Supermicro has refused to assist in troubleshooting. This is the last Supermicro product I purchase as their support is absolutely horrendous. They ran me around in circles for months wasting my time and then suggested that I contact sales to purchase one of their "certified compatible" server...

Unfortunately not for the embedded 3008 based controllers - I have to have SuperMicro provide me with a custom firmware.

From your C1 config: Flush Time(Default) = 4s Drive Coercion Mode = none Auto Rebuild = On Battery Warning = On ECC Bucket Size = 15 ECC Bucket Leak Rate (hrs) = 24 Restore HotSpare on Insertion = Off Expose Enclosure Devices = On Maintain PD Fail History = On Reorder Host Requests = On Auto...

Supermicro has terrible customer service the tech I have been working with is grossly incompetent, combative, and has some issues with understanding English. I think I have narrowed the issue down to this: Expose Enclosure Devices = Yes Shows on your C1 card, while it is listed as = No on my...

Here is a dump from StorCLI. Notice the "support JBOD=No" under the controller properties? Digging around on the Avago website this appears to be a bug that was fixed some time ago in the OEM firmware. I am wondering if SuperMicro is crippling the chip to sell more backplanes? I will give...

I have two cables and two IOMs, I will try different cabling scenarios and see if that makes a difference. I have already tried using only a single cable but I think I didn't try switching that single cable to the other controller. When I used two cables into a single IOM6 it sees it as a...

Just for S&Gs here is 64 threads (for all tests) on a 64 thread capable CPU striped across 3 IODrive2. Pretty good example of how Fusion IO devices scale well with CPU power.

I appreciate the help. This is going to be a project I think. Might have to track down some Xyratec controllers to toss in the shelf to get away from the Netapp strangeness. I am using my onboard SAS controller (on the Mobo) via a 8087/8088 pass through to a QSFP+ cable. I don't have any...

These are for high bandwidth NICs but might contain useful information: https://community.mellanox.com/s/article/how-to-tune-an-amd-server--eypc-cpu--for-maximum-performance https://www.amd.com/system/files/TechDocs/56224.pdf Bumping the Read threads to 4 made a big difference.

I am on an EPYC 7601 so all PCI-E lanes are hanging off of CPU dies, however there can be similar issues to a PCI-E switch when running very high bandwidth devices. I am wondering if I should try software to see if I can pin the fio driver to some idle cores. Part of me wonders if it is the...

Also THANK YOU for your help keeping these cards relevant for broke ass cheapskates like myself!

I figured out how to set all 3 at once with comma separation. All cards now reflect a 74.5W power limit, however it hasn't helped as I am still getting exactly the same performance issue.

Ok so here is some new weirdness. I can set the power override for a single card. I have tried comma separating them but it is only sticking for a single card. As soon as I set it for one card it changes back to the default on the other two.

I turned on power override for all of them with the wildcard option. Should I try it individually?

Sorry NTFS formatted. REFS is a dog.

I tried MegaCLI and MegaCLI 64, the latest versions I can find are from 2014 and it fails to locate the adapter. Is there an alternative for the 12Gb/s cards? I can't find anything on the Broadcom site.

MegaCLI according to the readme file does not support any of the 3008 based/9300 series adapters. Good point I forgot to mention I have IOM6 installed and MegaRAID reports them successfully negotiating a 6Gbp/s link speed in the enclosure, but I cannot get them to show up in Disk Manager. Do...
