Which two NetApp features provide synchronous data replication between two sites for SAN workloads with automatic failover in case of a site disaster? (Choose two.)
For synchronous data replication between two sites with automatic failover in case of a site disaster for SAN workloads, the two NetApp features that provide these capabilities are SnapMirror Synchronous and MetroCluster IP.
SnapMirror Synchronous: This feature provides volume-granular, synchronous replication with zero RPO (Recovery Point Objective), ensuring that data is mirrored in real-time to a secondary site. This setup supports automatic failover, maintaining data availability even during site failures
MetroCluster IP: This solution provides synchronous replication and combines high availability and disaster recovery capabilities. MetroCluster IP uses IP networking to extend the distance over which replication can occur and supports automatic failover and failback, making it suitable for critical SAN workloads
An administrator runs the vserver nvme namespace convert-from-iun command on a NetApp ASA cluster to increase host performance.
What is modified by the convert command?
The vserver nvme namespace convert-from-lun command in a NetApp ASA cluster is used to convert a LUN to an NVMe namespace to increase host performance. This process involves modifying the metadata of the storage object to make it compatible with the NVMe protocol, allowing for faster access and reduced latency
Which NetApp feature presents LUNs only within the HA pair?
Selective LUN Mapping (SLM) is the feature that presents LUNs only within the HA pair. SLM allows administrators to control which LUNs are visible to which hosts, ensuring that LUNs are only accessible through the designated HA pair, thus improving security and manageability.
For more information, see:
NetApp Documentation on Selective LUN Mapping
NetApp Community on LUN Mapping
A customer requires multiple SAN and NAS protocols on a NetApp AFF cluster. The cluster must concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export.
Based on these requirements, what is the minimum data SVM count that is required?
To concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export, only one data SVM (Storage Virtual Machine) is required. NetApp ONTAP allows a single SVM to support multiple SAN and NAS protocols simultaneously, enabling efficient and consolidated management of storage resources.
For more information, refer to:
NetApp Documentation on SVM Configuration
NetApp SVM Best Practices
What is the maximum size for a LUN in NetApp ONTAP 9.14.1 software?
In NetApp ONTAP 9.14.1 software, the maximum size for a LUN is 128TiB. This limit ensures that large datasets can be stored and managed efficiently within a single LUN, catering to the needs of high-capacity SAN environments
