Welcome to Data ONTAP 8.2.1 New Features. In this course, you learn about the new features that Data ONTAP 8.2.1 provides for you and for all NetApp customers who use clustered Data ONTAP and Data ONTAP operating in 7-Mode .


The features that are introduced in Data ONTAP 8.2.1 enhance the benefits that are provided by clustered NetAppsolutions. These benefits include nondisruptive operations, proven efficiency, and seamless scalability. The 8.2.1 release also introduces features that enhance cluster security and manageability.

Among the exciting new features that are available in Data ONTAP 8.2.1 are nondisruptive shelf removal, offboxantivirus scanning, the Automated Workload Analyzer tool, Clustered Data ONTAP Edge, and increased fan-in limits for data replication.

Many of the features that are available in clustered Data ONTAP 8.2.1 are also available in Data ONTAP 8.2.1 operating in 7-Mode. And, exclusively for 7-Mode, new hardware options are available for MetroCluster.


Throughout this course, look for these clustered Data ONTAP and Data ONTAP 7-Mode icons to represent which operating modes benefit from each new 8.2.1 feature.


This lesson focuses on the new Data ONTAP features and processes that enable and facilitate nondisruptiveoperations (NDO).


Storage Enclosure Services (SES) v2 is included within Data ONTAP 8.2.1. SES supports the hot removal of qualified storage shelves from the top, middle, and bottom of the stack. The removal can occur as the node is serving data. The shelf can be detached from the loop without disruption to the remaining storage. Multipath high availability (MPHA) or dual-path cabling is required. SES provides continuous data access while you dynamically assign, promote, and retire storage shelves.

To remove a shelf without disruption, you can use the volume move feature to vacate data from any aggregate that uses the disks on the shelf that is to be removed. Data aggregates can then be taken offline and deleted. You can also use the storage disk replace command to initiate a RAID copy of the disks on the shelf that is to be removed. Use the disk replace command to move the root aggregate (aggr0) of the node to other shelves. Finally, remove ownership from the disks and remove the shelf from the stack.

Nondisruptive shelf removal is supported in both clustered Data ONTAP 8.2.1 and Data ONTAP 8.2.1 operating in 7-Mode.


With clustered Data ONTAP 8.2, NetApp offered support for continuously available SMB shares for Hyper-V. With clustered Data ONTAP 8.2.1, support is extended to SQL Server 2012 implementations. Now, nondisruptiveoperations (NDO) are provided for SQL Server systems and for user databases in a NAS environment, and storage provisioning and management are simplified. SMB 3.0 features such as witness protocol, ODX copy offload, and remote VSS are leveraged.

To enable continuously available shares, you enter advanced privilege mode in the cluster shell, enable the SMB3 protocol on the CIFS server of your storage virtual machine (SVM), and then enable the continuously-available property on any share that will host SQL databases.

The term storage virtual machine is a replacement for the term virtual storage server, and the acronym SVM is a replacement for the abbreviation Vserver. Throughout the rest of this course, the acronym SVM is used.

Clustered Data ONTAP does not natively support SQL Server database snapshots on an SMB share. To enable the use of SQL Server snapshots, the snapshot file must reside on block storage. For more detail, see knowledgebase article 2017128.


The new offbox antivirus feature supports on-access virus scanning for clients that use the CIFS protocol to access data on the cluster. The feature supports multiple parallel AV scanners for improved scalability, high availability, and performance. In-memory caching of successfully scanned data avoids redundant scanning and thus improves performance. Supported vendors include McAfee and TrendMicro. Support for Symantec antivirus is scheduled to be available in the first quarter of calendar year 2014. For more information about this feature, see the Clustered Data ONTAP Antivirus Configuration Guide.


This lesson focuses on the new Data ONTAP features and processes that enhance the proven efficiency that NetAppsolutions provide.


Automated Workload Analyzer (AWA) is a valuable tool that you can use to estimate the optimal size of your workloads Flash Pool cache. AWA is enabled on an aggregate. It analyzes your workload in real time to estimate the recommended size of the Flash Pool cache and to predict cache hit rates. It recognizes workload characteristics and uses read/write offload and overwrite statistics to determine whether the workload is cacheable.

AWA is available in both clustered Data ONTAP 8.2.1 and Data ONTAP 8.2.1 operating in 7-Mode. In 7-Mode, AWA is invoked by using an advanced privilege level command. in clustered Data ONTAP, AWA is available via the node shell. The AWA tool can be used on both Flash Pool aggregates and HDD-only aggregates. It can also be used on any controller on which a Flash Cache module is installed.


Many customers require a small-footprint storage solution to service their remote or back offices. The solution needs to meet multiple requirements. It should leverage server-virtualization technology. It should integrate with the enterprise storage solution that is available in the customers data center. It should provide superior storage efficiency and central management for backup and disaster recovery. It should increase staff productivity by enabling remote office employees to concentrate on critical business operations, rather than on managing and backing up local storage.

Clustered Data ONTAP Edge is a single-node Data ONTAP cluster that runs in a VMware hypervisor. It is not a dedicated FAS or V-Series storage controller. It serves as a mirror and vault destination for a Data ONTAP cluster that is located in the data center. It supports replication and efficiency features such as Snapshot, FlexClone, SnapVault, SnapMirror, and deduplication. It also provides flexibility by running on a variety of leading serversfrom HP, IBM, Dell, Cisco, and Fujitsu.

Clustered Data ONTAP Edge extends Data ONTAP from core to edge.


When clustered Data ONTAP 8.1 installations are upgraded to clustered Data ONTAP 8.2, SnapMirror relationships are not automatically upgraded, because the relationships within the two releases use different syntax. After the upgrade, the relationships are operational but limited. They can take advantage of the enhancements and scalability improvements that the 8.2 release provides only after they are manually broken and re-created.

With clustered Data ONTAP 8.2.1, a relationship that was created on an 8.1 cluster is automatically updated to the 8.2 format, provided that three conditions are met: The source and destination SVMs are peered or are in the same SVM. The node that owns the aggregate that contains the destination volume is running clustered Data ONTAP 8.2.1 or

later. The node that owns the aggregate that contains the source volume is running clustered Data ONTAP 8.2 or later.

OnCommand Workflow Automation 2.2 and Data ONTAP 8.2.1 are scheduled to be released at approximately the same time.

Workflow Automation 2.2 includes several new features. The volume move command automates the steps that are required to refresh hardware. The configuration of Infinite Volume storage classes is simplified and automated.


System Setup is an easy-to-use graphical utility. Previously, it was available only on entry-level platforms. However, System Setup 2.3 is now available on the storage FAS3200 series platforms. System Setup includes cluster interconnect support and validation for switched and switchless two-node clusters and for single-node clusters.

Previous versions of System Setup install only the base cluster license. The customer was required to install additional licenses after setup was complete. The new version allows installation of all licenses during the initial setup. System Setup 2.3 also provides improved disk-provisioning rules to help customers follow best practices for performance and reliability.


This lesson focuses on the new Data ONTAP features and processes that enable Data ONTAP to scale seamlessly.


Before clustered Data ONTAP 8.2.1, you could assign an export policy only at the volume level. An export policy that was assigned to a parent volume applied to all of the qtrees in the volume. Now, you can export a qtree by applying an export policy directly to the qtree. Direct assignment enhances scalability by extending the number of exports beyond the volume limits per node or per cluster. Assignment of an export policy to a qtree is not required. If no export policy is assigned, the export defaults to the policy that is associated with the parent volume. Currently, qtree exports are supported only with NFS version 3.


When you use the 1.2 release of the 7-Mode Transition Tool to migrate from Data ONTAP operating in 7-Mode to clustered Data ONTAP, qtree exports are maintained across the migration. Because the exports are maintained, the migration process is simplified.

Because advanced features such as replication, data mobility, and storage quality of service are available only at the volume level, NetApp recommends that customers migrate the data that is stored within qtrees to individual volumes.


In a fan-in configuration, source SVMs on multiple source clusters have SnapMirror or SnapVault relationships with destination SVMs on one destination cluster. Source and destination SVMs can be on the same cluster or on different clusters.

The fan-in ratio is limited, because a cluster can have only so many cluster-peer relationships. In clustered DataONTAP 8.2, the fan-in limit is 7. In clustered Data ONTAP 8.2.1, the limit is 63. This dramatic change increases data-protection flexibility and scalability.


Starting with clustered Data ONTAP 8.2.1 control of the speed of a SnapMirror transfer, called throttling, includes relationships within a cluster. With previous releases, the control applied only to SnapMirrorrelationships for intercluster peers. If the throttle option is specified when the relationship is created, all transfers for that relationship will observe the specified throttle value.

Before clustered Data ONTAP 8.2.1, an upgrade from 32-bit aggregates to 64-bit aggregates required the addition of disks. The additional disks enabled the size of the aggregate to increase beyond the 32-bit limit. With clustered Data ONTAP 8.2.1, you can use the storage aggregate 64bit-upgrade start cluster shell command to induce the conversion. After you convert to the 64-bit format, you can use the Data ONTAP features that require 64-bit aggregates, such as compression, Flash Pool aggregates, and deduplication-aware and compression-aware SnapVault backups.

For the FAS3220 and FAS3250 platforms and for the FAS6200 and the FAS8000 series platforms, NetApp now supports 16-Gb FC-VI adapters on MetroCluster configurations.

