With the (default) setting "Controlling CM = Auto" ETERNUSmgr automatically assigns the RAID group to a
Control Module (CM) and a CPU in the CM. The assignment can also be made directly by specifying a CM# and
a CPU#.
As FC ports are also assigned to a CM and a CPU, direct assignment can also lead to better performance results
under certain circumstances.

Controller
DX/AF series
A maximum of 128 Volumes can be created per RAID Group
BS2000 supports a maximum of 2**32 - 1 blocks of 512 bytes per logical volume. Logical volumes of 2TB or
larger are thus not completely utilized by BS2000. Only use values of up to 2048 x 1024 = 2,097,152 in
"Capacity".
The recommended capacity of the logical volumes for BS2000 should be between 25 GB and 100 GB.
The maximum supported LUN capacity is 2TB.
