Infortrend SAS storage and Mac Pro Server

Hi
I have a new infortrend A12S-G2130 unit which I am trying to connect to a new Mac Pro Server unit via SAS.
The Mac Pro has snow leopard server with an LSI 9200-8e SAS card. The infortrend has 12 x 2TB drives which has been setup as a RAID 5 config which I did via the control panel on the actual infortrend unit.
The RAID has setup fine as all drive lights are green but when plugged into Mac it won't mount or even recognise that there is a SAS device attached. Can you suggest why or even what drivers I may need to install on the Mac so the LSI card will recognise that a SAS device is attached.

THanks.

This is a 2 step process
1) Configure the Infortrend to present LUNs / IDs to the host.  Just because you set up RAID levels doesn't mean that they will be seen by any particular controller arbitrarily.  
2) Make sure that the LSI9200 is configured in non-RAID mode, so all devices are passed-through.

Just because you have green lights doesn't mean that the RAID is correct.  it just means that no disks have failed.

Ok, thanks.

How do I configure the LSI card for non- RAID mode though? I just called LSI support and they are saying that particular card is not support for Mac OSX!
Also I'm assuming I configure the infortrend to present the LUNS to the host via the control panel on the unit?Sorry for the silly questions, I've not configured an infortrend unit for mac before!

Well, let's face it ... this is a moot point because you don't have a compatible controller card.
You can configure the infortrend via the RS232 port or their Java-based program (which means you need windows or linux) if you want a GUI.  The RS-232 configurator is menu-driven.

Ok, I think the easiest thing for me too do is run out and try to get an ATTO card from somewhere....at least I know their SAS cards support OSX! I just need to find somewhere in central London that stocks something like this!
Thanks for your advice though.

DavidPresidentCommented:
Good idea, the Atto cards are certainly supported.   You can also use them under windows to set up the infortrend via Java. Then just move the system over to your mac once it is set up.  You didn't mention the model of infortrend, but if it is the 6Gbit SAS-2, make sure you get a SAS-2 atto card. Otherwise you will saturate your SAS1 connection and not get all that you can out of the infortrend.

P.S. It has been a while, but i remember some store albyen or something like that a few blocks south of the british museum.  I remember they had atto.  I know they have more than one store in London as well.  Hope that helps.

HI
Yeah ATTO is the way forward. Tried Albion but they don't actually stock the cards only order and I wanted it today ideally so need to keep calling around but options are running out!

They are not apple stores, just a large retailer that focuses on Apple. I remember atto just because I'm in the storage 'biz and was surprised to see somebody carrying Atto fibre channel adapter cards, so it caught my eye.

DavidPresidentCommented:
That's it Albion.  You might also try any high-end video production company that uses Macs, or somebody that sells RAID for Apple.  We both know there are businesses that have these cards to sell in London, just a matter of finding them.  Atto web site may be of help.

Well i'll keep trying but running out of time! I might just have to wait until Monday and give my supplier some serious verbal abuse down the phone and get them to send me a card that actually works!!
Thanks for all your help though, it's just really frustrating!

I know that Apple OEMed the LSI fibre channel controllers for at least a while, and Apple was sole source of the drivers.  You may have to mentally prepare yourself that the supplier doesn't sell atto, who may be the only game in town to begin with for SAS-attach.
 I looked at the Atto site because I was curious, they list other OEM/resellers that may be able  to stick a card on a train for you so you can get it in a few hours.  Albion is not your only local option.

Hi
Just to let you know, my supplier is biking over an ATTO SAS H680 now for me to swap out so all should be sorted but thanks for your help.

LSI SAS cards are not compatible with Mac operating systems, stick to ATTO!
