Cylinder/Head/Sector Mapping:
In the world of SCSI, drive capacity is decided by the number of
blocks. For some of the operating systems (Sun Solaris...etc.) the OS
will read the capacity based on the cylinder/head/sector count of
the drive. For Sun Solaris, the cylinder cannot exceed 65535, so user
can choose "cylinder<65535,” the controller will automatically adjust
the head/sector count, then the OS can read the correct drive
capacity. Please refer to “Advanced Features” in Appendix B and
also to the related documents provided with your operating system.
Cylinder, Head, Sector counts are selectable from the menu. To
avoid the difficulties with Sun Solaris configuration, the values
listed below can be applied.

< 64 GB ? 64 32
64 - 128 GB ? 64 64
128 – 256 GB ? 127 64

Older Solaris versions do not support drive capacity larger than 1
terabyte.
