= Vendor information =

3Ware (http://www.3ware.com) card are usually well supported on Linux.[[BR]]
Theses cards are often considered as some of the bests hardware RAID controllers for GNU/Linux or BSD systems.[[BR]]
3Ware supports Linux and provide an '''opensource kernel driver''' which is part of Linux since ages.

[[BR]]
= Linux kernel drivers =

There is two drivers for 3ware cards:
|| Driver || Supported cards ||
|| 3w_xxxx || 3Ware Eskalad 7000 and 8000 series ||
|| 3w_9xxx || 3Ware Eskaled 9000 series ||

You should not expect any problems with theses drivers which are known to be '''mature''' and '''stable'''.[[BR]]
We don't know any current Linux distrubtion which miss theses drivers so no additional step should be required to get it working.

[[BR]]
= Management and reporting tools =

It currently exists '''no opensource tools''' for the 3Ware cards.
However, 3Ware provides two proprietary utilities for x86 and x86_64 linux systems.

== tw_cli ==

tw_cli is a command line tool to manage and monitore Eskaled cards. It works fine with 7000 and 8000 cards, as well as with the 9000 series.[[BR]]
Latest version is 2.00.07.009, available in 3Ware applications package release 9.5.0.1.

=== My opinion about tw_cli ===

tw_cli is really a good utility. It show all needed informations in just one command (info c0).[[BR]]
Moreover, it show rebuild status in percent when the array is rebuilding and it's easily parsable because 3Ware filled the not relevant columns with a dash instead of let them empty. Good job !


== 3ware-status ==

3ware-status is a package I wrote by myself. It includes a python wrapper around tw_cli command and an initscript which daemonize the launch of the wrapper.[[BR]]
It also handle failure detection and report it by mail and syslog. It also handle unexpected output change and reminder until the status is fine again.

''GRAB-IT NOW FROM OUR REPOSITORY''

Example output:
{{{

-- Arrays informations --

c0u0p1  VNRD3EC4C7HZZM  OK
}}}

== 3dm2 ==

3DM2 is a Web applications with an embedded web servers that allow use to do the same things than with tw_cli but graphical.[[BR]]
It's works fine and doesn't rely on insane dependencies like java, tomcat or something else.
