What does the Cisco Data Centre Network Architecture hope to achieve (3 bullets)?

-Consolidate and virtualize computing, storage and network resources.
-Deliver secure and optimized employee, partner and customer access to information and applications.
-Protect and rapidly recover IT resources and applications.

What are the 3 building blocks of the Cisco Data Centre Network Architecture (3 bullets)?

-Networked infrastructure: Gigabit/10Gigabit, InfiniBand and storage switching and optical transport.
-Interactive services: Storage Fabric Services, computer services, security services, and application optimization services.
-Management: Fabric manager (element and network management) and Cisco VFrame (server and service provisioning).

What is the Cisco Data Centre Network Architecture based on?

Cisco Service-Oriented Network Architecture (SONA), the enterprise implementation of the Intelligent Information Network (IIN) technology vision. Cisco SONA emphasizes the value of the interactive


services provided in the networked infrastructure, such as application optimization, security, and server and storage fabric switching, to enhance business applications.

What are the benefits of the Cisco Data Centre Network Architecture (6 bullets)?

-Lower-priced server and storage infrastructure.
-Increased business agility and adaptability.
-Ability to meet regulatory compliance standards with integrated network security and support for business continuance.
-Tested and verified design and extensive service offerings for lower implementation costs and reduced risk.
-Investment protection for core data center platforms offering multiyear deployment lifecycles.
-Rapid application development and time to market of business-critical services.

Describe the evolution of the data centre (3 bullets)?

-Consolidation of the front-end data network and back-end storage network infrastructures achieves greater administrative efficiency and increases utilization, increasing return on investment and


lowering total cost of ownership.
-Virtualization increases productivity and business agility decoupling the application environment from the constraints of particular hardware. This way, computing, network, and storage resources can be


allocated to an application in a way that best meets the needs of the organization.
-Automation manages the data center as a cohesive system by facilitating easier provisioning of resources while providing faster troubleshooting and easier recovery from security threats.

What are the 4 key areas of Cisco's Data Centre Network Architecture?

-Server Fabric. Used to interconnect servers to create high-performance cluster computing.
-Storage Area/Fabric. Used to consolidate and vitualise storage resources so they can be shared more effectively.
-Data Centre Interconnect (DCI). Connects the primary DC to a backup or secondary DC over optical or traditional WAN circuits.
-Access Network. Provides secure access to employees, customers or partners connected remotely over the intranet, Internet, or extranet.

What products are associated with the Data Centre Network Architecture Server Fabric (3 bullets)?

-Cisco SFS 3000 Series Multifabric Server Switches.
-Cisco SFS 7000 Series InfiniBand Server Fabric Switches.
-Cisco Infiniband Host Channel Adapters and blade switches integrated into IBM and Dell blade servers.

What products are associated with the Data Centre Network Architecture Storage Area/Fabric (2 bullets)?

-Cisco MDS 9000 Multilayer Directors.
-Fabric switches.

What products are associated with the Data Centre Network Architecture DCI (3 bullets)?

-Cisco ONS 15302 Multiservice Customer Access Platform.
-Cisco MDS 9000 and IPS Modules.
-Cisco Catalyst 6500 Switches.

What products are associated with the Data Centre Network Architecture Access Network (2 bullets)?

-Cisco Catalyst 6500 Series/7600 Series Supervisor Engine 720-3BXL.
-Cisco VPN 3000 Series Concentrators.

What Computing and Storage resources can be found in the Networked Infrastructure Layer of the Cisco DC Network Architecture in support of SONA? (4 bullets)?

-Computing - Server Fabric.
-Computing - Catalyst Switching.
-Storage - Storage Switching.
-Storage - Optical Transport.

What Data Centre Services can be found in the Interactive Services Layer of the Cisco DC Network Architecture in support of SONA? (4 bullets)?

-DC L4-7 Switching.
-Server Fabric Services.
-DC Security.
-Storage Fabric Services.

What Application Optimisation Services can be found in the Interactive Services Layer of the Cisco DC Network Architecture in support of SONA? (4 bullets)?

-Wide area file services.
-Application velocity system.
-Application/content services.

Describe the 3 components of Cisco's Data Centre 3.0 architecture.

-Virtualisation - network and server.
-Unified Fabric - storage protocols such as FCoE and iSCSI are integrated with LAN traffic.
-Unified Computing - Intense server virtualisation with reliable connectivity between compute and storage servers.

Describe VN-Link.

VN-Link enables the tagging and distinguishing of a single VM’s traffic in a trunk.

Name a Cisco solution that can help with the optimisation of web applications.

Application Velocity System (AVS) 3100 (Formerly Fineground).

Name 4 Cisco solutions that can help with business continuity and DR.

-MDS9500 - synchronous mirroring and asynchronous replication.
-Cat6500 - xWDM and 10GB Ethernet.
-ONS 15454/15540/15530 - SAN extension solutions between DC's.
-GSS - automatic site selection.

Name a Cisco solution that can help with the consolidation of branch file servers.

-Cisco Wide Area File Services (WAFS) Core and Edge File Engines (formerly Actona and FineGround).

Name 2 Cisco solutions that can help consolidate and simplify storage management.


-Cisco MDS 9020 - fabric switch to connect and consolidate server and storage resources.
-Cisco MDS 9216 - multilayer fabric switch deployed in a core-edge architecture.

Why have the LAN and SAN historically resided on different networks (4 bullets)?

-Security – if the LAN is hacked it won’t compromise the SAN.
-Bandwidth – the SAN has always had more bandwidth, although the LAN is now catching up.
-Flow Control – the LAN will drop packets during times of congestion, before signalling the transmitter to slow down.
-Performance – it was always perceived that the SAN performs better.
