15.05.2012 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.

Powershell

22.05.2012 NetApp Manageability SDK Introduction

This session is an introduction to the NetApp Manageability SDK in its latest 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.

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

26.06.2012 Use Case: DB Backup Workflow with DB Verification

This session is about a backup workflow for a database which includes a verification phase before treating the backup as valid. You learn the basic structure of a backup 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

VLANs

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
