config FC4
tristate "Fibre Channel and FC4 SCSI support"
---help---
Fibre Channel is a high speed serial protocol mainly used to
connect large storage devices to the computer; it is compatible with
and intended to replace SCSI.
This is an experimental support for storage arrays connected to your
computer using optical fibre cables and the "X3.269-199X Fibre
Channel Protocol for SCSI" specification. If you want to use this,
you need to say Y here and to "SCSI support" as well as to the
drivers for the storage array itself and for the interface adapter
such as SOC or SOC+. This subsystem could even serve for IP
networking, with some code extensions.
If unsure, say N.
comment "FC4 drivers"

config FC4_SOC
tristate "Sun SOC/Sbus"
depends on FC4!=n && SPARC
help
Serial Optical Channel is an interface card with one or two Fibre
Optic ports, each of which can be connected to a disk array. Note
that if you have older firmware in the card, you'll need the
microcode from the Solaris driver to make it work.
To compile this support as a module, choose M here: the module will
be called soc.
config FC4_SOCAL
tristate "Sun SOC+ (aka SOCAL)"
depends on FC4!=n && SPARC
---help---
Serial Optical Channel Plus is an interface card with up to two
Fibre Optic ports. This card supports FC Arbitrated Loop (usually
A5000 or internal FC disks in E[3-6]000 machines through the
Interface Board). You'll probably need the microcode from the
Solaris driver to make it work.
To compile this support as a module, choose M here: the module will
be called socal.

config SCSI_PLUTO

help
This driver drives FC-AL disks connected through a Fibre Channel
card using the drivers/fc4 layer (currently only SOCAL). The most
common is either A5000 array or internal disks in E[3-6]000
machines.
To compile this support as a module, choose M here: the module will
be called fcal.

* Supported hardware:
* Tested on SOC sbus card bought with SS1000 in Linux running on SS5 and Ultra1.
* For SOC sbus cards, you have to make sure your FCode is 1.52 or later.
* If you have older FCode, you should try to upgrade or get SOC microcode from Sun
* (the microcode is present in Solaris soc driver as well). In that case you need
* to #define HAVE_SOC_UCODE and format the microcode into soc_asm.c. For the exact
* format mail me and I will tell you. I cannot offer you the actual microcode though,
* unless Sun confirms they don't mind.
