In a Nimble solution with iSCSI connectivity using an Intelligent Resilient Framework (IRF) stack with HPE FlexFabric 5900CP switches, there is a limitation on the number of switches that can be used in the IRF stack when connecting storage. Specifically, a maximum of two switches can be included in the IRF stack to ensure optimal performance and reliability when managing iSCSI traffic. This configuration ensures that the storage network maintains high availability and efficient data handling without overcomplicating the stack.

When performing capacity planning for HPE Nimble Storage using deduplication, it's important to understand that deduplication is applied at the pool level and operates on a block size basis. This means that all volumes within a pool benefit from deduplication, and the efficiency of the process depends on the block size and the type of data stored within the pool. Proper capacity planning requires taking into account the pool configuration, block size, and expected deduplication ratios to accurately predict storage savings and performance.

The issue of seeing multiple volumes after creating just a single volume on the MSA is likely due to a lack of zoning on the Fibre Channel switches. Zoning is a method used in Fibre Channel networks to segment a fabric into smaller, manageable zones, which helps in controlling access between devices. By enabling zoning on the SN3000B switches, the customer can isolate the connections and ensure that only the desired host can see specific volumes. This prevents the scenario where multiple volumes are visible to a host that should only have access to one.
