  4. Metrocluster MetroCluster is a NetApp unique, cost-effective synchronous replication solution for combined HA and DR, protecting against site disasters within a campus or metropolitan area Configurations • Stretch MetroCluster Campus DR protection - Distances up to 500m • Fabric MetroCluster Metropolitan DR protection - Distances to 100 km

  5. MetroCluster Features & Benefits • Highest Level of Availability • Provides superior availability to RAID 1 + 0 • Protects against data center failures and site disasters for a negligible cost premium • Simple & Fast Recovery • Automatic Recovery for any single component failure • Single command recovery even for major catastrophic site failures • Cost-effective • Combines High Availability clustering with Disaster Recovery mirroring • Zero Data Loss • Synchronous data replication • Enhanced Read Performance • Up to 80% improved read performance for random reads, due to simultaneous read operations occurring on both plexes

  6. MetroCluster Components • Cluster license Provides automatic failover capability between sites in case of most hardware failures • SyncMirror Provides an up-to-date copy of data at the remote site; data is ready for access after failover without administrator intervention • ClusterRemote Provides a mechanism for administrator to declare site disaster and initiate a site failover via a single command for ease of use • FC Interconnect Provides filer connectivity between sites that are greater than 500 meters apart; enables sites to be located at a safe distance away from each other

  16. Highest Level of Availability with MetroCluster MetroCluster Storage Rack Failure(Controller, Disk Shelves) Data Center/Site Disaster Availability SyncMirror Shelf Failure (Backplane, Ops Panel) Triple Disk Failure Dual Shelf Failures (Controllers, PSU/Fans, Cables) FC Loop Failure (misbehaving disk) CFO + RAID-DP Storage Processor Failure Single Path Failure Single Shelf Module Failure Single HBA/Port Failure Double Disk Failure Single Disk Failure + MEDR

  17. Summary MetroCluster is a Netapp unique, cost-effective synchronous replication solution • For combined high availability and disaster recovery within a campus or metro area, that minimizes downtime with no data loss • For multiple sites within a campus or metro environment, that need a highly resilient storage-cluster solution for business-critical applications
