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
