I have a couple of these LSI arrays

LSI Model 0834
LSI product name: 1932
LSI Product codename: Mary Jane
Enclosure name: Shea (DM1300)
End of Life: 31-Dec-2010

but I can't find any information about the FiberChannel interface is uses to the host. Right now it is connected for a BlueArc Mercury 50 filer, which also is have reached EOL.

Question

Can I buy any FC card, or What should I look for, when I want to connect this array to a Linux host?

I don't understand why you wouldn't contact your local LSI office/partner and ask them. –  Iain Jul 4 '14 at 9:26

They said they can't help me with products that have reached end of life =( –  Jasmine Lognnes Jul 4 '14 at 9:28

First off - check vendor recommendations. Some vendors are more scrupulous than others, but they'll generally have a list of 'known compatible' cards.

If you lack this information - as you seem to - I would start with buying Emulex or QLogic HBAs, and avoid anything else unless you have a specific entry in an interoperability matrix.

You will probably need to look as array specific card settings though - whilst they generally work by default, there's a noticeable performance advantage to getting settings/firmware/drivers aligned. (And note - some vendors have specific firmware/drivers that they recommend/support. That's not to say others won't work just fine, but these ones will be the ones they've tested specifically).

More generally:

  • always dual path your fiber channel. Ideally with two separate physical cards, going across two completely separate sets of switches.
  • keep the cards identical. Firmware, drivers etc. (You can mismatch if you're connecting to different storage infrastructure if you must)

I definitely recommend qlogic. And agree check interoperability/compatibility. Qlogic has some matrices on their site even if the storage vendor may not have it on their site (in this case LSI) –  ben Jul 8 '14 at 18:04

That's actually an LSI Engenio Class 4600 (0834) which was bought by NetApp in 2011 and is no longer available - I was struggling to find documentation either to be honest.

I know some are huge fans of Q-Logic FC HBAs but I'm personally a fan of Emulex ones and although I can't find any form of interoperability matrix for this product I think that if you stick to these manufacturers (or LSI's own of course) you will almost certainly be ok.

Engenio arrays were sold to OEMs for labeling and support, documentation from the manufacturer always has been a problem. If I am not mistaken, IBM has OEM'd them in their DS4000 line - the asker's variant is likely the DS4700. The IBM interop matrix indeed lists a wealth of OEM'd 4GB QLogic and Emulex HBAs as "compatible". –  the-wabbit Jul 4 '14 at 10:38
    
Good spot - so I know IBM rebadge NetApp filers but I didn't know they did that product set, sounds good –  Chopper3 Jul 4 '14 at 10:39

I am a huge fan of qlogic and not a big fan of emulex. I have had emulex issues in the past going way back which could influence my decision that I rather not work with them. Qlogic has top rate driver support and customer support and utility and tool support. I haven't checked in awhile but Emulex is usually 50% to 70% of the cost of Qlogic so if you are on a budget, I do agree that Emulex and Qlogic are the top two. I would still consider Qlogic. Also do your best to check interoperability/compatibility. Even if not on LSI's site, Qlogic has a well developed compatibility matrix. –  ben Jul 8 '14 at 18:03
    
@Chopper3 On the back is says "class 3600" instead of "class 4600". Does that change anything? –  Jasmine Lognnes Jul 24 '14 at 9:40
