The driver default is 128, which matches MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this can be 256. However, it may decreased down to 16. Decreasing this parameter will reduce memory requirements on a per controller instance. config SCSI_MPT3SAS_MAX_SGE int "LSI MPT Fusion SAS 3.0 Max number of SG Entries (16 - 256)" depends on PCI && SCSI && SCSI_MPT3SAS default "128" range 16 256 help This option allows you to specify the maximum number of scatter- gather entries per I/O.
