LSI controllers

[stlouis1]

I just migrated a solaris 11.1 system to a larger system and moved the pool onto an LSI controller thinking i would see better performance.....was I ever wrong

I had considered going to freenas and posted here to inquire about importing the pool but found I would have to rebuild it entirely.

right now I've tried an LSI 9211 (ibm 1015) and 1068E, both are giving me the same horrible performance. I used to see a solid 200mb/ps write speed locally, no I see a fluctating 0-115.

So if anyone here can confirm that Freenas works well with either of these LSI cards (preferable the 1068E as it saves me buying a second m1015 to hold the raid in my other server) I will seriously consider rebuilding the pool with freenas because this horrible driver in solaris is killing me

If your data is in a ZFS pool you should be able to just make a FreeNAS USB stick, import the zpool and see if it works for you. If you are happy then keep it. If not, then simply unplug the USB stick and go back to solaris. All of the system info is stored on the USB stick.

it's a solaris 11 zfs pool, my understanding was that solaris 11 uses a newer version of zfs than what it available for opensource and that anything opensource like freenas would not be able to read it, hence I would have to rebuild.

Hi stlouis1,

I run a 8 drive raidz2 of 1TB Samsung F3 drives with an IBM BR10i (LSI 1068-based) and it works great. I just ran a quick "dd" run & here's what I got (note: 16GB system memory, 24GB test file, no compression on the dataset)

Code:

[root@filer] /mnt/zpool0/dataset2# dd if=/dev/zero of=testfile bs=8192k count=3000
3000+0 records in
3000+0 records out
25165824000 bytes transferred in 49.651807 secs (506846084 bytes/sec)

I just ran that same thing and got this

solaris@srv-data:~$ time dd if=/dev/zero of=/tank/file bs=8192k count=3000
3000+0 records in
3000+0 records out

real 2:16.9
user 0.0
sys 13.5

so wow, thanks for the info Will, looks like i'm getting less than half of what you are in terms of speed. I would say that answers my question
