Regarding the first use of rack and blade networking in the hyper-converged database scenario, which of the following statement is correct? (Multiple choice)

• A.When the blade configuration deployment: provide a central unified external box 8 10GE interfaces, in principle, DB nodes are configured in a box.
• B.When mixed deployment rack and blade: E9000 chassis supplied to the public 8 10GE Interface, DB nodes are arranged in E9000 chassis.
• C.When the blades are deployed, they are assembled through the central frame. When there is no external switch, the maximum support does not exceed 4 frame cascading. If more than 4 frames, external IB switches need to be added.
• D.rack and blade deployment mixing: by a frame E9000 H2289 a minimum of 3 units, up to 16 units
