Thanks for the help, a solution to this problem is to update the bios, and after using the newest version of bios I can use AHCI mode on the sata controller, and indeed this is the problem.
But I had to install windows server to update the bios, then installed again using Linux.

This result: # hdparm -tT /dev/hda5
/dev/hda5: Timing buffered disk reads: 8 MB in 3.08 seconds = 2.60 MB/sec
First of all it should report /dev/sda and not /dev/hda
It is a horrible speed for modern disks.
Modern SATA disks show around 50-80 MB/Sec
I am sure ide0noprobe=no (or zero -- check docs) in the kernel mline will surely speed up in addition to other suggestions will dramatically speed up.
As will setting the operation mode in mode in BIOS from compatible to SATA. First thing i do on all HP servers when they are shipped.
