Launching Cloud Volumes ONTAP in GCP

  • On the Canvas page, click Add Working Environment and follow the prompts.

  • Choose a Location: Select Google Cloud and Cloud Volumes ONTAP.

  • If you’re prompted, create a Connector.

  • Details & Credentials: Select a project, specify a cluster name, optionally select a Service Account, optionally add labels, and then specify credentials.

    The following table describes fields for which you might need guidance:

    FieldDescription

    Working Environment Name

    Cloud Manager uses the working environment name to name both the Cloud Volumes ONTAP system and the GCP VM instance. It also uses the name as the prefix for the predefined security group, if you select that option.

    Service Account Name

    If you plan to use data tiering or Cloud Backup with Cloud Volumes ONTAP, then you need to enable Service Account and select a service account that has the predefined Storage Admin role. Learn how to create a service account.

    Add Labels

    Labels are metadata for your GCP resources. Cloud Manager adds the labels to the Cloud Volumes ONTAP system and GCP resources associated with the system.

    You can add up to four labels from the user interface when creating a working environment, and then you can add more after its created. Note that the API does not limit you to four labels when creating a working environment.

    For information about labels, refer to Google Cloud Documentation: Labeling Resources.

    User name and password

    These are the credentials for the Cloud Volumes ONTAP cluster admin account. You can use these credentials to connect to Cloud Volumes ONTAP through System Manager or its CLI.

    Edit Project

    Select the project where you want Cloud Volumes ONTAP to reside. The default project is the project where Cloud Manager resides.

    If you don’t see any additional projects in the drop-down list, then you haven’t yet associated the Cloud Manager service account with other projects. Go to the Google Cloud console, open the IAM service, and select the project. Add the service account with the Cloud Manager role to that project. You’ll need to repeat this step for each project.

    Click Add Subscription to associate the selected credentials with a subscription.

    To create a pay-as-you-go Cloud Volumes ONTAP system, you need to select a GCP project that’s associated with a subscription to Cloud Volumes ONTAP from the GCP Marketplace.

    The following video shows how to associate a pay-as-you-go Marketplace subscription to your GCP project:

  • Services: Select the services that you want to use on this system. In order to select Cloud Backup, or to use Tiering, you must have specified the Service Account in step 3.

  • Location & Connectivity: Select a location, choose a firewall policy, and select the checkbox to confirm network connectivity to Google Cloud storage for data tiering.

  • Charging Methods and NSS Account: Specify which charging option would you like to use with this system, and then specify a NetApp Support Site account.

  • Preconfigured Packages: Select one of the packages to quickly deploy a Cloud Volumes ONTAP system, or click Create my own configuration.

    If you choose one of the packages, you only need to specify a volume and then review and approve the configuration.

  • Licensing: Change the Cloud Volumes ONTAP version as needed, select a license, and select a virtual machine type.

    A screenshot of the Licensing page. It shows the Cloud Volumes ONTAP version

    If your needs change after you launch the system, you can modify the license or virtual machine type later.

    Note If a newer Release Candidate, General Availability, or patch release is available for the selected version, then Cloud Manager updates the system to that version when creating the working environment. For example, the update occurs if you select Cloud Volumes ONTAP 9.6 RC1 and 9.6 GA is available. The update does not occur from one release to another—for example, from 9.6 to 9.7.
  • Underlying Storage Resources: Choose settings for the initial aggregate: a disk type and the size for each disk.

    The disk type is for the initial volume. You can choose a different disk type for subsequent volumes.

    The disk size is for all disks in the initial aggregate and for any additional aggregates that Cloud Manager creates when you use the simple provisioning option. You can create aggregates that use a different disk size by using the advanced allocation option.

  • Write Speed & WORM: Choose Normal or High write speed, and activate write once, read many (WORM) storage, if desired.

    Choosing a write speed is supported with single node systems only.

    WORM can’t be enabled if Cloud Backup was enabled or if data tiering was enabled.

  • Data Tiering in Google Cloud Platform: Choose whether to enable data tiering on the initial aggregate, choose a storage class for the tiered data, and then either select a service account that has the predefined Storage Admin role (required for Cloud Volumes ONTAP 9.7 or later), or select a GCP account (required for Cloud Volumes ONTAP 9.6).

    • Cloud Manager sets the service account on the Cloud Volumes ONTAP instance. This service account provides permissions for data tiering to a Google Cloud Storage bucket. Be sure to add the Connector service account as a user of the tiering service account, otherwise, you can’t select it from Cloud Manager.

    • For help with adding a GCP account, see Setting up and adding GCP accounts for data tiering with 9.6.

    • You can choose a specific volume tiering policy when you create or edit a volume.

    • If you disable data tiering, you can enable it on subsequent aggregates, but you’ll need to turn off the system and add a service account from the GCP console.

  • Create Volume: Enter details for the new volume or click Skip.

    Some of the fields in this page are self-explanatory. The following table describes fields for which you might need guidance:

    FieldDescription

    Size

    The maximum size that you can enter largely depends on whether you enable thin provisioning, which enables you to create a volume that is bigger than the physical storage currently available to it.

