Report
Export

You are planning a single-site Nimble solution with iSCSI connectivity. Two 10GbE SFP+ dual port NICs are included in the configuration. You designed an Intelligent Resilient Framework (IRF) stack with HPE FlexFabric 5900CP switches.

Which statement is correct when discussing the IRF limits for this configuration?

A.
When connecting an iSCSI storage to an IRF stack, a minimum of four 10GbE ports must be used per switch.

Answers
C.
In an IRF stack with storage connectivity, the 40GbE ports cannot be used.
D.
The used IRF ports for iSCSI traffic have to be configured as 10GbE converged ports.
Answers
D.
The used IRF ports for iSCSI traffic have to be configured as 10GbE converged ports.
Suggested answer: B

Explanation:

When designing an Intelligent Resilient Framework (IRF) stack for a Nimble storage solution using HPE FlexFabric 5900CP switches with iSCSI connectivity, the IRF stack typically supports up to two switches for optimal performance and redundancy. This limitation ensures that the iSCSI traffic is managed effectively without overcomplicating the network topology, which could potentially introduce latency or complexity in managing the stack.

Utilizing more than two switches in an IRF stack when connecting to storage could result in diminished returns in performance or increased management overhead, which is why HPE typically recommends limiting the IRF stack to two switches in such configurations.