NetApp supports stretch MetroCluster up to a distance of 500 meters. This support is enabled by the use of multimode cables for FC-VI interconnects. FC-VI adapters operate at their highest speed by default. However, because of technical limitations with multimode cables, the default speed is often reduced to as low as 2 Gb per second. Thus, the performance of the FC-VI interconnect link is significantly reduced. Single-mode cable support addresses the performance drop by using a 16-Gbps FC-VI adapter.

On Brocade 6510 switches, Data ONTAP 8.2.1 supports encryption on the inter-switch link (ISL). In-flight encryption of data across the ISL minimizes the risk of unauthorized access, whether the data is moving within the data center or across long-distance links. The ISL uses switch-to-switch encryption, not data-at-rest or device encryption. Data is encrypted at the source and decrypted at the destination.

For MetroCluster support, the Cisco MDS 9710 multilayer director replaces the Brocade 300 series. For best-in-class availability, the multilayer director combines nondisruptive software upgrades, stateful process restart and failover, and full redundancy of all major components.

Starting with Data ONTAP 8.2.1, you can use unidirectional port mirroring, which increases performance throughput by more efficiently using the FC-VI links in a MetroCluster configuration.

To increase performance, MetroCluster supports aggregates that are composed of only solid-state disks.


Scalable SAN support was introduced in clustered Data ONTAP 8.1. Data ONTAP 8.1 supports up to 8 SAN data LIFs per Ethernet, HBA, or UTA port. Clustered Data ONTAP 8.2 supports up to 16 SAN data LIFs per port. Clustered Data ONTAP 8.2.1 supports up to 32 SAN data LIFS per port. With each release, scalability has increased.

Customers with workloads that include a significant amount of indirect data access or intracluster mirroring or a significant number of simultaneous volume moves might have a bandwidth problem. Their workloads might require more bandwidth across the cluster interconnect than the default two cluster ports can provide. Clustered Data ONTAP 8.2.1 increases the limit for FAS6280 and FAS6290 controllers to four cluster ports per node.

To increase caching capacity on entry-level platforms, clustered Data ONTAP 8.2.1 increases the sizes of the SSD caches for Flash Pool on FAS2220 and FAS2240 storage controllers. With earlier releases, the size limit per HA pair is 400 GB. With 8.2.1, the limit per pair is 800 GB.

Newly supported for the 8.2.1 release is a 2-port converged network adapter (CNA) that can be configured to support either 10-Gb Ethernet for FCoE or 16-Gb Fiber Channel. Performance is improved, and backward compatibility for 8-Gb Fiber Channel infrastructures is preserved.

iSCSI type-length-value (TLV) allows users to enable dedicated priority for iSCSI traffic using data center bridging(DCB) infrastructure. Priority assignment and bandwidth allocation is configured on a DCB capable switch. iSCSI TLV is currently only supported on the QLogic 8300 CNA controller.

Data ONTAP 8.2.1 introduces support for SAS optical cables on FAS3200 and FAS6200 platforms with SAS disk shelves using IOM6, and for clustered ONTAP 7-Mode stretch MetroCluster configurations.


This lesson focuses on the new Data ONTAP features that secure Data ONTAP solutions.


By default, LDAP communication between client and server applications is not encrypted. Therefore, userid and password information is not encrypted, which could compromise user credentials.

Clustered Data ONTAP 8.2.1 introduces Secure Sockets Layer (SSL) encryption between the cluster and Active Directory and OpenLDAP servers. NetApp used Transport Layer Security (TLS), an SSL-based protocol, to implement the LDAP over SSL feature.

Three new cluster shell command options were introduced to support the feature:

The -use-start-tls command is used when LDAP services are created or modified to enable an SVM to use SSL for name mapping.

The -use-start-tls-for-ad-ldap command is used when the CIFS security configuration of an SVM is created or modified to enable the SVM to use SSL for CIFS server creation and to enable LDAP queries to obtain information and IP addresses from a domain controller.

The -server-ca command is used to identify a new certificate type, a self-signed root certificate for server authentication.


Clustered Data ONTAP 8.2 introduced support for Active Directory authentication for cluster and SVM administrators. A dedicated, CIFS-licensed SVM serves as a communication tunnel to the administration server. With clustered Data ONTAP 8.2.1, the functionality is fully supported, but a CIFS protocol license is no longer required. This enhancement satisfies customers who want to use Active Directory to authenticate their storage and SVM administrators but do not need CIFS data access.


Active Directory domain structures are sometimes quite complex. To facilitate name mapping, Data ONTAP 8.2.1 supports name searches across multiple domains. To map the name of a UNIX user to the name of an active directory user, the SVM searches every bidirectional trusted domain. The SVM continues searching, from one trusted domain to another, until a match is found.

To specify the order in which the trusted domains are searched, you can configure a list of preferred trusted domains.
