Dell PE R730XD and H730 (hba mode) only showing 150.00 transfer mode

[craig51]

all,

I have 2 dell r730xd (one 24 bay one 12 bay) with H730 mini cards set at "HBA Mode". i have been suspect about something since the performance does not seem any better than my R510 with H200 (flashed to IT). i ran dmesg | grep transfers and got this below

root@freenas130[~]# dmesg | grep transfers
ses0: 150.000MB/s transfers

when i run the same command on my R510 machines the transfers are 600.000MB/s

i am trying to find out if anyone else has seen the same thing? and is there a fix ?
i had thought about going to the actual Dell HBA330 or flashing one of my H330 to the HBA330 firmware as seen here

Flash/Crossflash DELL H330 RAID Card to HBA330/12Gbps HBA IT Firmware

Success! You can now flash the Dell PERC H330 (All Models) to IT Mode (HBA330). Big Thanks to BLinux for asking if it could be done! (Inspiration!) So I initially had a super long write-up, but that's way too long, you just need the compact steps. I linked the write up at the end of the...

any input appreciated

Did you found anything out here? I have the same problem.

TMUEKO,

This is what i found, regardless of what i did to a h730 it always showed 150.00 transfers, flash to IT etc, i did the same process to a H330 and it shows 1200.00 as well as i had a Dell stock HBA330 and it also showed 1200.00. i am not sure if it is more than a displaying the wrong speed issue since i saw no difference in performance after i put the H330 flashed to IT mode. I just stopped using the H730 and stuck with the H330 since it showed the right speed, just made me feel better. i did not see any performance difference since this machine never made it to production but if the transfer is only 150 i imagine it would cause issues. My suggestion would be to grab an H330 from ebay and flash it unless you can find an actual HBA3330 for reasonable price, you don't need to flash those.

Hi, I have the same issue with a H750, is there any news to this after almost 6 years ?

1. The problem is cosmetic, since LSI SAS3 controllers do not support 1.5 Gb/s SATA anyway.
2. There is no scenario in which you should be using a hardware RAID controller like the H750. No, setting it to non-RAID mode does not solve the relevant issues.

Thanks Ericloewe,

apparently there are no pure HBA controllers anymore, so using the H750 in non-raid. By saying the problem was cosmetic, does it mean my disks are well connected at 12Gb/s, but the driver is only reporting 1,5GHz ?

That might be what your Dell rep may be trying to push, but it is nonsense nonetheless. Still, even Dell currently sells HBAs in both PCIe card and proprietary form factors. The Dell H750 in particular seems to only exist as a plain PCIe card, which makes replacing it easy-to-trivial, with a plethora of suitable options from used LSI SAS 9211s to brand-new LSI SAS 9500s - and many, many options in between.

By saying the problem was cosmetic, does it mean my disks are well connected at 12Gb/s, but the driver is only reporting 1,5GHz ?

As I said, the controller literally does not support 1.5 Gb/s connections. It is rather likely that 6 Gb/s is in use, but you'd have to investigate it some other way.

Facing this situation right now, although with an R630 and H730P. Not entirely cosmetic. I can write at full or near full speed, but reads are limited to 150 mb/s. Didn't have this problem on Debian w/ ZFS.

That's not a SAS link layer issue, it's a driver/firmware issue, and it's a substantial reason behind the advice not to use those things. Swap it out for an HBA330 mini.

Side question: are you using Core at the moment?

That's the plan, it's just unfortunate that it's necessary.

Yes, but on a different box.
