Hi, I've just finished building a new file server that has an Adaptec 2400a RAID controller card, to which 4x250GB IDE drives are connected. The card is right now running in hardware RAID-5 mode and I'm using the Linux I2O driver with kernel 2.6.14 (vanilla sources). The server is running debian sarge.
Using bonnie I get around 17MB/sec write performance and 30MB/sec read performance, which I guess is not too bad for a card like this. I'm wondering however if I could do better by configuring the card on JBOD mode and running software RAID-5 instead. The machine will mainly be used as a file server (for 1 user, me...). It's also mail server, dns server, web server etc etc but still very light usage. I might also be running some applications on it, like bittorrent for example. The CPU is a 3GHz pentium4 on a Gigabyte GA-4MXSV motherboard. Before I decide to just optimize the raw throughput by going to SW RAID-5 I'd like to measure real world NFS performance (and maybe Samba performance as well) to see how the machine behaves under NFS load. I don't want every CPU cycle consumed under heavy NFS load by software RAID since the machine needs to be able to do other things as well. Could anyone recommend a good testsuite to get some good IOPS numbers for example? Is runnoing bonnie over NFS the best thing? I will be connecting from a debian testing machine to execute the tests.
