Explanation

Two key requirements for a Cisco HyperFlex All Flash standard cluster are: (C) If the Jumbo MTU option is enabled in the HyperFlex installer, jumbo frames must also be configured on all upstream network switches - the installer enables jumbo frames on the HyperFlex nodes and vSwitches, but upstream switches (ToR/access layer) must be manually configured to support MTU 9000, otherwise storage traffic will be dropped. (E) All servers must be discovered by UCS Manager, in an unassociated state (no service profile assigned), and connected to both Fabric Interconnects before beginning the HyperFlex cluster deployment. The hypervisors do NOT need to be pre-installed on FlexFlash SD cards (B is wrong); the HyperFlex installer handles ESXi installation. HyperFlex All Flash clusters use only SSDs, not a mix of HDD and SSD (D is wrong).
