D . Systems purchased with eight 1.2 TB flash modules can be expanded to twelve 2.9 TB flash modules.
Answer: C
Explanation:
FlashSystem 900 can be populated with up to 12 x 1.2 TB IBM MicroLatency modules in increments of 4,
6, 8, 10, or 12; or up to 12 x 2.9 TB or 5.7 TB IBM MicroLatency modules in increments of 6, 8, 10, or 12.
These modules of either 1.2 TB, 2.9 TB, or 5.7 TB cannot be intermixed. Capacity can be upgraded by
purchasing the AF23 (1.2 TB), AF24 (2.9 TB)) or AF25 (5.7 TB) IBM MicroLatency module feature codes
as MES upgrades. Here are the upgrade paths:
