MetroCluster MetroCluster in clustered Data ONTAP 8.3

MetroCluster™ technology enables business continuity and continuous availability beyond the data center

Cluster A inData Center A

FAST LANE 2015 | 4

MetroCluster Two-Node MetroCluster

Distances of up to 200 km between sites

All storage is fabric-attached and visible to both nodes

Same level of protection of an HA-pair

Switchover and switchback transfer the cluster’s entire workload between sites

Support stretch MetroCluster (500 meters)

*Four-node MetroCluster highly recommended because of local HA failover support

FAST LANE 2015 | 5

MetroCluster Supported Two-Node MetroCluster Configurations

Foreign LUN Import Enhancements

Migration of third-party LUNs into Clustered Data ONTAP

No license fees

Automatic LUN alignment

No DTA 2800 (data migration appliance)

Online and offline modes

FAST LANE 2015 | 7

Foreign LUN Import Enhancements

Block based copy of course LUN contents

Copies to a pre-created flexible volume

TR-4380 SAN migration using foreign LUN import methodology

Minimal downtime for cutover

Other use cases

May be useful for LUNs with unaligned I/O

32-bit to 64-bit upgrades

FAST LANE 2015 | 8

SVM DR

Eliminate failover complexity

Simple predefined failover steps

Ease of management with automation

Protection for SVM data

Protects SVM identity and namespace, not just volumes

Automated setup and provisioning

Managed with SnapMirror commands

SnapMirror for SVM DR

FAST LANE 2015 | 9

SnapMirror for SVM (SVM DR) Overview Eliminate Failover Complexity & Enhance Ease of Management

Identity-Preserve mode Secondary SVM assume identity of primary Most configuration passes to secondary

CIFS clients reconnect seamlessly NFS clients must remount Network Settings may require reconfiguration

if switching subnets

Key Functional Attributes in 8.3.1

Single schedule for all data VOLs & Configuration

SnapMirror CMDs apply to SVM, not individual VOLs

SVM root VOL not replicated, namespace within it is replicated (Symlinks, ACL)

In ID, preserves true mode destination SVM offline in mirrored state with LIFs inactive

On a cluster reboot, a SVM DR source must be manually started

SAN configuration not replicated

Additional Enhancements to 8.3.1

Audit Log Forwarding

Cluster peering in non-default IPspaces

All flash FAS enhancements

FAST LANE 2015 | 19

All FAS Flash Enhancements

In-line compression enabled on all volumes

Up to a two-to-one space savings from compression

alone; additional savings from cloning and snapshots

Reduced latency for read workloads

All flash FAS clusters

FAST LANE 2015 | 20

Cluster Peering with Non-Default IPspace

Typical use case: backup and DR as a service

Peer from any user-created IPspaces

Use one inter-cluster LIF per node, per IPspace

Create discrete peering networks by tenant

FAST LANE 2015 | 21

Audit Log Forwarding

Enhanced security and compliance

Up to 10 remote syslog destinations
