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

134 For other devices, it's possible that you'll have to write the

194 There are a number of logging types and you can find them in the

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

923 to addresses up to 1TB. When set to 2, the driver supports the
924 full 64-bit DMA address range, but can only address 16 segments
925 of 4 GB each. This limits the total addressable range to 64 GB.
926
927 Most machines with less than 4GB of memory should use a setting
928 of 0 for best performance. If your machine has 4GB of memory
929 or more, you should set this option to 1 (the default).
930
931 The still experimental value 2 (64 bit DMA addressing with 16
932 x 4GB segments limitation) can be used on systems that require
933 PCI address bits past bit 39 to be set for the addressing of
934 memory using PCI DAC cycles.

a7f7f624 1011 help
1da177e4
LT
1012 "Tagged command queuing" is a feature of SCSI-2 which improves
1013 performance: the host adapter can send several SCSI commands to a
1014 device's queue even if previous commands haven't finished yet.
1015 Because the device is intelligent, it can optimize its operations
1016 (like head positioning) based on its own request queue. Some SCSI
1017 devices don't implement this properly; if you want to disable this
1018 feature, enter 0 or 1 here (it doesn't matter which).
1019
1020 The default value is 8 and should be supported by most hard disks.
1021 This value can be overridden from the boot command line using the
1022 'tags' option as follows (example):
1023 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1024 4, set queue depth to 16 for target 2 and target 3 on controller 0
1025 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1026
1027 The normal answer therefore is to go with the default 8 and to use
1028 a boot command line option for devices that need to use a different
1029 command queue depth.
1030
1031 There is no safe option other than using good SCSI devices.

1041 Modern hard disks are able to support 64 tags and even more, but
1042 do not seem to be faster when more than 32 tags are being used.
1043
1044 So, the normal answer here is to go with the default value 32 unless
1045 you are using very large hard disks with large cache (>= 1 MB) that
1046 are able to take advantage of more than 32 tagged commands.
1047

1055 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1056 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1057 are respectively the maximum data transfer rates in mega-transfers
1058 per second for each class. For example, a FAST-20 Wide 16 device is
1059 able to transfer data at 20 million 16 bit packets per second for a
1060 total rate of 40 MB/s.
1061
1062 You may specify 0 if you want to only use asynchronous data
1063 transfers. This is the safest and slowest option. Otherwise, specify
1064 a value between 5 and 80, depending on the capability of your SCSI
1065 controller. The higher the number, the faster the data transfer.
1066 Note that 80 should normally be ok since the driver decreases the
1067 value automatically according to the controller's capabilities.
1068
1069 Your answer to this question is ignored for controllers with NVRAM,
1070 since the driver will get this information from the user set-up. It
1071 also can be overridden using a boot setup option, as follows
1072 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1073 for FAST-20 synchronous data transfer (20 mega-transfers per
1074 second).
1075
1076 The normal answer therefore is not to go with the default but to
1077 select the maximum value 80 allowing the driver to use the maximum
1078 value supported by each controller. If this causes problems with
1079 your SCSI devices, you should come back and decrease the value.
1080
1081 There is no safe option other than using good cabling, right
1082 terminations and SCSI conformant devices.

1368 Falcon, ...) say Y to get it supported. Of course also, if you have
1369 a compatible SCSI controller (e.g. for Medusa).

1375 This driver supports both styles of NCR integration into the
1376 system: the TT style (separate DMA), and the Falcon style (via
1377 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1378 in the Hades (without DMA).
