23 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
24 any other SCSI device under Linux, say Y and make sure that you know
25 the name of your SCSI host adapter (the card inside your computer
26 that "speaks" the SCSI protocol, also called SCSI controller),
27 because you will be asked for it.
28
29 You also need to say Y here if you have a device which speaks
30 the SCSI protocol. Examples of this include the parallel port
31 version of the IOMEGA ZIP drive, USB storage devices, Fibre

319 SCSI requests and responses over a TCP/IP network between the host
320 (the "initiator") and "targets". Architecturally, the iSCSI driver
321 combines with the host's TCP/IP stack, network drivers, and Network

1111 ---help---
1112 "Tagged command queuing" is a feature of SCSI-2 which improves
1113 performance: the host adapter can send several SCSI commands to a
1114 device's queue even if previous commands haven't finished yet.
1115 Because the device is intelligent, it can optimize its operations
1116 (like head positioning) based on its own request queue. Some SCSI
1117 devices don't implement this properly; if you want to disable this
1118 feature, enter 0 or 1 here (it doesn't matter which).
1119
1120 The default value is 8 and should be supported by most hard disks.
1121 This value can be overridden from the boot command line using the
1122 'tags' option as follows (example):
1123 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1124 4, set queue depth to 16 for target 2 and target 3 on controller 0
1125 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1126
1127 The normal answer therefore is to go with the default 8 and to use
1128 a boot command line option for devices that need to use a different
1129 command queue depth.
1130
1131 There is no safe option other than using good SCSI devices.

1141 Modern hard disks are able to support 64 tags and even more, but
1142 do not seem to be faster when more than 32 tags are being used.
1143
1144 So, the normal answer here is to go with the default value 32 unless
1145 you are using very large hard disks with large cache (>= 1 MB) that
1146 are able to take advantage of more than 32 tagged commands.
1147

1155 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1156 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1157 are respectively the maximum data transfer rates in mega-transfers
1158 per second for each class. For example, a FAST-20 Wide 16 device is
1159 able to transfer data at 20 million 16 bit packets per second for a
1160 total rate of 40 MB/s.
1161
1162 You may specify 0 if you want to only use asynchronous data
1163 transfers. This is the safest and slowest option. Otherwise, specify
1164 a value between 5 and 80, depending on the capability of your SCSI
1165 controller. The higher the number, the faster the data transfer.
1166 Note that 80 should normally be ok since the driver decreases the
1167 value automatically according to the controller's capabilities.
1168
1169 Your answer to this question is ignored for controllers with NVRAM,
1170 since the driver will get this information from the user set-up. It
1171 also can be overridden using a boot setup option, as follows
1172 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1173 for FAST-20 synchronous data transfer (20 mega-transfers per
1174 second).
1175
1176 The normal answer therefore is not to go with the default but to
1177 select the maximum value 80 allowing the driver to use the maximum
1178 value supported by each controller. If this causes problems with
1179 your SCSI devices, you should come back and decrease the value.
1180
