Rack configuration features
You can order an XIV system with a total of six or nine to 15 modules.
Seven-module and eight-module configurations are not supported.
Note: For model 281x-314, a minimum total of nine modules are required, three
data and six interface. For more information, see Rack components.
Table 5 shows the various system configuration options with their feature codes.
Note: The six module feature does not apply to model 281x-314.

The IBM XIV Storage System requires a corresponding software license for each
entitled data or interface module.
Partially populated configurations have the same power, floor planning, hardware,
software, and cabling configurations as fully populated systems. In other words,
partially populated racks are identical to fully populated rack, except that they
have fewer modules and therefore less storage capacity.
Note: XIV systems with less than 13 modules also have fewer usable Fibre
Channel and iSCSI ports. For more information, see Table 11 on page 17.
Fully populated rack (15 modules)
A fully populated rack contains nine data modules and six interface modules, for a
total of 15 modules.
Each module contains 12 1 TB limited capacity, 2 TB, 3 TB, 4 TB, or 6 TB disk drive
modules (DDMs), for a total of 180 DDMs in a fully populated rack (15 modules x
12 DDMs).
Note: Only the 4 TB and 6 TB DDM options are available for model 281x-314.
Table 6 shows the various configuration limits for a fully populated rack's data
storage.
