Hi ppl .
I am getting a IBM x3200.. This machine can only support up to 4 x 250GB SATA. I need to have a usable space of 500GB and mirror it to other 500GB. IBM proposed me to get 2 RAID cards. Do you guys think i can do raid 0 on the first 2 x 250GB HDD and raid 0 on the second 2 x 250GB hdd, both on hardware raid and then during the installation of centos 5, i raid 1 on both the 2 sets of hardware raids?
Thanks

Buy a single raid card that can support raid 10 or raid 1+0.

The card IBM recommended is only 0,1 and they will not warranty any parts which are not from IBM.

Then you could software raid the two raid sets, as they will show up looking like scsi devices. Is the card they recommend a true hardware raid card? Not a fakeraid like the ICH7 intel stuff. So IBM will not warranty the raid card. They have to warranty the rest of the system, and get a warranty on the raid card from the vendor. I have done it with HP several times because the crappy Adaptec raid cards they push are less than stellar performers, and their linux driver support seems way behind the windows drivers.
Which x3200 were you looking at? I could get up to 3.0 TB with 4 750 GB drives on the one I was just looking at. And optional raid5. You could just raid1 with 2 500GB drives.

The model i am getting is 436242A x32. IBM insisted that this machine is not tested with 500GB SATA, and insisted me to pick up 4 x 250GB. If this machine is able to support 2 x 500GB, I would just run software raid. The raid card IBM is proposing is a PCI card which cost abour USD$300. Can you recommend a good raid card which is able to do raid 10/1+0 and very well supported by CentOS 5?
Thanks

We dont have that brand in my country. Checked with some distributors and shops.
Any other favorites?
For SATA ? Nope.

I see. I just went to IBM's custom shop and was playing with the "build it" options. You are buying it through the Express Options program which doesn't let you customize the systems. If IBM won't give you what you want, you can try some of the other makers like HP. Or you can get a 3ware (AMCC) raid card. They are the best supported SATA cards in linux.

Thanks everyone. I found a local 3ware dealer. Keeping this dealer handy. If this machine does not support the 500GB, i will get a 3ware 8506-4LP.

is this machine available with a simple JBOD non-raid 4 channel SATA card? use linux native software raid 0+1... it probably performs better than their raid cards anyways.

As I am not confident to build and maintain the software raid 0+1, therefore, i decided not to get into that stage.
Thanks

IBM's website says you can use 500GB and even 750GB drives with their 'simple swap SATA raid'. whatever.
If you're using 4 x 250GB, have IBM configure it as a primary and secondary raid-1 (2 drives each). then, when you install CentOS, tell the centos installer to add both of those RAID volumes to a single VolGroup00 with LVM, then create your file systems on the resultant LVM. LVM will stripe the data across the two mirrors, so you'll get the equivalent of a raid10

Yes That is what i had thought. Total of 4 HDD is 3.0TB, so i presume each HDD can be 750GB. But the IBM consultant insisted that they had not tested x3200 with 500GB SATA HDD. If the machine can support that, I wont have a problem installing CentOS using raid-1 with 2 x 500GB SATA drives.
I wonder who should I listen to. The website or the consultant.
