21 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
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),
25 because you will be asked for it.
26
27 You also need to say Y here if you have a device which speaks
28 the SCSI protocol. Examples of this include the parallel port
29 version of the IOMEGA ZIP drive, USB storage devices, Fibre

375 This driver supports HP Smart Array Controllers (circa 2009).
376 It is a SCSI alternative to the cciss driver, which is a block
377 driver. Anyone wishing to use HP Smart Array controllers who
378 would prefer the devices be presented to linux as SCSI devices,
379 rather than as generic block devices should say Y here.

1136 ---help---
1137 "Tagged command queuing" is a feature of SCSI-2 which improves
1138 performance: the host adapter can send several SCSI commands to a
1139 device's queue even if previous commands haven't finished yet.
1140 Because the device is intelligent, it can optimize its operations
1141 (like head positioning) based on its own request queue. Some SCSI
1142 devices don't implement this properly; if you want to disable this
1143 feature, enter 0 or 1 here (it doesn't matter which).
1144
1145 The default value is 8 and should be supported by most hard disks.
1146 This value can be overridden from the boot command line using the
1147 'tags' option as follows (example):
1148 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1149 4, set queue depth to 16 for target 2 and target 3 on controller 0
1150 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1151
1152 The normal answer therefore is to go with the default 8 and to use
1153 a boot command line option for devices that need to use a different
1154 command queue depth.
1155
1156 There is no safe option other than using good SCSI devices.

1162 ---help---
1163 This option allows you to specify the maximum number of commands
1164 that can be queued to any device, when tagged command queuing is
1165 possible. The default value is 32. Minimum is 2, maximum is 64.
1166 Modern hard disks are able to support 64 tags and even more, but
1167 do not seem to be faster when more than 32 tags are being used.
1168
1169 So, the normal answer here is to go with the default value 32 unless
1170 you are using very large hard disks with large cache (>= 1 MB) that
1171 are able to take advantage of more than 32 tagged commands.
1172
1173 There is no safe option and the default answer is recommended.

1179 ---help---
1180 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1181 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1182 are respectively the maximum data transfer rates in mega-transfers
1183 per second for each class. For example, a FAST-20 Wide 16 device is
1184 able to transfer data at 20 million 16 bit packets per second for a
1185 total rate of 40 MB/s.
1186
1187 You may specify 0 if you want to only use asynchronous data
1188 transfers. This is the safest and slowest option. Otherwise, specify
1189 a value between 5 and 80, depending on the capability of your SCSI
1190 controller. The higher the number, the faster the data transfer.
1191 Note that 80 should normally be ok since the driver decreases the
1192 value automatically according to the controller's capabilities.
1193
1194 Your answer to this question is ignored for controllers with NVRAM,
1195 since the driver will get this information from the user set-up. It
1196 also can be overridden using a boot setup option, as follows
1197 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1198 for FAST-20 synchronous data transfer (20 mega-transfers per
1199 second).
1200
1201 The normal answer therefore is not to go with the default but to
1202 select the maximum value 80 allowing the driver to use the maximum
1203 value supported by each controller. If this causes problems with
1204 your SCSI devices, you should come back and decrease the value.
1205
1206 There is no safe option other than using good cabling, right
1207 terminations and SCSI conformant devices.
