1 Technical Report Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP 8.3 Eric Wagar, NetApp June 2015 TR-4400 Abstract NetApp technology enables data centers to extend their virtual infrastructures to include the benefits of advanced storage virtualization. NetApp leads the storage industry with an information platform that is hardware agnostic and that can aggregate disparate forms of hardware together and virtualize access to storage; in effect, a platform that functions as a storage hypervisor. NetApp clustered Data ONTAP technology is the cornerstone of the storage hypervisor. This document aligns the storage hypervisor with the server hypervisor by prescribing best practices for deploying VMware vsphere 6.0 on clustered Data ONTAP 8.3 storage by using VMware vsphere Virtual Volumes.

4 1 Solution Overview Server virtualization continues to be a transforming force in IT, and VMware vsphere has been at the leading edge of this evolution. The pace of new announced products and released updates has been rapid and significant. VMware vsphere 6.0 has expanded its capabilities in the areas of networking, virtual machine (VM) management, and storage. vsphere Virtual Volumes (VVOLs) is one such new storage feature. NetApp has been at the forefront of this technology since it was announced by VMware, helping to provide architectural input to the design as a design partner. Before the release of VVOLs, storage administrators and virtual infrastructure (VI) administrators had separate environments with disparate management methodologies. The separation resulted in long planning cycles to refine the storage environments needed by VI administrators. The lack of granularity in the ability to manage storage at the per-vm level offered no guarantee that VI administrators would use the correct datastore for each VM. VVOLs allow storage administrators to configure storage volumes and easily communicate storage capabilities to VI administrators. VI administrators, in turn, assign VM storage policies to those volumes. These policies allow VI administrators to manage VMs in a more consistent, effective, and efficient way. More importantly, they reduce time to deployment because the communication between storage administrators and VI administrators is streamlined. This technical report explains fundamental VVOL concepts. It includes sample methodologies for configuring and deploying the software required to make VVOLs work with NetApp FAS storage systems, and it highlights important best practices. NetApp encourages you to follow these best practices as much as possible to maximize performance, simplicity, and reliability when deploying a VVOL environment. 1.1 Target Audience The deployment instructions in this report assume that the audience has a working knowledge of VMware vsphere 5 or earlier versions, including how to deploy OVF or OVA files, create VMs, mount ISO images as a CD/DVD for a VM, and similar tasks. The instructions also assume a working knowledge of the NetApp clustered Data ONTAP software. Some deployment steps are omitted, but steps that vary from normal procedures are explicitly explained. 1.2 VVOL Concepts VVOLs and related components are the building blocks for VM granular management. The fundamental goal of the technology is to separate the management of storage from the management of VMs so that the required knowledge and understanding for the two technology areas can be better focalized. Before the addition of VVOLs to vsphere, administrators with an understanding of storage had to explain to VI administrators who did not specialize in storage-related tasks how to identify the datastores to use for specific classes of VMs or for component virtual disks and other objects that consume storage. They tried to achieve that objective through some combination of documentation and conventions for datastore naming. However, consistency, compliance, and verification were difficult to maintain and enforce. VM Storage Policies VM storage policies constitute one of the key elements of the VVOL solution. These policies existed in versions of vsphere earlier than vsphere 6.0, but they lacked the sophistication to query the storage for the capabilities to include in rule sets. Consequently, capabilities could be advertised only as a single string. VMware APIs for Storage Awareness (VASA) 2.0 provides the technology to query storage and return a set of storage capabilities to vcenter. VASA vendor providers supply the translation between the storage system APIs and constructs and the VMware APIs that vcenter understands. In the NetApp implementation, the VASA vendor provider is NetApp VASA Provider 6.0 for Clustered Data ONTAP, an 4 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc.

