What should the technical specialist explain when describing the addition of grid elements to an IBM FlashSystem A9000R?
A. Up to 12 MicroLatency modules can be attached to a grid element.
B. Six elements must be grown to nine elements initially.
C. Element interface options must be the same type.
D. MicroLatency module size can be intermixed.
Correct Answer: C
Explanation/Reference:
Grid elements installed must all be the same type (interface options and MicroLatency module size). An intermix of interface options or MicroLatency module capacities is not supported.
Note: Two grid controllers and one flash enclosure are combined to make one grid element.
Capacity, caching, and processing power are added at the same time by adding in one or more grid elements to scale up.
IBM Flash System A9000R consists of 2 – 6 grid elements, where a partially populated rack (2 – 5 grid elements) is expanded by adding grid elements to the maximum number of six-grid elements.
Incorrect Answers:
A: Each flash enclosure includes 12 flash modules (MicroLatency modules), battery modules, power supplies, and two fully redundant canisters, B: IBM Flash System A9000R consists of 2 – 6 grid elements.
D: The capacity of all MicroLatency modules across all grid elements in IBM FlashSystem A9000R must be the same.
