Question 94

Which of the following statements about SDS software-defined storage and traditional storage in terms of storage system software is wrong?

A.The traditional bottom-up storage design model, HDD->DISKGroup->RAID->Storage Pool->LUN

B.In traditional storage system design, LUN is the basic unit of storage management. Before the user creates the LUN, the Storage has been defined by the manufacturer or administrator, and it has always existed in the storage system. For the user's LUN, the user can define very limited things.

C.The storage software architecture of SDS starts from the application and manages the storage with the application as the unit. The application first needs to create its own storage strategy, that is, the application's storage requirements, and then add storage volumes (such as vDisk) to this storage strategy. The collection of all user storage entities (vDisks) in a policy, we call it Storage Pool.

D.The storage software architecture of SDS needs to be covered from top to bottom, APP-vDisks-Container Storage Pool-HDD.

Question 95

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 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.

B.rack and blade deployment mixing: by a frame E9000 H2289 a minimum of 3 units, up to 16 units

C.When mixed deployment rack and blade: E9000 chassis supplied to the public 8 10GE Interface, DB nodes are arranged in E9000 chassis.

D.When the blade configuration deployment: provide a central unified external box 8 10GE interfaces, in principle, DB nodes are configured in a box.
