You Are Planning a Single-Site Nimble Solution with ISCSI Connectivity

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 statements 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.
B) A maximum of two switches can be used in an IRF stack when connecting storage.
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.