5 appliance VM that is deployed to vcenter from an OVA file. VASA Provider is managed through pages and context-sensitive menus in the NetApp Virtual Storage Console for VMware vsphere (VSC) plug-in. VASA Provider presents the set of capabilities of the storage array or of an object in the array to vcenter. The capabilities include features such as availability, performance, capacity, space efficiency, replication, and protocol. Support for a capability might require specific hardware, licenses, or configuration. A set of capabilities for a volume or a set of volumes is called a storage capability profile (SCP). Storage administrators use VSC to create and manage SCPs. Storage for VMs that use VVOLs is provisioned through VM storage policies. The VI administrator creates VM storage policies to define the storage requirements for the VMs and then maps NetApp storage capabilities to one or more VM storage policies. Capabilities can be mapped to VM storage policies as an SCP, as individual capabilities, or as both. If both mapping methods are used, the individual capability selected in the VM storage policy overrides the capability selected in the SCP. For example, if a VM storage policy includes both an SCP that requires deduplication and a separate deduplication capability with the setting No, the resulting VM storage policy requires a NetApp FlexVol volume without deduplication. The Create VM Storage Policy wizard lists the storage objects that are compatible and incompatible with the VM storage policy after the VI administrator selects capabilities and/or a profile to add to the policy. Table 1 summarizes the NetApp storage capabilities that are supported by VVOLs. Table 1) NetApp storage supported capabilities.

For example, they can be created using NetApp OnCommand System Manager. VVOL Datastores Traditional datastores are either Virtual Machine File Systems (VMFSs) created on LUNs or storage controller file systems presented as NFS mounts. Within these datastores, each VM has a directory that contains a set of files: virtual disks, which are large files containing a disk image, and other files such as VM swap files, configuration files, and logs. In the NetApp implementation of VVOLs, a VVOL datastore consists of one or more FlexVol volumes within a storage container (displayed as backing storage ). A storage container is simply a set of FlexVol volumes used for VVOL datastores. All FlexVol volumes in a storage container must be accessed through the same protocol (NFS, iscsi, or FC) and must be owned by the same SVM, but they can be hosted on different aggregates and nodes of the NetApp cluster. FlexVol volumes can be created outside of the VSC workflows or through the new VVOL Datastore wizard. However, all LUNs and other VVOL-related objects are created and managed by VASA Provider. A VVOL is either a LUN used with block protocols or a file or directory used with NFS. A VVOL LUN is not mapped ( masked, in common SAN terminology) to storage in the sense that traditional LUNs are. Table 2 lists the different types of VVOLs and describes how they are implemented. Table 2) VVOL types and implementation. VVOL Type Block Implementation NFS Implementation Notes or Examples Configuration LUN, 4GB Directory containing configuration files and pointers to other VVOLs Contains VMX, NVRAM, logs, VMDK descriptors, and VMware snapshot descriptors.

7 VVOL Type Block Implementation NFS Implementation Notes or Examples Other Depends on use case Depends on use case VMware HA datastore heartbeat information (4GB LUN or NFS directory) * Technically, the swap VVOL is the size of the VM memory minus any VM memory reservation. Protocol Endpoints The I/O path to a VVOL travels through a new storage object called a protocol endpoint (PE). VVOL LUNs are bound to a specific PE through a binding call that is managed by VASA Provider. VASA Provider determines which PE is on the same node as the FlexVol volume that contains the VVOL and binds the VVOL to that PE. VVOLs are bound to a PE when they are accessed by a VMware ESXi server. The most common form of access is powering on the VM. The blue lines in the command block in Figure 1 show the binding relationship between a VVOL and the PE LUN through which the ESXi server accesses that VVOL. Figure 1) Binding relationship between a PE LUN and a VVOL. Vserver Name: WestPac_a_iSCSI PE MSID: PE Vdisk ID: d f1b9a VVol MSID: VVol Vdisk ID: d e193fe3b7 Vserver UUID: 4fe2e2b0-7cd8-11e4-b968-00a0983d22b6 Protocol Endpoint: /vol/netapp_iscsi_vvol_flexvol/vvolpe PE UUID: 047d0366-ee7b-4bcf-9cdc-99cecc PE Node: alpha-01 VVol: /vol/netapp_iscsi_vvol_flexvol/naa.600a d24464f vmdk VVol Node: alpha-01 VVol UUID: 534dc4ff-116c-47bb d27f97370cb Secondary LUN: d2249d Optimal binding: true Reference Count: 1 Best Practice Perform the VVOL workflows through VSC to remove the need to create PEs manually. For block protocols, a PE is a small (4MB) LUN. VASA Provider creates one PE in each FlexVol volume that is part of a VVOL datastore, as shown in Figure 2. PEs are mapped to initiator groups that are created and managed by VASA Provider. Best Practice LUN PEs are mapped using LUN IDs 300 and higher. Ensure that the advanced option Disk.MaxLUN allows a LUN ID number that is higher than 300 (the default is 1,024). 7 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc.

