Another BIOS RAID or host based RAID question

[Franco Bruno Borghesi]

Both 3ware boards are on similar based hardware: Tyan S5120AGNF (tomcat 
i915g), PIV 3 ghz-HT disabled, 2GB of RAM. Mylex board is installed on an 
old PIII 800mhz, 768MB of RAM.

I've run bonnie on the 3 servers, theese are the results:

 *3Ware 7506 4LP (ATA-RAID 5):
              -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU  /sec %CPU
          100 26773 21.0 25696  7.0 24083  4.4 106501 98.1 872573 98.5
86894.2 93.9


*3Ware 9500s (SATA-RAID 5):
Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU  /sec %CPU
          100 35912 27.1 37985  7.2 42063  6.6 115488 98.1 2237713
99.2 134675.6 98.5


*Mylex AcceleRAID 160 (SCSI-RAID 5):
              -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU  /sec %CPU
          100  9528 27.3  9839  7.8 11813 12.9 36905 98.9 169363 99.1
25536.9 98.3


None of theese servers are very busy, and the tests where performed under 
normal load. 
3Ware 9500s performs very well, but be carefull, acpi enabled hangs the 
server every day, and disabling it will hang it every 10 :(

If you're interested about ATA/SATA RAID you should try to get some 
information on promise boards too. Hope someone in the list can help.
