New and updated commands for performance data
Enhancements for Storage QoS- Data ONTAP now supports cache monitoring and autovolume workloads, and it provides an
improved system interface to define workloads and control them. Starting with Data ONTAP 8.3, the system automatically assigns an autovolume workload to each volume, and the volume statistics are available in the configuration data. New qos statistics volume commands enable you to monitor Storage QoS at the volume level instead of the aggregate level.
Enhancements to continuous segment cleaning
MetroCluster enhancements Support for MetroCluster configurations
Networking and security protocol enhancements Default port roles no longer automatically defined – Prior to Data ONTAP 8.3, default roles were assigned to each network port during configuration of
the cluster. Port roles are now defined when configuring the LIF that is hosted on the port.
Support for multi-tenancy – Beginning with Data ONTAP 8.3, you can create IPspaces to enable a single storage system to support multiple tenants. That is, you can configure the system to be accessed by clients from more than one disconnected network, even if those clients are using the same IP address. An IPspace defines a distinct IP address space in which Storage Virtual Machines (SVMs) reside. Ports and IP addresses defined for an IPspace are applicable only within that IPspace. A distinct routing table is maintained for each SVM within an IPspace; therefore, no cross-SVM or cross-
IPspace traffic routing occurs. A default IPspace is created when the initial cluster is created. You create additional IPspaces when
you need SVMs to have their own storage, administration, and routing.
IPv6 support enhancements
New networking features – Beginning with Data ONTAP 8.3, new networking features have been added to simplify the configuration of IPspaces and to manage pools of IP addresses.
The network IPspace commands enable you to create and manage additional IPspaces on your cluster. Creating an IPspace is an initial step in creating the infrastructure required for setting up multi-tenancy.
The network broadcast-domain commands enable you to configure and manage ports in a broadcast domain. When you create a broadcast domain, a failover group is automatically created for the ports in the broadcast domain.
The network subnet commands enable you to allocate specific blocks, or pools, of IP addresses for your Data ONTAP network configuration. When creating LIFs, an address can be assigned from the subnet and a default route to a gateway is automatically added to the associated SVM.
Storage resource management enhancements Performance increase for random read operations
Root-data partitioning available for entry-level and AFF platforms
Support for Flash Pool SSD partitioning
Support for Storage Encryption on SSDs
New disk name format – Starting in Data ONTAP 8.3, disk names have a new format that is based on the physical location of the disk. The disk name no longer changes depending on the node from which it is accessed.

Increased maximum cache limits
Change to the default action taken when moving a volume cutover occurs
Support for caching policies on Flash Pool aggregates

Networking simplicity
Broadcast domains – You can create broadcast domains to provide a logical division of a computer network. Broadcast domains enable you to group network ports that belong to the same datalink layer. The ports in the group can then be used to create network interfaces for data traffic or management traffic.
Subnets – You can create a subnet to provide a logical subdivision of an IP network to pre-allocate the IP addresses. A subnet enables you to create network interfaces more easily by specifying a subnet instead of an IP address and network mask values for each new interface.
IPv6 support – You can use IPv6 address on your cluster for various operations such as configuring LIFs, cluster peering, configuring DNS, configuring NIS, and configuring Kerberos.
Enhanced Storage Virtual Machine (SVM) setup wizard
BranchCache configuration
LUN move
Authenticated cluster peering
Qtree exports
Service Processors
Version-flexible mirror relationship – You can create a mirror relationship that is independent of the Data ONTAP version running on the
source and destination clusters.
Snapshot policies – You can create Snapshot policies at the SVM level, which enables you to create Snapshot policies for
a specific SVM
