training is also available at your premises, in Geneva, Lausanne, Vaud and across French-speaking Switzerland, with a programme adapted to your data center architecture.

FAQ

What is the difference between Cisco Data Center and Cisco Enterprise Networking?

Cisco Enterprise Networking covers campus and WAN technologies (switching, routing, SD-WAN, SDA). Cisco Data Center covers technologies specific to the data center (Nexus, ACI, NX-OS, data center automation). The two families share a common network foundation but target different audiences.

Which Cisco Data Center certification should I start with?

For a beginner profile, DCFNDU is the recommended entry. For an experienced engineer, DCCOR is the mandatory CCNP Data Center core. For an ACI-oriented profile, DCACI is the entry module.

Do your Cisco Data Center courses include hands-on labs?

Yes, every session includes hands-on labs via Cisco Modeling Labs or equivalent platforms. The exercises are aligned with the competencies assessed by the certification exams.

Are your Cisco Data Center courses available for companies?

Yes, the entire Cisco Data Center catalogue is available in-house, in Geneva, Lausanne and in virtual classroom, with a programme adapted to your data center architecture and validation needs. Our team builds the specifications with you and organises sessions according to your calendar.
