To preserve the existing data during the upgrade from FAS2520s to a new 2-node FAS8300 cluster, there are two important capabilities available to the storage administrator: the ability to move the volumes from the old nodes to the new nodes and the ability to pull out the tray of internal disks from the FAS2520s and reseat the tray in the internal storage of the FAS8300s. These actions ensure that the data is transferred and made accessible in the new system configuration.
The NetApp Interoperability Matrix Tool (IMT) is specifically designed to verify compatibility and supportability of different NetApp configurations including hardware models, software versions, and network components. It ensures that the specific models and configurations you plan to use will work together correctly, which is exactly what is needed when checking cluster interconnect switches for a configuration involving a FAS2720 HA pair and a FAS8300 HA pair.
When installing a new ONTAP 9.7 4-node cluster, the cluster interconnect network is required. This network type is essential for nodes within the cluster to communicate with each other, ensuring proper cluster management and operations.
ONTAP 9.7 All SAN Array (ASA) controllers operate with a symmetric active-active topology and support only SAN (block protocols) like FC and iSCSI. As of ONTAP 9.7, these controllers can only be configured as a standalone High Availability (HA) pair. This limitation ensures that the All SAN Array configuration is optimized for SAN workloads without the complexities and potential conflicts of integrating with NAS workloads or larger, mixed-use clusters.
In the given scenario, where the same range of client IP addresses is used on two separate networks that must not communicate with each other, the ONTAP feature that needs to be configured is IPspaces. IPspaces allow the segregation of network traffic and support overlapping IP address ranges on different physical or logical networks. This ensures that clients on one network cannot communicate with clients on the other, thereby providing the required security and access control.
