Question ESB2 chip + Linux, compatibilty? (5000x mobo)


I'm looking into buying a new system and the new line of Intel dual cores has caught my eye. I'm particularly interested in the Xeon 51xx serie, which is the server/workstation line.
Crucial is finding the right mobo: chipsets 5000p & 5000v are for servers and 5000x is for workstations but my question pertains all.

Part of the chipset is a "ESB2 SATAII Controller". From what I've been able to find is this chip used in RAID configurations although the word 'controller' suggests a more general function. The term 'ESB2' is also used in connection to Lan and PCI which confuses me.

Below are links to examples of mobo's with the 5000x chipset (but the chip can also be found on 5000p/v boards) from different manufacturers:
Code:
http://www.supermicro.com/products/motherboard/Xeon1333/5000X/X7DAE.cfm
http://www.tyan.com/products/html/tempesti5000xt_spec.html
http://www.iwill.net/product_2.asp?p_id=109
The Supermicro site also has a OS compatibility chart:
Code:
http://www.supermicro.com/support/resources/OS/5000XCompatibility.cfm
where none of the listed Linux distro's apparantly have "ESB2 (Intel Firmware) Support" (scroll down)

My questions:
- Can somebody explain what the ESB2 does/is for (in n00b speak )?
- I want to use Linux with this mobo, is this board suitable for me? (given the following requirements: )
- I don't want a RAID configuration (personally, others may want to, so feel free to expand),
- I do want to use the PCI capabilities to the max (some day),
- I do want to use the Ethernetnet capabilities to the max (all 2 of the ports),
- I do want to use the amount of harddiscs to the max (some day).

I must admit I haven't mailed a mobomaker with these questions and I'm not even close to ordering a system so I also haven't looked at shops which may have an answer. I did try something though, have a good laugh at this:

Dear Mr. Xxxxx,

Thank you for your email.

Please be aware that Intel does not offer in-depth presales support;
for specific advice and help, we would recommend that you contact one of
our authorised retailers. A list can be found at:
Which is nice to know if you're looking into spending a couple of 1000 euro's/dollars on their products

Right, I can answer my own question partly.
ESB2 = Enterprise SouthBridge. Makes sense once figured out.
It has a hardware RAID possibility but that's not supported with Linux.
Quote:
because the ESB2 Southbridge from Intel supports HARDWARE based RAID 0/1/5/10 across the 6 SATA ports. Not to mention that every 5000x based dual Xeon motherboard with the ESB2 Southbridge that I have found for sale does indeed support hardware RAID 0/1/5/10
Quote:
HostRAID function is not supported under Linux.
Quotes found on a Mac forum and a server vendor's site.
Whether this board holds other surprises for Linux users remains to be seen.
Edit: and it seems to me (--> n00b) you need to check out what your distro supports from the ESB2, depending on kernel version.

Linux & ESB2 problems

Did you find any other issues with Linux and that MB & ESB2 controller?

I am running into RH 5.2 and rPath not being able to see the SATA HD connected. I have gone into the BIOS, made sure the BIOS is up to date and that the controller (which has an Intel & an Adaptec RAID) is in a JBOD mode.

Any guidance is appreciated,
Thanks

Hello katchoo and welcome to (finally) posting on Linux Questions.

I can't answer your question since I bought a different mobo/chipset. What does JBOD mean in this respect, does that mean you're trying to access the HD as just a SATA disk (essentially not using the controller but for a minimum level)? That's where I'd start: trying to get the disk working as an ordinary SATA disk.

(side note: you revived a nearly 3 year old thread, well done )
