I s'pose you know, you have the world's most expensive electricity ? Even post-Enron California is only about a third that price. There must be a reason ?

The Keeper wrote: Sorry for the delayed response. WWN bindings under IRIX are typically only when you're operating in a fabric with a switch. When the drives are direct-attached, the drives look more like SCSI.

The Keeper wrote: Now that I see your hinv (or maybe I didn't notice before), I see you're using the Adaptec AIC-1160. I've never used that one, I've only ever used QLogic cards. Maybe the AIC-1160 is being stupid, I'm not sure. The LUN mapping should be persistent across the FC-AL ID's, so there might be a firmware configuration setting, but it'd be hard to get to in an IRIX box. Adaptec got out of the Fibre Channel and iSCSI business a very long time ago, possibly because they couldn't figure out what they were doing.

Does the AIC-1160 have a DB9 connector or an HSSDC connector? Either way, I'd probably suggest trying a QLA2200, because I never ran into the problem you're describing. I could tell from a Fibre Channel analyzer trace, but, well, those aren't very common.

Tell you what, drop me an email at my gmail account, with the username kalisiak. I'm sure I have copper QLA2200's laying around, and I can take a look and see if I have an extra HSSDC-DB9 cable if you don't have one.

I've replicated FC jedi's Chris Kalisiak's configuration from http://www.futuretech.blinkenlights.nl/fc.html (Ian's website):

Took a "relatively large Origin server", a netapp 14-disks (Seagate 300GB FC) lun array, and got those laughable results:

At the time of the tests the load was roughly ~40% on the netapp; so I'm trying to understand where is the bottleneck, plausible causes:

- qla2342 driver?
- single channel (2Gbps) FC, not appropriate? (This netapp, while using a 2Gbps GBic is pushing only 1Gbps at most). I should trunk more ports.
- gremlins

Saying all that, it's a noise level that is acceptable (just) unlike a 1u rack server.

BTW, good luck running that combination of monitors..

why dual GFX ? specific application need ?

where did you found the dual-carrier ? and how much it was ?

Anyone have any idea on fastfan and dual Vpro in an Octane? Maybe I missed something in my searches...

Thanks in advance,

not what he needs. he had a unix.install already which is the result of autoconfig so all what's needed was putting the new kernel in place as correctly pointed out by hamei
