6 TB 485 TB
The following figure shows an example of the front and rear views of a fully
populated XIV system.
Note: The modem is no longer supported as part of the rack configuration for
Indonesia and Brazil. For more information, contact your IBM planning

Minimally populated rack
A minimally populated rack for models 281x-114 and 281x-214 contains three data
modules and three interface modules, for a total of six modules. A minimally
populated rack for model 281x-314 contains three data modules and six interface
modules, for a total of nine modules.
Each module contains twelve 1 TB limited capacity, 2 TB , 3 TB, or 4 TB, 3 TB, 4
TB, or 6 TB disk drive modules (DDMs), for a total of 72 DDMs (6 modules x 12
DDMs) for models 281x-114 and 281x-214 and 108 DDMs (9 modules x 12 DDMs)
for model 281x-314.