VASA Provider creates PEs when the first VVOL datastore is created on the SVM by using a specific protocol. VASA Provider also creates export policy rules automatically.

9 1.3 Solution Technology In the NetApp solution described in this technical report, the core enabling component for VVOLs is VASA Provider. It communicates with vcenter by using VASA APIs and with clustered Data ONTAP by using the APIs in the NetApp Manageability SDK. Figure 4 shows the technical components of the solution. Figure 4) vcenter, VSC, VASA Provider, ESXi servers, and clustered Data ONTAP storage. VASA Provider is deployed as an OVA file and is managed through the VSC plug-in in the vsphere Web Client. The administrator manages VASA and VVOLs through the Web Client. Best Practice Do not install or migrate VASA Provider, vcenter Server (appliance or Windows-based), or VSC onto a VVOL datastore. Because of the circular nature of VVOLs, moving these critical infrastructure items to a VVOL makes them inaccessible during a catastrophic event such as a power outage. 1.4 Use Case Summary This solution applies to the following uses cases: Deploying VVOLs with NetApp clustered Data ONTAP on NFS Deploying VVOLs with NetApp clustered Data ONTAP on iscsi Deploying VVOLs with NetApp clustered Data ONTAP on FC 1.5 VVOL Limitations For the NFS protocol, vsphere 6.0 supports VVOLs only with NFS version 3. 2 Technology Requirements The deployment of VVOLs on clustered Data ONTAP storage requires several hardware and software components. 9 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc.

Hardware Servers that support vsphere 6.0 NetApp cluster that supports clustered Data ONTAP 8.3 or later Networking hardware (switches, HBAs, NICs, and so on) to support the selected protocol Quantity 1 minimum, 2 preferred for HA purposes 1 cluster, with a minimum of 1 HA pair Varies depending on the specific deployment 2.2 Software Requirements Table 4 lists the software components required to run VVOLs on clustered Data ONTAP. The procedures documented in this report might apply to later versions of the listed software, but some steps are likely to change. For example, some manual steps might become part of a wizard or workflow. Table 4) VVOLs on clustered Data ONTAP software requirements. Software Version or Other Information NetApp clustered Data ONTAP 8.3 or later (minimum supported is version 8.2.2) VMware vsphere 6.0 or later NetApp Virtual Storage Console (VSC) running on Windows Server 2008 or 2012 NetApp VASA Provider for Clustered Data ONTAP Initial Setup The VVOL solution assumes that you have deployed a clustered Data ONTAP storage system. Setting up VVOLs on NetApp storage involves the following tasks: Configuring and testing DNS entries for vcenter Server, VASA Provider, and the Windows Server host running VSC Configuring time services for all components of the solution Creating and configuring an SVM for VVOL use Configuring the storage protocol Deploying physical servers and installing ESXi 6.0 Deploying vcsa 6.0 Deploying VSC and VASA Provider: Creating or cloning a Windows Server VM Installing VSC in the Windows Server VM Deploying NetApp VASA Provider Adding the storage system to VSC 10 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.

11 3.1 Configure and Test DNS Entries Specific steps for configuring DNS entries for your environment depend on your installed infrastructure. In any case, the following entities must have correctly configured DNS entries, and the host names used when you deploy these entities must match the DNS entries: vcenter Server 6.0 (vcsa or Windows-based) NetApp VASA Provider appliance Windows Server host running VSC The following entities should have DNS entries, but if they do not have them, VVOLs might still work: ESXi servers Clustered Data ONTAP cluster-management LIF and node-management LIF SVM management LIFs Note: SVM data LIFs do not require DNS entries, especially if they are on a separate private storage network. You can use Table 5 to notate the DNS and IP address entries for the suggested list of entities in the first column. Depending on the number of nodes in your Data ONTAP cluster and on the protocols that you are using, some of these entities might not be needed in your configuration. NFS and iscsi require separate LIFs with their own IP addresses because clustered Data ONTAP allows NFS LIFs to move and fail over, but not iscsi LIFs. Table 5) Entity DNS and IP address list.

Ensure that each device or VM is configured to use the same time server. 3.3 Create and Configure an SVM for VVOL Use You must create and configure an SVM to contain all FlexVol volumes in a VVOL datastore. Create the SVM You can use either OnCommand System Manager or the clustered Data ONTAP CLI to create an SVM for VVOL use. OnCommand System Manager For instructions on how to use the wizards in OnCommand System Manager to create the SVM, see the OnCommand System Manager documentation library on the NetApp Support site. Clustered Data ONTAP CLI For instructions on how to use the clustered Data ONTAP CLI to create the SVM, see the Data ONTAP 8 documentation library in the NetApp Support site. Configure NDMP on the SVM After you create the SVM, disable node-scoped NDMP mode and enable NDMP on the SVM: 1. Run the following commands: cluster::> system services ndmp node-scope-mode off NDMP node-scope-mode is disabled. cluster::> vserver modify -vserver <svm> -allowed-protocols fcp,ndmp cluster::> vserver services ndmp on -vserver <svm> Important Disabling node-scoped NDMP mode is a one-time task per cluster. Ensure that you include all protocols to be used with the solution in the allowed protocols list of the vserver modify command. 3.4 Configure the Storage Protocol You have a choice of storage protocols to use with the NetApp VVOL solution. 12 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc.

13 Best Practice Create a LIF per node per fabric (NFS, FC/FCoE, or iscsi) for each protocol to be used for VVOLs. It is not necessary to create a LIF per datastore or per FlexVol volume. NFS To prepare for VVOLs over NFS, ensure that you have a data LIF per node for the SVM that supports VVOLs. The data LIFs must have a home port on the network that connects the ESXi server to the storage. iscsi and NFS LIFs must be separate, but they can coexist on the same network and physical port, interface group, or VLAN. If you did not create an NFS service on your SVM when you created the SVM, complete the following steps to set it up: 1. Create and configure ESXi NFS VMkernel ports on the same network, VLAN, and subnet as the SVM target LIFs. 2. Optional: Create volumes manually. However, NetApp strongly recommends that you manage VVOLs through VSC. Note: Best Practice You do not need to manage export policies because VASA Provider manages them automatically. Whenever possible, use VSC to perform the VVOL workflows. iscsi To prepare for VVOLs over iscsi, ensure that you have a data LIF per node for the SVM that supports VVOLs. The data LIFs must have a home port on the network that connects the ESXi server to the storage. iscsi and NFS LIFs must be separate, but they can coexist on the same network and physical port, interface group, or VLAN. To create an iscsi service on your SVM, complete the following step: 1. Create and configure ESXi iscsi VMkernel ports on the same network, VLAN, and subnet as the SVM target LIFs. FC To prepare for VVOLs over FC, ensure that you have a data LIF per node per fabric for the SVM that supports VVOLs. For example, if you have two nodes and typical dual redundant SAN fabrics, you should have four FC target LIFs in the SVM, each homed on a different physical FC target port. To create an FC service on your SVM, complete the following step: 1. Apply all zoning rules and practices to the FC network. Use soft zoning to specify the target WWPN of the SVM LIFs and not the physical ports of the nodes. 3.5 Deploy Physical Servers and Install ESXi 6.0 Instructions for installing physical server hardware are out of the scope of this document. To install ESXi, follow the steps in the vsphere 6.0 Installation and Setup guide. ESXi has no special requirements for use with VVOLs other than the appropriate networking and/or SAN configuration. 13 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.

