P620 Quad AIC m.2 pcie adapter RAID performance?

2021-09-12, 0:10 AM

Hi,

 

I'm about to purchase a P620 with the Quad AIC m.2 pcie adapter. I intend to populate with 4 2TB NVMe drives in a RAID 0 configuration for maximum size and performance (I have a separate backup strategy).

 

I've reviewed several high performance NVMe drives, when I remembered a past experience with a RAID controller that did not perform well, so I never go to experience the true performance of the drives.

 

I've not been able to find any suitable performance benchmarks or technical specifications that would lead me to any potential bottlenecks with the RAID and expected performance. I don't want to waste money on high end drives if they will never operate at their top performance in a RAID 0 configuration.

 

Please can someone point me in the right direction.

Let me send this over to our Benchmark/Performance team and have them get back to you on this.

Per our internal benchmark/performance team, one of the tools Lenovo uses to measure disk performance is Crystal Disk Mark.  Depending on your type of workload, RAID 0 may not increase performance vs non raided drives.  If you need a single 8TB volume, then RAID 0 maybe your only option.  Also the Quad adapter supports PCIe Gen 3 only, so using Gen 4 drives will not increase performance.  Creating a RAID 0 array using the two onboard M.2 slots will run at Gen 4 speeds.

Thank you for the information.

 

It's a shame the card is only PCIe 3.0

 

There is an equivalent PCIe 4.0 card available from Gigabyte. It works with AMD RAIDXpert2 (which as I understand, is software RAID that's configured through the BIOS).

 

Obviously this isn't a card you can recommend, but can you see any reason why it wouldn't work?

That's correct, these 3rd party cards are NOT supported in the P620. However, though it should work in our system, there might be some stability issues that you may run into.

For anyone reading this, I ended up with the ASUS card and it's working fine after I enable bifurcation. Works with the AMD RAID setup as well.

@cosmicnet  

 

I just read this thread.

 

ASUS Hyper M.2 Gen4 x 16 AIC

I also have the ASUS AIC installed.

On my system it worked well up to firmware S07KT1DA

Firmware revisions 1EA and 1FA caused the card to fall back to gen3.

This was fixed in firmware S07KT21A

 

Gigabyte AIC

If you refer to the Gigabyte card mentioned by

@harrysmith0 , he reports it does not work well on his system at this moment.

Thanks for the heads up. I'm not a fan of ASUS but it looks like I went the right way.

I installed BIOS S07KT23A but it has not changed the behaviour of the Gigabyte AORUS Gen4 AIC Adaptor in my P620. If the PCIe slot is set to Auto (the default) it doesn't work. If set to Bifurcation x4x4x4x4 and Gen4 the system won't boot. If set to Bifurcation x4x4x4x4 and Gen3 it works. Strangely, I am getting good read speeds now (12-13000MB/s sequential read) on RAID10 despite this. But only Gen3 (6000MB/s) on write. Random speeds are not so good so if you can afford it buying bigger drives that might be better. But 8TB drives are expensive. It may be an issue with the nvme drives or a combination of the two that prevents Gen4. One other issue with Gigabyte AORUS Gen4 AIC Adaptor and probably others is that it is not really made to disassemble. The heat pads become fused to the drives and break up a bit if you try to disassemble. Not really ready for RAID easy swap out but that may be true of other adapters.

 

I noticed that the readme for S07KT23A says " S07KT1DA: - Upgrade the UEFI AMD RAID driver to 9.3.0.266." What happened to that?

 

AMD does not list here https://www.amd.com/en/support/kb/release-notes/rn-ryzen-raid-2-17-05-2306 that driver 9.3.0.266  supports Threadripper Pro. For this socket set https://www.amd.com/en/support/chipsets/amd-socket-swrx8/wrx80 it says Threadripper pro is supported. I decided not to try this driver.
