 The two throughput elements that are controlled by host applications are operation size and concurrency. Operation size refers to the amount of data that is transferred in a single I/O request, and concurrency refers to the number of I/O requests that are issued simultaneously. Both of these factors affect the throughput of a host application, as they determine how much data can be sent or received within a given time period. Larger operation sizes and higher concurrency can increase the throughput, but they may also increase the latency and resource consumption12. References: 1: NetApp Performance Analysis on Data ONTAP - Chapter 3: Host-Side Performance 2: NetApp Performance Analysis on Data ONTAP - Chapter 4: Storage System Performance

Data. However, I cannot guarantee the accuracy or completeness of this answer, and you should verify it with the NetApp Support Engineer ONTAP Specialist documents and learning resources.

A MetroCluster configuration requires the ISLs between the sites to be up and running for the switchover to occur. If the ISLs are down, the MetroCluster configuration cannot communicate with the other site and cannot perform the switchover. Additionally, a MetroCluster configuration requires all aggregates to be mirrored across the sites for data protection and availability. If a site has unmirrored aggregates, the switchover will fail because the data on those aggregates will not be accessible from the other site. References = Configuring the MetroCluster software in ONTAP, NetApp MetroCluster FC for ONTAP 9.8

To access a LUN on a FAS 8300 system from a VMware ESXi server through the FC protocol, the customer must configure the FC service on the SVM that owns the LUN. The FC service enables the SVM to act as an FC target and communicate with the FC initiators on the host. Without the FC service, the LUN will not be visible to the host, even if the LUN is mapped to an igroup and the FC LIFs are up. The exhibit shows that the FC service is not configured on the SVM, as theoutput of the command vserver fcp initiator show -vserver SVM1 is empty. Therefore, the reason for the problem is that the FC service has not been configured on the SVM. References = Configure an SVM for FC, Create an FC protocol service, Single IQN iSCSI session with ESXi on ONTAP when igroup has two IQNs