14 Best Practice To install ESXi, NetApp recommends that you follow the instructions and recommendations in the latest version of the VMware vsphere on NetApp Clustered Data ONTAP technical report. 3.6 Deploy vcsa 6.0 VMware has changed the installation instructions of vcenter Server Appliance (vcsa) to include a vcenter Server Appliance installer, which is distributed as an ISO image. For instructions on how to install vcsa, see chapter 9 of the vsphere 6.0 Installation and Setup guide. 3.7 Deploy VSC and VASA Provider To deploy VSC and VASA Provider, you must create a Windows Server VM for VSC, install and configure both applications, and then add your storage system to VSC. Create or Clone a Windows Server VM for VSC The exact steps for creating a Windows Server VM for Virtual Storage Console (VSC) depend on your environment. The VSC server can be physical or virtual. Verify that the Windows Server VM is genuine and properly activated. Verify that your firewall settings allow VSC, VASA Provider, and vcenter traffic. VASA Provider menus will not be displayed in VSC until the application is deployed and configured as described in the section Deploy VASA Provider for Clustered Data ONTAP. Install and Configure VSC To install and configure VSC, refer to the following documentation: For an overview of VSC and information about how to download the software, see the VSC 6.0 download page. For information about role-based access control (RBAC), see the VSC 6.0 documentation library on the NetApp Support site. For information about the RBAC User Creator tool, see the RBAC User Creator for Data ONTAP community site. Deploy VASA Provider for Clustered Data ONTAP You deploy the VASA Provider for Clustered Data ONTAP virtual appliance on an ESXi host. After VASA Provider is installed, you must register it with VSC. Best Practice Do not install or migrate VASA Provider, vcenter Server (appliance or Windows based), or VSC onto a VVOL datastore. Because of the circular nature of VVOLs, moving these critical infrastructure items to a VVOL makes them inaccessible during a catastrophic event such as a power outage. To deploy VASA Provider, complete the following steps: 14 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.

15 1. In the vsphere Web Client inventory lists, right-click a data center, cluster, or specific ESXi server and select Deploy OVF Template. 2.

If you have not already been forced to, log out of the vsphere Web Client. 22. Log back in as a vsphere Web Client administrator to load the VASA Provider menus and workflows. Note: Best Practice For more information about how to install VASA Provider, see the VASA Provider for Clustered Data ONTAP User's Guide. Back up the VASA Provider VM regularly. At a minimum, create hourly NetApp Snapshot copies of the traditional datastore that contains VASA Provider. For more information, see NetApp KB Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.

24 Add the Storage System to VSC After you install VSC and VASA Provider, you must add the storage system to VSC. To do so, complete the following steps: 1. From the vsphere Web Client homepage, select Virtual Storage Console > Storage Systems. 2. Under Objects, click the green plus-sign icon. 3. Enter the cluster management IP address or host name, admin for the user name, and the password that you specified for the admin account. Click OK. 4. Review the allowed privileges and click OK. 4 Storage Capability Profiles and VM Storage Policies VASA Provider allows you to create storage capability profiles (SCPs) and map them to VM storage policies. SCPs help you maintain consistency across the storage. You can also use VASA Provider to check for compliance between the storage and the SCPs. 4.1 Enable VM Storage Policies in ESXi Servers or the Cluster VVOLs and storage policy based management of storage are automatically enabled in the cluster. 4.2 Create SCPs SCPs can be created in the following ways: From default SCPs that are installed with VASA Provider 24 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.

