Target Operating Model: NetApp Operations with Temporal Workflows¶

This document defines the Target Operating Model (TOM) for NetApp storage operations, showcasing three operational paradigms: traditional manual operations, MCP-enabled automation, and the advanced Temporal.io-powered durable execution model.

Executive Summary¶

The Target Operating Model demonstrates the evolution from manual NetApp operations to AI-assisted automation, culminating in durable, fault-tolerant workflows powered by Temporal.io. This new paradigm ensures that complex, long-running storage operations never fail permanently and can recover from any failure without data loss or manual intervention.

    @workflow.run
    async def run(self, volume_request: VolumeRequest) -> VolumeResult:
        # Single activity execution
        return await workflow.execute_activity(
            create_volume_activity,
            volume_request,
            start_to_close_timeout=timedelta(minutes=5)
        )

@activity.defn
async def create_volume_activity(request: VolumeRequest) -> VolumeResult:
    # Call MCP server
    mcp_client = get_mcp_client()
    result = await mcp_client.call_tool("create_volume", request.dict())
    return VolumeResult.parse_obj(result)

2. Complex Multi-Step Workflow¶

@workflow.defn
class SVMEnvironmentSetup:
    @workflow.run
    async def run(self, setup_request: SVMSetupRequest) -> SVMSetupResult:
        workflow.logger.info(f"Starting SVM setup for {setup_request.team_name}")

            allocation,
            start_to_close_timeout=timedelta(minutes=10)
        )

        # Step 4: Configure networking (parallel activities)
        network_tasks = [
            workflow.execute_activity(
                create_management_lif,
                svm.uuid,

            )
        ]

        await asyncio.gather(*network_tasks)

        # Step 5: Human approval for production

                    start_to_close_timeout=timedelta(minutes=10)
                )
                raise ApplicationError("Setup not approved")

        # Step 6: Final configuration
        final_config = await workflow.execute_activity(

            svm.uuid,
            start_to_close_timeout=timedelta(minutes=15)
        )

        await workflow.execute_activity(
            send_completion_notification,
            final_config,
            start_to_close_timeout=timedelta(minutes=2)

                    id=f"expansion-{cluster_uuid}-{workflow.now()}"
                )

            # Wait for next check or external signal
            try:
                await workflow.wait_condition(
                    lambda: False,  # Never true, so always timeout
                    timeout=timedelta(hours=1)
                )
            except TimeoutError:
                continue  # Normal hourly check

            # Handle external signals
            signals = workflow.list_all_signals()
            for signal in signals:
                if signal.name == "emergency_expansion":
