An organization wants to deploy cloud applications using block storage. The architect has included a hyper-scale storage solution in the cloud design.
Which requirements led to including this solution in the design?
A. Organization wants to purchase a storage array
Organization will use a full mesh topology to combine storage and application processing
B. Organization wants to purchase a storage array
Organization will use a spine/leaf topology to combine storage and application processing
C. Organization wants to purchase a storage array
Organization wants to keep storage processing separate from the application processing
D. Organization does not want to purchase a storage array
Organization wants to use a full mesh topology to combine storage and application processing
Correct Answer: B
Explanation/Reference:
When customers want converged/hyper-converged infrastructure appliances (or rack scale systems) – what customers ask for is this:
They want a management and orchestration stack that spans the domains of compute/storage/virtualization (in appliances), and this extends to the topof- rack network and spine/leaf network (in rack-scale systems that must scale to and beyond rack boundaries operationally).
Note: Hyperscale storage is the storage of vast quantities of information in media capable of increasing in size rapidly, efficiently, and indefinitely. In a data center, hyperscale storage capacity commonly runs into the petabytes.
