Workflow Automation Technical Overview

1. Workflow Automation Technical Overview NetApp Confidential - Internal Use Only

2. Agenda • Motivation behind WFA • Where does it fit within the Orchestration picture ? • What is a Workflow ? • Customer Example • WFA Demo • Availability / Short-term Future • Questions / Comments / Feedback ?

3. The Reality of Storage Automation • Motivation • Provide an extensible platform for Flexible Automation • Encapsulate complexity into simple defined workflows that can be executed by 3rd parties with limited knowledge • Current Gaps • Each customer looks to automate processes using their own unique settings (naming standards, options, best practices) • Many storage processes require non-ONTAP configuration (VM, tickets, storage switches, etc.) • Storage teams do not have programming skill sets • Vendor based products often can’t cater for every use case

4. Storage Workflow Automation Platform • Storage Workflow • A series of steps that complete an end-to-end process • Focus on storage-centric workflows • Design • Experts use Designer GUI to create workflow • Leverage rich library of pre-defined components • Flexible platform allows for adding new components • Integrate • Publish workflow to portals & orchestration systems • Activate workflows via web services • Operate • Storage operators use portals to activate workflow

5. Audit logs & history for automation activities Monitor workflow execution Alert on activation and completion of workflow execution Identify & troubleshoot failures Support delayed execution (scheduling) One instance to support automation across multiple data centers Template/policy enforcement for process object Gold volume, Silver volume, etc. Key operational aspects

6. Workflow activation via Web Services • $wfa = New-WebServiceProxy –urihttp://localhost/wfa-ws/WorkflowService_rpc?wsdl • $jobid = $wfa.executeWorkflow(“Provison Oracle”, ("controller_A_IP=10.68.66.214", "controller_B_IP=10.68.66.217", "vCenterIP=10.68.66.132"))

9. WFA Portal Login • The operator will log into the WFA portal (http://<wfa server IP>/wfa) • Enter their UserID/Password • LDAP support available • RBAC authentication • Guest • Operator • Architect • Admin NetApp Confidential - Limited Use

10. Storage Operator Portal (example) • After successfully logging into WFA, RBAC controls will not allow the ability to Edit or change anything. The Operator will only be able to execute Workflows or review Execution statuses. • The Operator will identify a workflow to process and select ‘execute’ NetApp Confidential - Limited Use

11. Operator Inputs (per specific workflow) • The user input screen for this workflow is presented to the Operator • The Operator provides the necessary input by leveraging the default values, drop down lists, or by typing in the required values • The Operator can then elect to: • Execute now (and optionally watch the execution) • Schedule the workflow for later execution • Preview the workflow to confirm what actions will be performed NetApp Confidential - Limited Use

15. Designing a Workflow NetApp Confidential - Internal Use Only

16. Storage Architect Portal (example) • Logging into WFA as an Architect role enables the ability to design and edit workflows as well as the ‘building blocks’ leveraged by workflows. • To edit the workflow, the Architect / Storage Expert would click on ‘edit’ for the appropriate workflow NetApp Confidential - Limited Use

17. Workflow Designer NetApp Confidential - Limited Use

18. WFA concepts and building blocks • Workflow • Commands • Finders & filters • Policy templates • Functions NetApp Confidential - Limited Use

19. Storage Workflow • Definition • A series of steps that performs an end-to-end Storage process • Examples • Provisioning storage for an application (SAP, Oracle, Exchange) • Provision storage component (Gold, Silver,..) • Decommission storage for an application • Storage migration for server, application or VM • Designed by an Architect, to be executed by an Operator/administrator NetApp Confidential - Limited Use

20. Commands • Definition • An action taken as part of a workflow (excluding selection of resources) • Every workflow includes a list of commands, to be performed in order • Commands can be added by customers if written in PowerShell, Java (and later on Perl) NetApp Confidential - Limited Use

21. Commands - Examples • CreateVolume • CreateQtree (or resize existing one) • Create NFS export • Setup mount • Resize aggregate • Resize Qtree quota • Add volume to dataset • Trigger 3rd party API commands (ie VMware) NetApp Confidential - Limited Use

22. Workflow Table • A Workflow is defined by filling a table • Actions performed left to right, top to bottom • Commands appear as the columns of the table • Command’s sub-columns are the parameters required for every Command to operate • Example: NetApp Confidential - Limited Use

23. Table Cell types • Constant value • Numbers or strings that will be the same in every execution of the workflow (200, ‘TMP’ , etc) • Variable (or variable attribute) • A variable is an object that needs to be defined for the commands to operate. Examples: db_data_vol, PrimaryAggr, qtree1 • User Input • A value to be provided upon the execution of the workflow. Examples: $Appname, $dbData_volSize NetApp Confidential - Limited Use

24. Table Cell types (cont.) • Function call • Usage of function (Either pre canned or user created) on a variable or user input. Examples:NextName($Customer), CalcVolSize(Vol.size_mb) • Expression • A combination of the aforementioned types in a formulaic expression. Examples: $VolSize - 2, vol.name + “/” + qtree.name NetApp Confidential - Limited Use

25. Finders & Filters • Finder • A search operation for locating resources • The finder looks for information on WFA Objects in the WFA cached repositories • Comprised of several filtering rules that “filter out” irrelevant resources • Includes a possible sorting order for the list of applicable results • Populates a variable if a match was found • Example: “Find Aggregate, Find Array, Find volume” NetApp Confidential - Limited Use

26. Using a Finder to define a Variable Example: For locating an aggregate, we will: • Input parameters for location and required capacity • Select filters would run and filter out ill matching aggregates • Sorting order will be employed based on selected aggregate attributes • The result may be either a chosen aggregate or a decision that one was not available given the selected filtration criteria NetApp Confidential - Limited Use

27. Templates • A blueprint of object to be used as a reference or for adhering to usage policies • Examples: • Gold, silver bronze Volume • Setup object templates for fast editing NetApp Confidential - Limited Use

28. Policy templates • Policy may be used as a source for pasting information when defining a WFA object. • Any workflow attached to a policy will use the current values of policy in execution (No backward policy enforcement) • Attached policies prohibits the user from changing it’s attached attributes NetApp Confidential - Limited Use

29. Functions • A complementary tool to achieve non-trivial or black boxed operations required for planning and execution • Written in a variant of Java (Processed at run time by 3rd party library) • Examples: • Calculate volume size from actual usable size • Create a volume name following naming scheme NetApp Confidential - Limited Use
