The number of disks that can be registered with one class is limited to a maximum of 1024.

There are the following limits to the number of disks that can be connected to one group:

To a mirror group, a maximum of 8 disks and lower level groups can be connected collectively. In other words, a maximum of eight-way multiplex mirroring is supported. However, be aware that the spare disk that will be automatically connected when a disk failure occurs is also included in the count.
To a stripe group, a maximum of 64 disks and lower level groups can be connected collectively. In other words, a maximum of 64-column striping is supported.
To a concatenation group, a maximum of 64 disks can be connected. In other words, a maximum of 64 disks can be concatenated.
To a switch group, a maximum of 2 disks can be connected.
