Those disks are desktop drives, not enterprise grade drives. NEVER use desktop grade drives in a RAID array. You'll only have problems.<br />
<br />
Replace them with enterprise class drives and your issues should disappear. Probably best is to get drives certified for your server directly from HP.

How do I know a given drive is &quot;enterprise&quot;? Is there something specific I should look for in a make/model/or spec?

I have an HP ML150 G5 and I have set up a mirrored 1.5 tb drive array. I have been having trouble with Linux throwing the drive into read only mode when it is under aload (oracle backup). I think the issue has to do with slow performance on the drive. I ran dd to benchmark write performance and got this:<br />
<br />
writing 10MB: 69MB/s<br />
writing 100MB: 20MB/s<br />
writing 1000MB: 12MB/s<br />
<br />
My question is, is this normal for a Seagate Barracudda 7200.11 drive? And, is there anything I can to to tune this array? I am not a Linux guru. Just trying to feel my way through this. Thanks.

Slow disk throughput

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
