22 any other SCSI device under Linux, say Y and make sure that you know
23 the name of your SCSI host adapter (the card inside your computer
24 that "speaks" the SCSI protocol, also called SCSI controller),

28 the SCSI protocol. Examples of this include the parallel port

696 This is a feature of SCSI-2 which improves performance: the host
697 adapter can send several SCSI commands to a device's queue even if
698 previous commands haven't finished yet.

716 This specifies how many SCSI commands can be maximally queued for
717 each probed SCSI device. You should reduce the default value of 16
718 only if you have disks with buggy or limited tagged command support.
719 Minimum is 2 and maximum is 62. This value is also the window size
720 used by the elevator sorting option above. The effective value used
721 by the driver for each probed SCSI device is reported at boot time.

1160 default "8"
1161 ---help---
1162 "Tagged command queuing" is a feature of SCSI-2 which improves
1163 performance: the host adapter can send several SCSI commands to a
1164 device's queue even if previous commands haven't finished yet.
1165 Because the device is intelligent, it can optimize its operations
1166 (like head positioning) based on its own request queue. Some SCSI
1167 devices don't implement this properly; if you want to disable this
1168 feature, enter 0 or 1 here (it doesn't matter which).
1169
1170 The default value is 8 and should be supported by most hard disks.
1171 This value can be overridden from the boot command line using the
1172 'tags' option as follows (example):
1173 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1174 4, set queue depth to 16 for target 2 and target 3 on controller 0
1175 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1176
1177 The normal answer therefore is to go with the default 8 and to use
1178 a boot command line option for devices that need to use a different
1179 command queue depth.
1180
1181 There is no safe option other than using good SCSI devices.

1191 Modern hard disks are able to support 64 tags and even more, but
1192 do not seem to be faster when more than 32 tags are being used.
1193
1194 So, the normal answer here is to go with the default value 32 unless
1195 you are using very large hard disks with large cache (>= 1 MB) that
1196 are able to take advantage of more than 32 tagged commands.
1197

1204 ---help---
1205 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1206 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1207 are respectively the maximum data transfer rates in mega-transfers
1208 per second for each class. For example, a FAST-20 Wide 16 device is
1209 able to transfer data at 20 million 16 bit packets per second for a
1210 total rate of 40 MB/s.
1211
1212 You may specify 0 if you want to only use asynchronous data
1213 transfers. This is the safest and slowest option. Otherwise, specify
1214 a value between 5 and 80, depending on the capability of your SCSI
1215 controller. The higher the number, the faster the data transfer.
1216 Note that 80 should normally be ok since the driver decreases the
1217 value automatically according to the controller's capabilities.
1218
1219 Your answer to this question is ignored for controllers with NVRAM,
1220 since the driver will get this information from the user set-up. It
1221 also can be overridden using a boot setup option, as follows
1222 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1223 for FAST-20 synchronous data transfer (20 mega-transfers per
1224 second).
1225
1226 The normal answer therefore is not to go with the default but to
1227 select the maximum value 80 allowing the driver to use the maximum
1228 value supported by each controller. If this causes problems with
1229 your SCSI devices, you should come back and decrease the value.
1230
1231 There is no safe option other than using good cabling, right
1232 terminations and SCSI conformant devices.
