Fibre channel, XSan, Linux, any advice?


Hello

Does anyone have any experience of using Linux servers with fibre channel network cards? Specifically...

Which fibre channel PCI cards might I look at getting? (I have a QLogic fibre switch which I'd like to continue using)
Which Linux distro(s) is fibre channel best supported by?

Secondly, does anyone have any experience using an Apple XSan setup with Linux servers? Can it be done? If so, how?

Thanks
James

Do you have hardware laying around already, or are you in the pre-purchase investigation stage? If the latter, work with the vendor to identify the appropriate components.

... I already have an Apple XSan setup (comprising 4 XServe RAIDs, QLogic fibre switch) and six Apple XServe servers. Basically, I'm looking to replace the Apple servers with Linux servers. I want to find out...

- can I use the Apple Fibre Channel PCI cards in Linux servers?
- can I use the Apple XSan system with Linux servers?

... or will I need to get a new XSan system as well as new servers?

Any advice?

Thanks

Apart from the fiber switch, I'm not familiar with that (Apple) hardware at all. Any vendor support available for it? You might tackle it from that end to see if it's tested on Linux.

Also, what Linux distro are you looking to run? RHEL? If so, they have a hardware database you can search to determine whether hardware is tested/certified.

Xsan is really StorNext, Apple HBA is really LSI :)

jamoo -

I'm quite familiar w/ the xsan components you're talking about, the short answer is just.. yes you can do what you're talking about and the answer lies with storNext. it started on linux, and apple bought and borrowed the key components for their bastardization of unix so they could sell it as xsan on OS X. i used to install and integrate this stuff for a local bay area VAR and have really had it up to here with it all, but after finally finding budget to upgrade everything we needed to snowleopard (yes it was a service pack, YES it should have been free) and the latest xsan, not to mention upgrading our servers BOTH to intel macs so they can run snowey lepard in the first place (damn you apple) now things are running quite nicely, as we were promised yeeeears ago from apple about Xsan. I'm still ticked spotlight stopped working after one of the 10.x updates and then showed up as a "new feature" in xsan 2 but that's neither here nor there. sly move, apple. very sly.

- can I use the Apple Fibre Channel PCI cards in Linux servers?
yes. It's an LSI card. there's a quick linux script to get the model info of all your pci cards, which will tell you what you need to add to a "linux drivers" google search.... can't recall that script ATM.


- can I use the Apple XSan system with Linux servers?

You can use xsan and storNext together... but there are limitations... check this chart: http://support.apple.com/kb/HT1517 and do some research on your own. I'm not sure where all this is these days but storenext is your missing keyword.

....i must ask, what editing/gfx software were you hoping on running? for me that has been the only shortcoming in the linux world. hell yes it's stable but there has not been a strong enough push in the development and follow-through of any really mentionable motion graphics or video editing software in the GNU world... nuke seems interesting but shake was the crossover, an app Apple bought then crashed into a wall... seems their way with the most promising and cutting edge creative tools that come anywhere close to being a competitor within Apple's pro-geek-sumer price range that Autodesk hasn't already gobbled up and sells either as combustion on crap OS or smoke/flint/flame for an arm and a leg on a real operating system... you do the math. i guess we all just need to get a grant??
