SAS and DSS

[To-M]

Are you downloading from the FTP site (1.18 will be in the DSS directory) or Web site? If Web site and need access to the FTP site email me at todd.maxwell@open-e.com

Alright, I'm running 1.18 now and still not seeing the LUN's on the SAS card. I'll try 1.21 on Monday when I get the flash modules. Beyond that though you said something about getting the issue to support. What would I need to do? Do you just need the source files from the LSI drivers? Or will you update the kernel to something that has a newer 'mbtsas' driver?

I don't suppose that getting command line access to compile my own drivers is an option?? :-)

Thanks,
Ryan

Just let them know that you need the updated for this card. We stopped command line access a long time ago because of the huge calls with typo errors. We almost lost our jobs! That won’t happen again. Sorry for the lock out.

OK, so I have the SAS card recognizing the LUN's presented by the Promise array. I had to download/install the 1.21 beta version. When is the 1.21 stable going to be available?

The only problem that I see is that it recognizes the LUNs 4 times over. Same serial number and everything. Not sure if that's a problem with the driver or a problem with the setup.

1.21 was released today. If the issue continues with this release send logs to support@open-e.com to see if the drivers need to be updated.

Could send me this access also?I would like to try it on my poweredge 1900

Thanks

Please contact me at todd.maxwell@open-e.com so I can provide this access for you.

So have you done any benchmarking on this? I have something similar:

Supermicro running DSS 5.0
Dual Qlogic 2460 (working active/active FC MPIO would be great - )
Promise Vtrak E610fD w/ 16 147GB 15k SAS drives.

Just wondering if using DAS SAS gives better performance that the direct attached 4GB FC.

theoretically yes it should be better. I think that its faster because its talking native disk language end to end. im not positive however but i will be testing that fairly soon:

dual port 4gb fiber channel VS. dual port 3gb SAS

I think SAS is more expandable by design as well. Just wait till you see SAS SAN's - people will be running back to fiber channel because it seems a heck of a lot more complex now.
