LSI 9211+WD Red = slow speed?

Recommended Posts

Using lsi 9211-4i with two WD red 4tb

I did not pay attention before, but copy from HDD to HDD is really slow, about 30-35MB/s, 40MB/s at top.

 

FreeNAS 11 stable with last updates

Ram 12 gb, and free about 4 gb

ZFS without encryption

LSI 9211 in IT mode, firmware 7.39.00.00 (P19), bios p20

What Im doing wrong?

 

P.S.B120i not trying yet

When I think of ZFS I think of a pool of drives running RAIDZ, but as you only have two drives I would tend to think you have it setup as a mirror. Although if it is configured as a mirror you would only see one logical drive, so you would not be able to copy between your drives. If you are using ZFS with the drives individual or JBOD, I have to wonder if the overhead of ZFS is causing the performance issue. Also, what is the advantage of running ZFS with JBOD, data portability?

copyng big file (~5gib) from one drive to another

Was the test run from a computer connected to the FreeNAS server or by using Rsync or cp on the FreeNAS server?

Hi,

 

Do you checked the disks on another operating system / file system?

Read it

P.S. I remember I had random (not stable) slowdowns speed HDD on LSI 9217-8i (IT), then I installed an additional active FAN on the cheap and the problem was gone. I'm not sure that this is your case.