    Access control (for NFS only)

    An export policy defines the clients in the subnet that can access the volume. By default, Cloud Manager enters a value that provides access to all instances in the subnet.

    Permissions and Users / Groups (for CIFS only)

    These fields enable you to control the level of access to a share for users and groups (also called access control lists or ACLs). You can specify local or domain Windows users or groups, or UNIX users or groups. If you specify a domain Windows user name, you must include the user’s domain using the format domain\username.

    Snapshot Policy

    A Snapshot copy policy specifies the frequency and number of automatically created NetApp Snapshot copies. A NetApp Snapshot copy is a point-in-time file system image that has no performance impact and requires minimal storage. You can choose the default policy or none. You might choose none for transient data: for example, tempdb for Microsoft SQL Server.

    Advanced options (for NFS only)

    Select an NFS version for the volume: either NFSv3 or NFSv4.

    Initiator group and IQN (for iSCSI only)

    iSCSI storage targets are called LUNs (logical units) and are presented to hosts as standard block devices.

    Initiator groups are tables of iSCSI host node names and control which initiators have access to which LUNs.

    iSCSI targets connect to the network through standard Ethernet network adapters (NICs), TCP offload engine (TOE) cards with software initiators, converged network adapters (CNAs) or dedicated host bust adapters (HBAs) and are identified by iSCSI qualified names (IQNs).

    When you create an iSCSI volume, Cloud Manager automatically creates a LUN for you. We’ve made it simple by creating just one LUN per volume, so there’s no management involved. After you create the volume, use the IQN to connect to the LUN from your hosts.

    The following image shows the Volume page filled out for the CIFS protocol:

    Screen shot: Shows the Volume page filled out for a Cloud Volumes ONTAP instance.

  • CIFS Setup: If you chose the CIFS protocol, set up a CIFS server.

    FieldDescription

    DNS Primary and Secondary IP Address

    The IP addresses of the DNS servers that provide name resolution for the CIFS server.
    The listed DNS servers must contain the service location records (SRV) needed to locate the Active Directory LDAP servers and domain controllers for the domain that the CIFS server will join.

    Active Directory Domain to join

    The FQDN of the Active Directory (AD) domain that you want the CIFS server to join.

    Credentials authorized to join the domain

    The name and password of a Windows account with sufficient privileges to add computers to the specified Organizational Unit (OU) within the AD domain.

    CIFS server NetBIOS name

    A CIFS server name that is unique in the AD domain.

    Organizational Unit

    The organizational unit within the AD domain to associate with the CIFS server. The default is CN=Computers.

    DNS Domain

    The DNS domain for the Cloud Volumes ONTAP storage virtual machine (SVM). In most cases, the domain is the same as the AD domain.

    NTP Server

    Select Use Active Directory Domain to configure an NTP server using the Active Directory DNS. If you need to configure an NTP server using a different address, then you should use the API. See the Cloud Manager automation docs for details.

    High Availability Architecture on GCP with Cloud Volumes ONTAP

    Applications are essential to almost every business today—and when those applications fail, there can be serious impacts on the business. A key part to ensuring applications and the data they run on are always available is a high availability storage design. How can you ensure your Google Cloud storage is highly available?

    Configuring a high availability storage design in the cloud can be complex and needs to carefully balance the recovery point objective (RPO) against recovery time objective (RTO). But why not have both a low RTO and an RPO of 0?

    That’s what Cloud Volumes ONTAP High Availability (HA) for Google Cloud provides. With this out-of-the-box high availability configuration, all of the difficult design work to provide a solution that ensures access to your data, removing time lost to potential data downtime, but with a simple design, high storage efficiency, and excellent performance.

    In this blog post we’ll take a closer look at Cloud Volumes ONTAP’s high availability architecture for Google Cloud, and show how its design utilizes multiple availability zones to provide the best solution for storage high availability in cloud computing.

    What Are Highly Available Architectures?

    High availability architecture is a design goal. It is a target that you hit by designing out all possible points of failure and scenarios that could cause downtime. Architects must pay attention to every facet of the design, including network, compute, application, storage, and even monitoring and alerting systems, ensuring no single point of failure.

    The architecture of your storage should ensure that the RPO is zero; that is to say, in a failure scenario, there will be no data loss. There are many use cases that can benefit from this level of high availability: databases, media production, machine learning, and other production workloads and customer-facing applications are just some examples. Suppose there is a failure around any part of the primary storage system. In that case, the service should failover to a secondary storage system, and the RTO should be so low that the failover is seamless, and negligible to application users.

    High availability systems ensure that your application is never down. For an e-commerce site, for example, high availability means that even though the site is experiencing a failure, customers will still be able to place orders instead of looking elsewhere, protecting income and reputation. Or it could be that critical data is always available to employees or third parties using your service, keeping within SLA and meeting any legal regulations that may cover the data, again protecting income and reputation.

