slow speed array with hpsa driver

Hello !

We have server with Smart Array P410 and 8 drivers

4xSAS raid10 array and 4x SATA raid10 array

 

We have upgraded the kernel to 3.2 version and hpsa driver then disable the cciss

Now we have very poor speed from hdparm

 

With cciss driver and kernel 2.6.32  we have normal speed about 400MB/s on SAS and 250MB/s on SATA array disk

 

 


[root@s89:: ~ ]:# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 216 MB in 3.03 seconds = 71.37 MB/sec

[root@s89:: ~ ]:# hdparm -t /dev/sdb
/dev/sdb:
Timing buffered disk reads: 310 MB in 3.01 seconds = 102.85 MB/sec

Re: slow speed array with hpsa driver

Does this also improve the performance of the services running on the server?
