22 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
23 any other SCSI device under Linux, say Y and make sure that you know
24 the name of your SCSI host adapter (the card inside your computer
25 that "speaks" the SCSI protocol, also called SCSI controller),
26 because you will be asked for it.

28 You also need to say Y here if you have a device which speaks
29 the SCSI protocol. Examples of this include the parallel port
30 version of the IOMEGA ZIP drive, USB storage devices, Fibre

697 This is a feature of SCSI-2 which improves performance: the host

706 This option enables elevator sorting for all probed SCSI disks and

708 random seeks, but this does not necessarily result in a noticeable

717 This specifies how many SCSI commands can be maximally queued for

719 only if you have disks with buggy or limited tagged command support.
720 Minimum is 2 and maximum is 62. This value is also the window size

722 by the driver for each probed SCSI device is reported at boot time.

1167 default "8"
1168 ---help---
1169 "Tagged command queuing" is a feature of SCSI-2 which improves
1170 performance: the host adapter can send several SCSI commands to a
1171 device's queue even if previous commands haven't finished yet.
1172 Because the device is intelligent, it can optimize its operations
1173 (like head positioning) based on its own request queue. Some SCSI
1174 devices don't implement this properly; if you want to disable this
1175 feature, enter 0 or 1 here (it doesn't matter which).
1176
1177 The default value is 8 and should be supported by most hard disks.
1178 This value can be overridden from the boot command line using the
1179 'tags' option as follows (example):
1180 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1181 4, set queue depth to 16 for target 2 and target 3 on controller 0
1182 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1183
1184 The normal answer therefore is to go with the default 8 and to use
1185 a boot command line option for devices that need to use a different
1186 command queue depth.
1187
1188 There is no safe option other than using good SCSI devices.

1198 Modern hard disks are able to support 64 tags and even more, but
1199 do not seem to be faster when more than 32 tags are being used.
1200
1201 So, the normal answer here is to go with the default value 32 unless
1202 you are using very large hard disks with large cache (>= 1 MB) that
1203 are able to take advantage of more than 32 tagged commands.
1204

1211 ---help---
1212 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1213 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1214 are respectively the maximum data transfer rates in mega-transfers
1215 per second for each class. For example, a FAST-20 Wide 16 device is
1216 able to transfer data at 20 million 16 bit packets per second for a
1217 total rate of 40 MB/s.
1218
1219 You may specify 0 if you want to only use asynchronous data
1220 transfers. This is the safest and slowest option. Otherwise, specify
1221 a value between 5 and 80, depending on the capability of your SCSI
1222 controller. The higher the number, the faster the data transfer.
1223 Note that 80 should normally be ok since the driver decreases the
1224 value automatically according to the controller's capabilities.
1225
1226 Your answer to this question is ignored for controllers with NVRAM,
1227 since the driver will get this information from the user set-up. It
1228 also can be overridden using a boot setup option, as follows
1229 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1230 for FAST-20 synchronous data transfer (20 mega-transfers per
1231 second).
1232
1233 The normal answer therefore is not to go with the default but to
1234 select the maximum value 80 allowing the driver to use the maximum
1235 value supported by each controller. If this causes problems with
1236 your SCSI devices, you should come back and decrease the value.
1237
1238 There is no safe option other than using good cabling, right
1239 terminations and SCSI conformant devices.
