This option allows you to specify the maximum number of scatter-
|
|
|
- gather entries per I/O. The driver defaults to 40, a reasonable number
|
|
|
- for most systems. However, the user may increase this up to 128.
|
|
|
- Increasing this parameter will require significantly more memory
|
|
|
- on a per controller instance. Increasing the parameter is not
|
|
|
- necessary (or recommended) unless the user will be running
|
|
|
- large I/O's via the raw interface.

|
+ gather entries per I/O. The driver default is 128, which matches
|
|
|
+ SCSI_MAX_PHYS_SEGMENTS. However, it may decreased down to 16.
|
|
|
+ Decreasing this parameter will reduce memory requirements