    Google Cloud Storage High Availability

    Google Cloud Platform offers some level of what is generally considered high availability with its Regional Persistent Disks (RPD). RPDs have primary and secondary availability zones within a region, with the disk mounted to a VM in the primary availability zone. During a zone outage, the disk is force mounted to a VM in the secondary zone; the VM could be hot standby or provisioned as part of a DR system. However, RPDs are less performant than Zonal Persistent Disks (ZPDs) with lower maximum sustained read IOPS and lower maximum sustained throughput for read and write.

    In both of these cases, hitting the enterprise-standard RPO=0 is going to be unlikely if not impossible. To achieve that level of availability, Google Cloud users can turn to NetApp Cloud Volumes ONTAP.

    The Cloud Volumes ONTAP High Availability Solution

    The Cloud Volumes ONTAP HA solution consists of a high availability cluster of two Cloud Volumes ONTAP instance groups and a mediator node, each located in a different availability zone within the same region, sharing a VPC.

    Synchronous Mirroring

    Each instance group contains a powerful compute node running ONTAP with root and boot system disks and two groups of zonal persistent disks (ZPDs). To explain the two groups of ZPDs, consider instance group A: the first group of ZPDs in instance group A make up the aggregate for the ONTAP node A, and the second group of ZPDs are virtually the aggregate for the ONTAP node B.

    All data volumes on instance A Aggr01 are synchronously mirrored to instance B Agg01, and all data volumes on Aggr02 in instance B are synchronously mirrored to Aggr02 in instance A. The synchronous mirrors ensure that all writes to a data volume must be committed to both source and destination data volumes before the write is acknowledged, guaranteeing no data loss. Synchronous mirror data flows over the high bandwidth low latency inter-availability zone links. It also keeps Cloud Volumes ONTAP in control of the data using proven existing synchronous mirror technology.

    Infographic - Cloud Volumes ONTAP Architecture HA in GCP (Multi AZ)

    The Failover Process

    The GCP Internal Load Balancer (ILM) manages connectivity to NFS and SMB services and node management services, forwarding traffic destined for a particular IP to the correct ONTAP node. If an instance group becomes unavailable, the partner ONTAP node will take over the second aggregate and provide shared services. The ILM will then forward the inaccessible node's traffic to its partner node, providing continuity of service.

    For iSCSI connectivity, multipath I/O and ALUA (Asymmetric Logical Unit Access) manage connectivity. During a zone outage, the partner node takes over the second aggregate, and ALUA ensures connectivity is maintained.

    The Failback Process

    Once the outage is resolved, and the instance group is again available, the Cloud Volumes ONTAP node must resynchronize HA volumes on its first aggregate with its partner Cloud Volumes ONTAP node’s second aggregate. As soon as the HA volumes are in sync, the synchronous mirror is recreated, and the partner Cloud Volumes ONTAP node will give back the file share services. The ILM will again forward traffic for the particular IP to the Cloud Volumes ONTAP node.

    Again, with iSCSI connectivity, the process is slightly different. Once the HA volumes are in sync, the synchronous mirror is recreated, and ALUA tells the client nodes to revert to the Cloud Volumes ONTAP node.

    Cloud Volumes ONTAP High Availability Benefits

    As we have explained above, Cloud Volumes ONTAP HA for GCP uses a multi-AZ high availability architecture design, which provides a continuation of service to applications during the complete loss of an availability zone. The ILM failover and node take over to yield an RTO to your business of fewer than 60 seconds.

    The synchronously mirrored volumes use existing, proven NetApp technology, which ensures no data loss and thus provide an RPO of 0.

    The solution comes with the standard Cloud Volumes ONTAP storage efficiency features. These include thin provisioning, data compression, deduplication, and compaction, which reduce cloud storage costs by up to 70%, which reduces I/O to the ZPDs, allowing higher overall throughput.

    Automatic storage tiering between Persistent Disk and Cloud Storage provides additional cost savings by moving unused disk data blocks to object storage when not in immediate use, and back up to the performance tier when needed.

    Conclusion

    The Cloud Volumes ONTAP high availability configuration on Google Cloud Platform provides a ready-to-go, easy-to-provision solution to the problem of storage availability.

    Cloud Volumes ONTAP’s HA configuration is a trusted feature that has been ensuring business continuity for workloads in the cloud on AWS and Azure, and on NetApp hardware for years. Now it’s ready for Google Cloud.

    A true multi-AZ solution that will keep going after the loss of an entire availability zone, only your storage admins will know something happened.

    Google Cloud projects, permissions, and accounts

    Before you can deploy Cloud Volumes ONTAP in Google Cloud, you must first deploy a Connector in a Google Cloud project. The Connector can’t be running on your premises, or in a different cloud provider.

    Two sets of permissions must be in place before you deploy a Connector directly from Cloud Manager:

    1. You need to deploy a Connector using a Google account that has permissions to launch the Connector VM instance from Cloud Manager.

    2. When deploying the Connector, you are prompted to select a service account for the VM instance. Cloud Manager gets permissions from the service account to create and manage Cloud Volumes ONTAP systems on your behalf. Permissions are provided by attaching a custom role to the service account.

    The following image depicts the permission requirements described in numbers 1 and 2 above:
