Dell PERC5i very slow? iSCSi

I appreciate that you've been helping, but no need to be rude. Maybe help me with a step by step guide, i have no unix/linux experience. This would have been easier if it were built into the freenas gui. -.-

FYI, i ran "camcontrol devlist" and it didn't show me any drives :( - this is the result:

<TSSTcorp CDRWDVD TS-H492C DE02> at scbus0 target 0 lun 0 (pass0,cd0)
<HL-DT-ST DVD-ROM GDR8164B 0D08> at scbus0 target 1 lun 0 (pass1,cd1)
<Kingston DT Micro 1.00> at scbus1 target 0 lun 0 (pass2,da0)

What should be in the GUI? There is no easy "step by step" guide for FreeNAS because there are SO many options available that you can't write a guide that even works for "most people". It really is about understanding what you are doing and applying that knowledge to achieve what you want. I don't think you have a clue what you want in the GUI, let alone what benchmark values you want.

In your case, and you just said so, you have no experience. So my advice is to start experimenting and seeing what works and doesn't. So far you've asked extremely broad questions that have no "yes" or "no" answer.

Based on your links and info that the 5i needs a RAID0 I'd say that's NOT the card to use. PERIOD. I had a system that I thought I had to do a RAID0 with, and after I learned how screwed up it is and how FreeNAS works but doesn't work optimally I took the very long process of converting each disk to a JBOD and resilvering... over and over.. for 16 disks.

As jgreco says, you really don't have a clue what you are talking about with regards to the test and its results. You can't just "run a test" and it give you valuable info. I can give you tests to run that will make you think your speeds are 10MB/sec and no faster despite having SSDs. So quit with this running tests and setup the FreeNAS machine, and start putting some data on it. See how it performs. Open and close your typical loads on it and see what happens. Definitely don't move data to the FreeNAS server, but test it with REAL useful data. Your results don't tell us a damn thing about how good/bad your performance may/should/will be. Bollar and I had a long discussion and he spent several days experimenting with various answers. The bottom line is that you have to just try it and learn what FreeNAS does and doesn't do.

The reason I stopped responding early on in this thread is because it was very apparent to me that you are living strictly for benchmark results. Give it up, just as jgreco says. It's wasting your time as well as anyone else who reads to think that your test results are valid..at all.

Just like jgreco, I'm done with this thread. I see no value in continuing to tell you what you already have read and ignored in this thread.

Ok, well I have the 8 drives in a raid50, so may have to raid 0 each seperately again and test each.

I checked in /dev and the da0 device is there for the raid. tried

dd if=/dev/da0 of=/dev/null bs=1048576

and the result is:

15256+1 records in
15256+1 records out
15998099456 bytes transferred in 517.600805 secs (30908181 bytes/sec)

And I told you that i only have those raid controllers. next time if you don't say i can't use them at the start, don't bother replying at all, that way you won't get wound up. I asked for help, not abuse.

i dont really understand why you cant see the drives on that card.

i do not have any of them configured with anything in the RAID controller BIOS

I'll erase the Virtual Disk tomorrow and try a camcontrol, see if i can see them. I agree pirateghost, not too sure myself. Just out of curiosity, what PERC are you running? I have tried the 5/i a 6/ir with a flashed TI firmware (Although oddly that didn't play ball and stayed at IR rather than TI. and now have the 6/i card.

i will find out for certain this weekend. i have more ram to add to my box so i have to pull it out of the rack and see.
