• Network Services: Designing for critical network services such as load balancing (e.g., using Cisco Application Centric Infrastructure – ACI's integrated load balancing or external ADCs), DNS, DHCP, and Network Time Protocol (NTP) is also covered. The focus is on integrating these services seamlessly into the overall data center network design to ensure application availability and performance.

Compute Design - 25%

The compute domain focuses on the design of the server infrastructure, primarily leveraging Cisco Unified Computing System (UCS) solutions, and integrating them with virtualization platforms.

• Cisco UCS Architecture: This includes understanding the various components of Cisco UCS – chassis, blade servers, rack servers, Fabric Interconnects, and I/O modules. You should be able to design solutions utilizing both blade and rack-mount form factors, considering their respective strengths and use cases within a data center environment.
• Cisco UCS Management: Design considerations for UCS Manager and UCS Central are vital. This involves understanding how to create service profiles, pools, policies, and templates for automated server provisioning and consistent configuration across the data center. Scalability and management hierarchy for multi-domain UCS environments are also important.
• Server Virtualization: While not specific to a single vendor, this section expects you to design compute solutions that integrate effectively with server virtualization platforms like VMware vSphere, Microsoft Hyper-V, and open-source alternatives. You'll need to understand how to allocate resources, design for high availability (HA) and disaster recovery (DR) in virtualized environments, and optimize performance.

Key Design Principles for Cisco Data Centers

Beyond the individual components, successful Cisco data center design hinges on applying overarching principles that ensure the infrastructure is robust, flexible, and future-proof. These principles often intertwine across the various syllabus domains.

Cisco ACI Design Principles

Cisco ACI redefines network design with its policy-driven approach. Key principles include:

• Application Centricity: Designing the network from the perspective of the application, defining policies based on application requirements rather than network topology.
• Centralized Automation and Orchestration: Leveraging the APIC (Application Policy Infrastructure Controller) for unified management and automation of the entire fabric, ensuring consistent policy enforcement.
• Microsegmentation: Implementing granular security policies between application components, even within the same subnet, using EPGs and contracts.
• Openness and Integration: Designing for seamless integration with virtualization platforms, cloud services, and third-party network services through open APIs.

Cisco UCS Design Considerations

Designing with Cisco UCS goes beyond just selecting servers; it involves architecting a cohesive compute environment:

• Stateless Computing: Utilizing service profiles to abstract server identity, allowing for rapid provisioning, migration, and disaster recovery.
• Scalability and Modularity: Designing UCS domains that can scale easily by adding blades, rack servers, or fabric interconnects, without re-architecting the entire system.
• Integration with Virtualization: Optimizing UCS for various hypervisors, including network and storage connectivity for virtual machines, and ensuring performance and high availability for virtualized workloads.
• Operational Simplicity: Leveraging UCS Manager and UCS Central for simplified, unified management of compute resources.

Cisco HyperFlex Design Solutions

HyperFlex brings the benefits of hyperconverged infrastructure to Cisco data center design:

• Cluster Sizing and Scalability: Designing HyperFlex clusters based on workload requirements (CPU, memory, storage capacity, IOPS) and planning for future expansion.
• Data Locality: Understanding how HyperFlex stores data across the cluster to optimize performance and resilience, and designing accordingly.
• Network Integration: Seamlessly integrating HyperFlex into the existing data center network fabric, considering network performance and redundancy for inter-node communication and client access.
• Resilience and Data Protection: Designing for built-in data replication, snapshots, and disaster recovery capabilities of HyperFlex.

Cisco Data Center Network Design Strategies

Effective network design strategies are fundamental for modern data centers:

• Spine-Leaf Architecture: Implementing highly scalable and low-latency spine-leaf topologies for predictable performance and simplified cabling.
• Overlay Networks (VXLAN EVPN): Designing for flexible, scalable, and multi-tenant overlay networks that decouple virtual networks from the underlying physical infrastructure.
• Multi-Tenancy and Segmentation: Employing VRFs, VDCs, and ACI constructs to logically separate network resources for different applications or tenants, enhancing security and resource isolation.
• High Availability and Redundancy: Designing redundant paths, devices, and protocols (e.g., vPC, FHRPs) to ensure continuous operation and minimize downtime.

Designing Cisco Data Center Security

Security must be an integral part of every design decision:

• Segmentation: Implementing microsegmentation with ACI or traditional VLAN/VRF segmentation to contain threats and limit lateral movement within the data center.
• Firewall Integration: Designing for the strategic placement and configuration of firewalls (e.g., Cisco ASA, Firepower Threat Defense) for perimeter security, internal segmentation, and application-specific protection.
• Intrusion Detection/Prevention: Integrating IPS/IDS capabilities to monitor traffic for malicious activity and prevent known exploits.
• Access Control: Designing robust identity and access management solutions to control who can access data center resources and how.

Cisco Data Center Infrastructure Architecture

Ultimately, all these elements converge into a holistic architecture. This involves designing for:

• Scalability: Ensuring the design can grow to meet future demands without requiring significant re-architecture.
• Resilience: Building in redundancy and fault tolerance at every layer to withstand failures.
• Performance: Optimizing for low latency and high throughput to support critical applications.
• Manageability: Designing for ease of operation, automation, and troubleshooting.