25 From scratch By cloning another SCP Automatically by reference to existing traditional datastores on clustered Data ONTAP To create a new SCP from scratch, complete the following steps: 1. On the vsphere Web Client homepage, select Virtual Storage Console > VASA Provider for Clustered Data ONTAP > Storage Capability Profiles. 2. Click the green plus icon. 3. Give the SCP a name and click Next. 4. For each capability category, make the appropriate selections and then click Next: Yes means that the capability is required in this profile. No means that the capability is forbidden in this profile. Any means that the capability is optional in this profile. Note: See Table 1 for a complete list of SCP options. 5. Review the summary of capability selections and click Finish. 25 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.

26 4.3 Create a VM Storage Policy and Map It to the SCP To create a VM storage policy and map it to the SCP, complete the following steps: 1. On the vsphere Web Client homepage, click VM Storage Policies. 2. Click the new VM storage policy icon (green plus icon with a scroll). 3. Give the VM storage policy a name and click Next. 4. On the Rule-Sets page, click Next. 5. On the Rule-Set 1 page, make the following selections: a. From the Rules Based on Data Services drop-down list, select NetApp.Clustered.Data.ONTAP.VP.vvol. b. Under the Add Rule drop-down list, select Profile Name. Note: VI administrators can build a VM storage policy from individual capabilities or add capabilities that were selected as Any in the SCP, but the best practice is to use the SCPs as they were created by the storage administrator. 26 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.

27 6. Select an SCP from the list that is displayed to the right of Profile Name and click Next. 7. Review the compatible and incompatible storage to verify that you have storage that is compliant with the VM storage policy. Note: If no compatible storage is available, you can configure compatible storage by following the instructions in the section VVOL Datastores. 8. After you review the available storage, click Next. 9. Review the settings for the VM storage policy and click Finish. 5 VVOL Datastores You do not need to create a VVOL datastore for each FlexVol volume that will be used for VVOLs. In most cases, using a single datastore is the simplest solution even if the datastore includes FlexVol volumes that have different capabilities. The VVOL technology excels in this area because a single VVOL datastore can contain multiple underlying FlexVol volumes with different capabilities. VM storage policy based management applies the correct policy and subsequently places the VM in the correct underlying volume. Important Do not use the built-in vcenter New Datastore wizard to provision NetApp VVOL datastores. The NetApp workflow performs all of the required storage-side setup, such as creating export policies, initiator groups, and LUN mappings. You can perform these steps manually and then use the vcenter New Datastore wizard to provision the VVOL datastores, but the manual process is more error prone. 5.1 Create a VVOL Datastore To create a VVOL datastore and add FlexVol volumes to it, complete the following steps: 27 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc.

Repeat step 5 to create additional volumes as part of this VVOL datastore. 7. On the Provision FlexVol page, click Next. 8. Review the storage settings for the VVOL datastore and click Finish. 6 VM Management The VM management tasks in a VVOL solution include using VM storage policies to create VMs with VVOLs and migrating VMs to VVOLs. Best Practice When you create SCPs and VM storage policies, check the compliant datastore list to verify that at least one datastore can support the policy. This measure will help you troubleshoot issues between the VI administrator and the storage administrator. 6.1 Create VMs with VVOLs Using VM Storage Policies To create a VM with VVOLs, complete the following steps: 1. From the vsphere Web Client homepage, click Inventory Trees and select the Hosts and Clusters view. 2. Right-click a cluster or host and select New Virtual Machine. 3. Select Create a New Virtual Machine and click Next. 32 Applying VMware vsphere Virtual Volumes on NetApp Clustered Data ONTAP NetApp, Inc. All rights reserved.
