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.

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.

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.

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.
