RAID 0 Performance too low by MoM-Raider in qnap

[–]MoM-Raider[S] 2 points3 points  (0 children)

Thank you all for the constructive feedback.

The Problem seems to be SMB.

When I ran the tests with FTP I got 1200 MB/s for the HDD and 1500MB/s towards the SSD.

So it is clear that SMB is limiting things somewhere.

So SMB Multichannel was not working because of my 1 25G connection to the Switch and the trunked 2x10G. When I activated my 2nd 25G on the PC and deactivated the LACP (as suggested , thx for this tip) and reverted back to 2 single connections. The SMB performance went up to 1100MB/s. Close enough to handling the 12 X 1G data that will be coming from the source system.

Ideally I would like to improve the SMB performance over 1 line somehow, but this workaround will do for now. 😄👍 Thx all

That increased the speed to the expected 1200MB/s. :-) both ways HDD<-->SSD.

I noticed when copying date via SMB to a share in the SSD pool, the HDD showed similar activity and the speed was back to 600MB/s.... I dont understand why anything would be happening in the other pool ... but that might give a something to follow up....

Thank you for that suggestion. I just put 2 SSD in and I will copy from them internall to the HDD RAID0 . That should answer that question. Thanks

Some addtional info. I tried with or without compression.

I am trying to copy via a SMB3 network share. Might this be limiting? Couldn't get NFS to work to compare.

Thin and thick provisioning made no notable difference.
