Schedule May/June
Date (cal. entry) Topic Abstract and Takeaway Programming Language 15.05.2012
22.05.2012
29.05.2012
Date (cal. entry) NetApp Powershell Toolkit Intro This session is an introduction to the NetApp Powershell Toolkit. It show the feature richness and the simplicity of use. You learn how to install the toolkit, connect to controllers and get an overview on its features.
SDK Introduction This session is an introduction to the NetApp Manageability SDK in its latest NetApp Manageability release. You learn the coverage to the SDK and get an overview on its features. You learn how to install it and start rapid prototyping with automatic code generation.
Use Case: Automated Snapshot Archiving using APIs This session is about automated snapshot archiving leveraging NetApp APIs. You learn how to organize snapshot archives from different sources.
Powershell Various Perl Topic Abstract and Takeaway Programming Language 05.06.2012
Introduction into Automating Cisco UCS This session is an introduction to the Cisco UCSPS library to automate Cisco UCS components in a FlexPod. You learn how to install, connect and use basic commandlets.
Powershell 12.06.2012
Use Case: Performance Advisor Data Extraction This session is about extracting performance data of the storage infrastructure and making it available in structured SQL database for further processing. You learn how to parse performance data and extract relevant counters.
Perl 19.06.2012
Use Case: Creating VLANs on Cisco UCS Within this session the Cisco UCSPS library is used to create VLANs according to the specification of the FlexPod reference architecture. You learn how to query for existing VLANs, define new VLANs and register them in a VLAN template.
Powershell 26.06.201
2 Use Case: DB This session is about a backup workflow for a database which includes a verification Backup Workflow with phase before treating the backup as valid. You learn the basic structure of a backup Perl DB Verification workflow and how to embed any postprocessing steps.

Session Takeaway
Get familiar with: – Creating VLANs – Creating VNIC templates – Creating Service Profile templates Navigate in sample Flexpod Provisioning Scripts and start to innovate NetApp Confidential - Internal Use Only

VLANs
Create a VLAN in UCSM NetApp Confidential - Internal Use Only

VLANs in FlexPod Stack
Implementing different trust domains: – Storage: vfiler – Network: VLANs Multiple VLANs defined for infrastructure (see implementation guide) VLANs for customer, each customer gets e.g.: – Frontend VLAN: Access to the hosted services – Storage VLAN: Access to storage – Management VLAN NetApp Confidential - Internal Use Only

VLANs in the entire Stack
U Po13 U Po14 INPUT: vlan.id/.descr
PRE: Po10-Po14 exist, vlan.id does not exist on all Po10-Po14 POST: vlan.id enabled from storage (S) to Ucs (U).
INFO: storage vlan needs to be enabled everywhere. E.g. frontentaccess would only go on Po10,13,14 N Po10 N Po11 S Po12 S For left and right
