Re: E200 with Linux
anyway HP was unhelpful, if i ask to solve the problem (that is not only mine or ours, as confirmed by phone), they say that i need a software contract.
i am very tired, this is most likely the first and the last HP server.

Re: E200 with Linux
# dd if=/RAM/ubuntu-7.10-desktop-i386.iso of=/data1/testspeed
1425016+0 records in
1425016+0 records out
729608192 bytes (730 MB) copied, 55.278 s, 13.2 MB/s
/RAM is a RAM disk, /data1 is one of the drives connected to our E200.
At first I thought the problem was with the fact that Drive Write Cache was disabled, but I haven't noticed any improvement after enabling write using hpacucli.
We're using the cciss modules that came with the distribution by default. Is anyone using any other modules ? (i.e. my drive is accessed using /dev/cciss/c0d0p2 for example).

Re: E200 with Linux
This is with RHEL 5.2 x86_64. I've also found the kernel thread where there is talk about updating the driver because of performance. See the ChangeLog for the 2.6.26 kernel.
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.26
Search for cciss and you will find a patch submitted by Mike Miller of HP.
I tried the 2.6.26.5 kernel from kernel.org and still had serious performance problems. I think the performance was actually worse than what I was getting with the RHEL 5.2 kernel.

Re: E200 with Linux
I also talked to Adaptec, they said they do not support Ubuntu, but the driver source is freely availalbe. Anyone feeling up to the challenge?

Re: E200 with Linux
We just bought 4 ProLiant ML110 with Smart Array E200.
I have tried Ubuntu 8.04 with same slow write rates.
I hope HP will provide a driver or firmware update soon.
Thanks
