So you think that if I move the QLA2342 from the 33MH slot to the 64MH slot, it
will be faster and will do a real parrallel work on each port?

I didn't understand what you mean?
there is only 3 slots on v240, which of them cannot handle dual HBA?

Those are the result of my preformance test :
time -p "dd if=/dev/zero of=/ZFS_pool/testfile bs=1024k count=20480 &&
/bin/sync"
(also I change on the server the kernel parameter -> ssd_max_throttle=32)

- I will try your test.
- But How the zfs cash affect my test?
- can you send me the guide that tell to change the sd_max_throttle to 32 on
solaris10 or solaris8?
there would me no more then 30 LUN active on the port but no simultanies.
- do you know if a HBA dual QLA2342 can use both 2 ports
stripe all of them maybe OK.
another 2 questions :
1. there is any concatination mathod in ZFS?
2. I test the prepormance by copy 512MB file into zfs pool that created from 2
luns with stripe,
one Lun came from Storage-controller-0 and connected through HBA-0
second Lun came from Storage-c
I want to configure my zfs like this :
concatination_stripe_pool :
concatination
lun0_controller0
lun1_controller0
concatination
lun2_controller1
lun3_controller1
1. There is any option to implement it in ZFS?
2. there is other why to get the same configuration?

I have Storage-SAN of HDS(AMS500), and I want to do striping on luns from the
storage. I don't want any raid-5(because I have one on the disks in the HDS
storage).
I only want to do strip on 2 luns(25GB each) that cames from different
controllers and deffrent fiber channel port(dual HBA).
