I have just purchased an HP ProLiant HP ML110 G5 server and install ed CentOS 5.2 x86_64 on it. It has the following spec: Intel(R) Xeon(R) CPU 3065 @ 2.33GHz 4GB ECC memory 4 x 250GB SATA hard disks running at 1.5GB/s Onboard RAID controller is enabled but at the moment I have used mdadm to configure the array. RAID bus controller: Intel Corporation 82801 SATA RAID Controller For a simple striped array I ran: # mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/sdb1 /dev/sdc1 # mke2fs -j /dev/md0 # mount -t ext3 /dev/md0 /mnt Attached are the results of 2 bonnie++ tests I made to test the performance: # bonnie++ -s 256m -d /mnt -u 0 -r 0 and # bonnie++ -s 1g -d /mnt -u 0 -r 0 I also tried 3 of the drives in a RAID 5 setup with gave similar results. Is it me or are the results poor? Is this the best I can expect from the hardware or is something wrong? I would appreciate any advice or possible tweaks I can make to the system to make the performance better. The block I/O is the thing that concerns me as mostly I am serving a 650MB file via samba to 5 clients and I think this is where I need the speed. Plus I am hoping to run some virtualised guests on it eventually, but nothing too heavy. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
