UCS Advantage: UCS Networking and Storage


I-1: Unified Fabric

Introduces the concepts of Unified Fabric within the UCS System, whereby LAN and SAN functionality run over a shared connectivity infrastructure using standard ethernet protocols for LAN and FCOE for SAN.

I-2: Easing SAN Boot Setup with UCS

Demonstrates how to use Service Profile boot policies to specify that a UCS server boot off a SAN LUN.

I-3: Adapter Templates

Shows how the definition of a UCS service profile adapter can be defined as an adapter template (containing the settings for fabric, MAC address selection, and other adapter and QOS policies).  This adapter template can be defined once and then reused within many different types of service profiles or service profile templates.

I-4: UCS Network Interface Virtualization

Covers the concepts behind the Cisco Virtual Interface Cards. Using service profiles, "virtual interfaces" are defined on these cards that are exposed to the underlying physical hardware as regular physical network interfaces.

I-5: UCS Adapter Fabric Failover

Covers the creation of UCS virtual network interfaces that are defined to use fabric failover.  UCS itself can detect outage of these virtual interfaces on a particular fabric (A or B) and automatically fail over the connectivity to another fabric.  Thus you are able to achieve connectivity high availability on a single virtual interface without have to do any configuration in the OS itself.

I-6: Extending the Network to the VM with VM-FEX

Introduces the VM-FEX feature of UCS, whereby UCS interacts with the hypervisor to form a pass-thru distributed switch to expose UCS interfaces to individual virtual machines on a 1-1 basis.

I-7: UCS Traffic Analysis for Physical and Virtual Adapters

Describes the traffic analysis features within UCS manager for server network adapters.

I-8: UCS Ethernet Switching Modes

Introduces the concepts of End-host mode (the default) and switch mode for UCS fabric interconnects.

I-9: UCS FC NPV and Switch Modes

Introduces the concepts of NPV mode (the default) and switch mode for the fibre channel and FCOE functionality of UCS .

I-10: SAN Port Channels and Trunking

Shows the creation of SAN Port Channels in UCS (multiple SAN or FCOE uplinks serving as a single channel), and VSAN Trunking in UCS (multiple VSANs traveling over the same single FC/FCOE uplink or over a SAN port channel)

I-11: Low Level Adapter Policies

Introduces the network adapter policies that can be used by the virtual networking interface definitions in a UCS service profile.

I-13: Making ISCSI Boot Simple with UCS

Shows how to configure iSCSI Boot in the UCS Managed environment.

I-16: Using VMFEX to Simplify IO in Linux KVM Deployment

Shows the configuration of the VMFEX distributed switch configuration specifically in Linux KVM hypervisor deployments.

I-17: Using VMFEX to Simplify Hyper-V Deployments

Shows the configuration of the VMFEX distributed switch configuration specifically in Microsoft Hyper-V deployments

I-19: Implementing POD-based Storage with Full Zoning

Shows how to attach SAN storage directly to UCS Fabric Interconnects for the specific use of the servers within that UCS.   This feature is typically used with the UCS zoning feature, whereby UCS (in FC switch mode) can dynamically create zone sets and zones based on WWN's of service profiles that are defined to use the storage.

I-20: Organization-based VLAN Usage

Shows UCS newer VLAN multi-tenancy feature, whereby VLANs can be restricted to specific organizations.

I-21: Using IO Templates and Connectivity Policies

Shows the creation, use and relationship between vnic / vhba templates and Network/Storage Connectivity policies (which are templates for a full collection of vnic/vhba)

I-22: Converging Infrastructure with Multi-Hop FCOE

Covers configuration of the northbound FCOE feature in UCS, whereby fibre channel traffic travels out of the UCS fabric interconnects into the Nexus / MDS switch northbound using FCOE rather than physical fibre.

I-23: UCS Network Optimization

UCS Network optimization using policies / profiles / templates.

I-27: Provisioning Efficiencies

Covers provisioning efficiencies for network and storage using policies / profiles / templates.
