NOTE: The following three options affect the amount of memory used by the
driver. For information on how memory is allocated by the driver, and to get
an approximate feel for the amount of memory which is saved by invoking
these parameters, refer to Memory Allocation under Important Additional In-
formation at the end of this section.
If the product of max_hbas * max_id * max_lun is small (less than 100), system
performance may suffer. These values determine the number of IO buffers allocated
by the driver. Allocation of too few may degrade performance.
Using the Maximum Host Adapters Option
Command line option: max_hbas=
Default value:
8
Valid options: 1-8
Function: Specify the maximum number of host adapters to support.
Possible Impact: If number is reduced, it may allow for reduction in the
memory used by the driver. Reduction may also result in performance degradation.
This parameter is used to optimize the use of dynamically allocated memory by the
driver. If your system has less than 8 Symbios Logic based PCI host adapters, in-
cluding any Symbios PCI-SCSI controllers designed into the mainboard, this pa-
rameter allows you to reduce the total memory used for the driver.
Using the Maximum SCSI IDs Option
Command line option: max_id=
Default value:
32
Valid options: 8-32
Function: Specify the maximum number of SCSI IDs each host adapter
board should support.
Possible Impact: If number is reduced, may allow for reduction in memory
used by the driver. Reduction may also result in performance
degradation.
This parameter is used to optimize the use of dynamically allocated memory by the
driver. If all the host adapters, including any SCSI controllers on the mainboard are
connected to less than 31 devices, you can reduce the size of the dynamically allo-
cated memory by setting this value to the maximum number of devices on any of the
SCSI controllers.
