A storage administrator has an existing FAS2554 HA pair. They want to add a new FAS2620 HA pair to the cluster. The SAN protocols are licensed.
Referring to the exhibit, after adding the second HA pair, how many more nodes are available to add for future use?
When adding the FAS2620 HA pair to the existing FAS2554 HA pair, the cluster's node limit will be governed by the platform supporting the fewest nodes, as stated in the footnotes. The FAS2554 has a maximum configuration of 8 nodes in a SAN environment. With 2 nodes from the existing FAS2554 HA pair and 2 nodes from the new FAS2620 HA pair, a total of 4 nodes will be used. This leaves room for 4 more nodes to reach the FAS2554's maximum limit of 8 nodes.
When a write from a SAN host is received, the information is stored within the controller before it is written to the underlying RAID.
In this scenario, which component stores the data?
In a SAN environment, when a write operation is received by the SAN host, the data is initially stored in Non-Volatile Random Access Memory (NVRAM) within the controller. NVRAM is used because it can securely store data even if there is a power loss, ensuring data integrity before it is written to the underlying RAID. This mechanism provides a high level of fault tolerance and reliability, which is critical in storage systems.
An administrator notices that the applications are running slowly. The administrator wants to determine which component on the ONTAP subsystem is experiencing the most latency.
In this scenario, which command would you use to accomplish this task?
To determine which component on the ONTAP subsystem is experiencing the most latency, the command 'qos statistics latency show' is used. This command provides detailed latency statistics for quality of service (QoS) on ONTAP, allowing the administrator to pinpoint the exact source of latency issues in the system. Other commands listed do not focus specifically on latency or may provide broader system statistics not directly relevant to identifying latency issues.
A customer has four or more nodes in a cluster. More than four target ports are being used by the SVMs in any node. The customer wants to limit the number of paths that can be used to access LUNs on the nodes, so that the paths do not exceed the recommended maximum of eight.
In this scenario, which three actions will accomplish this task? (Choose three.)
To limit the number of paths that can be used to access LUNs on the nodes and ensure they do not exceed the recommended maximum of eight, you can take the following actions: Use port sets for iSCSI, which will help in managing and reducing the number of paths by grouping certain ports together; Use Selective LUN Mapping to reduce the number of paths, as this allows you to control which LUNs are visible through which target ports; Use FC switch zoning to restrict the number of paths to LUNs by creating specific zones that limit the access paths. Together, these actions efficiently manage and control the number of paths, ensuring compliance with the recommended maximum.
A customer configured CIFS in an ONTAP 9.5 SVM. The customer wants to verify if the "CIFS Server" is accessible from each node of the cluster.
In this scenario, which command will accomplish this task?
To verify if the CIFS server is accessible from each node of the cluster in an ONTAP 9.5 SVM, you should use the 'vserver cifs check' command. This command checks the CIFS server's status and ensures it is operational across the entire cluster.
