Slow parity Building and migrating with H200 IT Mode 12TB Disks

Featured Replies

Hello all,

 

I seem to run into some issues. I have bought a pre-flashed IT Mode H200 PERC.

Connected to it are 6 disks of which 2x 12TB and 1 of them is the parity drive.

 

However, I'm only getting 3MB/s partity write speeds, thus taking this parity build to take up to 30-40days?!

 

Is there any way I can improve these speeds?

I currently do have 2 SSD's in the array which I'm going to move to a pool. 

Currently I'm also migrating the data on theses 2 SSD's to other disks in the array using unbalanced but pausing or cancelling that task seems to hardly affect the speed of the parity.

There's something writing to disks 4 and 5, stop all writes and then wait a couple of minutes, speed should improve.
